Volkswagen Bulli Concept


Volkswagen has releases Bulli Concept, which will debut at the Geneva auto show..

The new Bulli measures 3.99 m in length, 1.75 m in width and 1.70 m in height. In relation to its width it has a wide track (1.50 m front and rear), and very short overhangs at the front and back. Its kerb weight is 1,450 kg.

The Bulli is equipped with an electric motor that generates 114 horsepower, along with a lithium-ion battery. VW said the Bulli has a range of 186 miles — surprisingly high versus most EVs. It accelerates from zero to 62 mph in 11.5 seconds and has a top speed of 87 mph.

Inside the cabin you will see a removable iPad which serves as the multi-function touchscreen on the center console and handles matters such as navigation. No tachometer is needed and no gear shift is present either. There's a rotary switch on the dash to engage the forward and reverse gears.

Another rotary switch to the left of the driver is used to control the lighting functions
  • Original design of the Volkswagen bus comes from that of Dutch Volkswagen importer Ben Pon. On 23 April 1947 Pon sketched a compact bus - a simple side view of a radically shortened public omnibus placed over the wheelbase of a Beetle with an ‘m' for ‘motor' written on it. This became the basis for the original Transporter or T1 which was launched in 1950.

Volkswagen has unveiled an all-new concept, the ‘Bulli', at the Geneva Motor Show. It is a development of the Microbus concept which made its debut ten years ago in 2001 and a new generation of Volkswagen people carrier - the first of which broke cover back in 1950 with the production of the first Transporter.

More compact than the 2001 concept vehicle, the new Bulli is powered by an electric motor and fitted with six seats and infotainment control via iPad. It is front-engined and front-wheel drive. On a wheelbase measuring 2.62 metres - slightly longer than that of a Golf (2.58 m) - the new Bulli measures 3.99 m in length, 1.75 m in width and 1.70 m in height. In relation to its width it has a wide track (1.50 m front and rear), and very short overhangs at the front and back. Its kerb weight is 1,450 kg.

This includes the weight of the energy source: a 40 kWh lithium-ion battery, which is concealed in the sandwiched floor behind the sills and powers the Bulli's electric motor. This engine produces 85 kW (115 PS) of power and 260 Nm (192 lbs ft) of torque and the theoretical driving range is up to 300 km (186 miles) - a high value for an electric car. With this electric motor, the new Bulli can accelerate from zero to 62 mph in 11.5 seconds and go on to an electronically limited top speed of 87 mph. The concept could also accommodate, as an alternative power source, one of Volkswagen's efficient petrol and diesel direct injection engines.

Like the original Samba bus, the Bulli presented in Geneva has two-tone paint and a distinctive ‘V' on the bonnet; its 18-inch alloy wheels with stylised chrome hubcaps are another tribute to the Samba bus.

Inside the Bulli has six seats: three on a front bench seat (which can be split and folded) and three on the rear bench which can be folded flat to maximise loadspace - or turn into a bed in the true spirit of the iconic campervan. When all six seating locations are occupied, a 370 litre loadspace is available; with seats folded, the cargo capacity of the 1.8 metre long interior increases to 1,600 litres.

A removable iPad in the centre console serves as a multifunctional touchscreen. Along with Internet-based applications and the media centre, it also handles phone and navigation functions. There is no tachometer (unnecessary with an electric motor) nor a centre console, nor gear lever. The latter is replaced by a rotary switch to the right of the driver, which is used to select forward and reverse gears. A push button in the same switch is used to activate and switch off the motor. Another rotary switch to the left of the driver is used to control the lighting functions.

Such hi-tech equipment is of course a far cry from the original Volkswagen bus, the design for which came from that of Dutch Volkswagen importer Ben Pon. On 23 April 1947, Pon sketched a compact bus - a simple side view of a radically shortened public omnibus placed over the wheelbase of a Beetle with an ‘m' for ‘motor' written on it. This was to become the basis for the original Transporter or T1 which was launched in 1950 - and is still popular to this day.

BENTLEY SUPERSPORTS ‘ICE SPEED RECORD' CONVERTIBLE DEBUTS AT GENEVA SHOW


Celebration of Bentley's world ice speed record- breaking Supersports convertible driven by rally champion, Juha Kankkunen

(Geneva, 28 February 2011) Bentley announces today its most potent and radically styled convertible ever - the 202mph (325km/h) Supersports ‘Ice Speed Record' convertible. This new model, limited to just 100 cars worldwide, is a celebration of the Company's world ice speed record set two weeks ago by Finland's four-time world rally champion Juha Kankkunen in a Bentley Continental Supersports convertible.

Driving the all-wheel drive, biofuel-powered 6-litre, 12-cylinder Continental Supersports convertible on the perilous frozen Baltic Sea, off the coast of Finland, Kankkunen achieved a speed of 205.48 mph (330.695 km/h) eclipsing his own ice speed record of 199.83 mph (321.6 km/h) set in 2007 in the Continental GT.

Both the new Supersports ‘Ice Speed Record' convertible and Juha's record-breaking Supersports will be on display on the Bentley stand at the Geneva Show from 1st March.

Wolfgang Duerheimer, Bentley's new Chairman and Chief Executive, said:

"Juha Kankkunen's drive was a remarkable achievement and worthy of a very special car. The Continental Supersports ‘Ice Speed Record' is a true driver's car that captures that unique Bentley spirit. It offers extreme performance, agility and an extrovert personality, while retaining the refinement, handcrafted luxury and comfort our customers expect."

Bentley's most powerful 6 litre W12 engine with FlexFuel technology

The 6-litre, twin turbo-charged W12 engine, produces 640 PS (631 bhp / 471 kW) - the most powerful Bentley ever - and 800Nm (590lb ft) of torque. Paired with a Quickshift six-speed automatic transmission, it launches the convertible ‘Ice Speed Record' model from 0-60mph in 3.8 seconds (0-100km/h in 4.0s) and reaches 100mph from a standing start in only 9.5 seconds (0-160 km/h in 9.4s).

The additional engine power of the new convertible is the result of fine tuning of the engine to optimise the benefits of the new free-breathing air intake ducts, intercooler system and the exhaust system.

And true to the Bentley tradition of delivering instantly available and exhilarating performance in real world driving conditions, the ‘Ice Speed Record' convertible will sprint from 50-75mph (80-120 km/h) in just 2.5 seconds.

In common with its Continental stable mates, the new Supersports model runs on both petrol (gasoline) or E85 bio-ethanol or any combination of the two. Pioneered in the Supersports coupe, this FlexFuel technology offers a reduction of up to 70 per cent in CO2 emissions on a well-to-wheel basis, a measure of a fuel's net contribution to the atmosphere, not just tailpipe emissions. The on-board fuel supply system monitors the content of the fuel tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel.

The all-wheel drive system provides outstanding traction in all weather conditions. The drive is transferred between the front and rear axles automatically via a Torsen centre differential. The standard 40 front/60 rear torque split provides optimum traction and modulation of line and attitude by 'throttle steering' for more enthusiastic drivers.

The new exhaust system with reduced back pressure benefits gas flow while delivering a sporty baritone note under hard acceleration. On light throttle cruising, the new Supersports model remains impressively refined.

Large diameter (420 mm front, 356 mm rear), carbon ceramic brake discs, with eight-piston calipers at the front provide fade-resistant stopping power. This lightweight system also reduces unsprung and rotating mass, benefiting steering response and handling. As with all Supersports models the ‘Ice Speed Record' is fitted as standard with Pirelli 275/35ZR20 ultra high performance tyres.

Dramatically extrovert styling

Just 100 examples of this dramatically styled new model will be built at Bentley's Crewe factory. The Supersports ‘Ice Speed Record' is distinguished by its vibrant and muscular styling cues that reinforce the uncompromising performance credentials of this extreme Bentley convertible.

Bentley's designers have selected three ‘stand-out' exterior paint colours for the new convertible: Beluga, Quartzite and, fittingly, Arctica White. These colours are complemented by a Dark Grey Metallic soft top with Bentley's refined three-ply composite construction.

The unique appearance of the soft top is created in the outer layer by a 'grey' acrylic fibre with a semi-transparent 'metallic look' in a twill weave construction. The car's potent performance is further accentuated by 20" inch, 10-spoke Supersports wheels with a dark tint finish.

Contemporary luxury craftsmanship and advanced technology

The dramatic character of the four-seat Supersports ‘Ice Speed Record' continues in the cockpit in which traditional Bentley craftsmanship and fine detailing are given an even more extrovert interpretation.

Traditional leather hides sit alongside a range of contemporary materials for a distinctly sporting style. This includes diamond-quilted Alcantara to doors, quarter panels and seat facings, and ‘soft-grip' leather on the steering wheel and gear lever.

Unique to the ‘Ice Speed Record' model, the high-gloss carbon fibre on the dashboard, centre console and roof panel, features a unique red weave. The theme continues with Pillar Box red piping to seats and doors, and Pillar Box Red contrast stitching to seats, door casings, steering wheel and gearshift paddles.

The front seats and floor mats also feature embroidered ‘Supersports' legends while the signature Breitling dashboard clock also has a red accent.

The Supersports ‘Ice Speed Record', despite its ice racing pedigree, is clearly no ‘stripped out' racer. Its highly specified interior has the highly-advanced touchscreen infotainment system from the new Continental GT that provides rich map imagery and a 30GB on-board hard drive.

An 8-inch screen displays the car's audio system, telephone, ride and comfort settings as well as the very latest navigation system, which uses both an in-car hard-disc drive and a DVD player to access route data. It also utilises dynamic navigation to avoid heavy traffic spots, locates destinations using geo-tagged photos from an SD memory card and is Google Maps-compatible for most markets.

The infotainment system, with 7-digit postcode entry, combines touchscreen controls and classic Bentley knurled rotary switches to offer instant usability. It is complemented by a new driver information panel (DIP) located in the main instrument cluster. The new wide-screen DIP employs TFT technology and enhanced graphics provide the driver with clear and easily accessible information about a wide range of car systems.

2011 Koenigsegg Agera R


The Koenigsegg Agera R will making its global debut in the Geneva Motor Show.

The Agera R’s body panels are draped over a carbon fiber monocoque whose rigidity is such that a roof is not required. Hence, it’s a removable panel that can be stowed inside the car. The owner of the example being displayed in Geneva is a skier, so the car is outfitted with a custom carbon fiber roof box developed in conjunction with Thule. It’s a single-piece system that replaces the Agera R’s standard roof entirely; when you get to the mountain, you simply swap the ski-box roof for the standard roof (which is tucked away in the cargo compartment).

The Agera 5.0 liter V8 engine produces a whopping 1115bhp making it the most powerful Koenigsegg ever produced. Exact performance figures are unknown at this stage, but thanks to the 1330kg dry-weight it is over half a ton lighter than the Bugatti Veyron. This creates a wonderful power-to-weight ratio. It is even capable of running on E85 bio-fuel.

The interior is Koenigsegg-lavish and covered by a removable panel, made possible by Koenigsegg’s carbon monocoque rigidity. That ability has been put to good use on this customer Agera R (it’s off to its new owner in Norway straight after the Geneva show – so keep your mits off) with a ski-holding roofbox – made by Thule – which swaps over for the standard roof panel when the call to the piste arrives. Other goodies on offer include something called a Vortex Generating Rim on the alloys which aids downforce.

Pricing for the new Koenigsegg Agera R starts at approximately $212,765 over the $1,410,380 sticker of a ‘standard’ Agera.

Press Release

Introducing the production version of The Agera and The Agera R at the Geneva Motor Show - March 2011

This year at the Geneva Motor show Koenigsegg is presenting the brand new Agera R - Quicker than lightning! The Agera R on the Koenigsegg show stand - production car # 83 - is inspired by the legendary Speed Racer theme, as specified by the owner of the car. Speed Racers main colour is white - so is snow. Equipped with special Michelin tires and a custom made Thule Roof Box - Speed Racer is ready to attack the ski resorts!

Last year Koenigsegg presented a pre-production version of the upcoming Koenigsegg Agera. Since then the pre-production car and several test mules have continued the Agera development program. The Agera pre-production car has been driven by several influential motoring journals, resulting in raving reviews and awards, such as for example becoming the "Top Gear Hypercar of the Year". Please see attached quotes from these test-drives.

All in all the production versions of the Agera are created to take the Koenigsegg experience to the next level both on the road and the track, still maintaining the largest luggage space in the industry in combination with the unique Koenigsegg door system and detachable/stow-able hardtop.

There are several differences between the pre-production car previously shown and the production versions. For example, the engine and gearbox configurations are different and some revolutionary interior, chassis and aerodynamic features adorn the production version of the Agera that has never been shown before.

TAKE ACTION

Although sharing the same values and philosophies as previous Koenigsegg models, the Agera takes the Koenigsegg experience to a completely new level.

Similar to all previous Koenigsegg hypercars, the new Agera is the brainchild of Christian von Koenigsegg. The Agera has come to life in order to set new benchmarks for Hypercars when it comes to control, handling, speed, comfort, practicality and sheer driving enjoyment, while combining these features with clean, efficient and beautiful design.

The name Agera set the tone for the new project. Agera means "to take action" in Swedish. It is also short for the ancient Greek word Ageratos which means "ageless". These two are very suitable meanings, for the car building the future of Koenigsegg.

THE DESIGN

The Agera is designed with the minimalistic "less is more" philosophy in mind. This philosophy means that the shape of the car has to be purely functional with no added features except those purely needed to meet regulation, added safety, ergonomics, practicality and aerodynamics. We believe that if this philosophy is followed, the car will also be beautiful as it is purely purposeful. A good analogy is the evolution of a dolphin that has had to meet similar criteria in order to reach their present configuration through the evolution of nature.

The Agera is proportionate, compact and muscular. Its timeless, efficient and distinctive shape is truly a testament to time. The original shape and concept of the Koenigsegg CC, created 15 years ago, is still valid, fresh and highly competitive today. The Agera manage to stay true to the original philosophy, shape and size of the original CC. At the same time, it looks, feels and performs like something belonging to the future.

THE ENGINE

Koenigsegg differs from other low volume hypercar manufacturers by the fact that Koenigsegg develops and produces its own engine in-house. This is, by most observers and competitors, deemed as more or less impossible or way too expensive to even consider.

However, year after year Koenigsegg has proved them wrong. Not only are the engines developed in-house, they also have class leading characteristics in many important areas. To mention a few: Lightest and most compact hypercar engine in the world, weighing only 197 kg complete with flywheel, clutch, dry sump system, Inconel exhaust manifold with turbo. The low engine weight is quite astonishing, as the Agera engine also has class leading power and torque characteristics. To give an example, the Koenigsegg 5 litre V8 bi-turbo engine develops more than 900 hp on 95 octane regular fuel, and more than 1100 hp on E85 bio fuel. The Agera produces over 1000 Nm of torque from 2500 rpm and in the Agera R format the engine has a peak torque of 1200 Nm over a 3300 rpm rev range, showing great flexibility.

These are extraordinary numbers considering the size and reliability of the engine without forsaking drivability or flexibility. This is truly downsizing, without drawbacks. These characteristics make it one of the most flexible and easy to use hypercar engines in the world.

To give a hint of how different the Agera engines are compared to other production car engines, it is easy to look at the BMEP value (Brake Mean Effective Pressure) in the cylinders during maximum power output. The best production diesel and petrol engines from other leading manufacturers have a maximum BMEP of around 22 bar.

The Agera engine has a BMEP of 28 bar running on 95 octane fuel and the E85 Bio fuel Agera R engines has an astonishing BMEP of 30 bar. These numbers show how extreme the Koenigsegg engines are compared to any other production engine in the world. The reason why Koenigsegg can obtain such BMEP figures is due to some proprietary and critical factors, such as:

  • A unique shape of the combustion chambers, improving the resistance against detonation.
  • High cylinder head clamp load, enabled by a specially designed engine block. This has proven to give a zero failure rate to combustion overpressure, even considering the extreme cylinder pressures.
  • A unique engine block design, where the cylinder sleeves are used to further stiffen the aluminium block.
  • A connecting rod design reducing TDC dwell time and therefore enabling higher mean pressures without detonation.
  • Exhaust manifold and intake plenum trumpets designed to ensure absence of RPM peak resonance and back pressure.
  • An efficient ejector pump system reducing the crankcase pressure and aerodynamic losses.

The Koenigsegg engines also meet all the required emission standards in the world. This is nothing short of astounding, given their size and power output.

Koenigsegg has its own engine lab, with simulation programs, rapid prototyping machines, engine and chassis dynamometers, and a 1.7 km test track adjacent the factory enabling Koenigsegg to take the cars to 0-320-0 km/h at any time. Furthermore, a 25 minute drive away from the Koenigsegg Factory there is Knutstorp Racetrack, which is described by many as a miniature Nordschleife. Here Koenigsegg can put the engine and car through serious testing and make sure they work in perfect harmony. This gives Koenigsegg unique possibilities to develop technologies normally exclusive to much larger companies.

No other production engine in the world, regardless of car type, has the same amount of power potential compared to its EU cycle average CO2 emission(310g of CO2) or cycle fuel consumption( 14,7 litre per 100 km / 16MPG). However, what makes Koenigsegg most proud is how drivable, smooth, responsive, torquey and reliable the engines are - especially given their extreme performance.

The Agera engine complies with the most stringent environmental regulations in the world, EU5 and LEV2, and delivers a significant power increase compared to previous Koenigsegg engines.

Fuel consumption, and thus CO2 emissions, has been lowered. This is an astonishing feat for a 900+ hp hypercar. Turbo response is of vital importance when it comes to driving pleasure and the possibility to control massive amounts of power. Therefore Koenigsegg has joined forces with Borg Warner and adapted to the latest technology when it comes to turbine materials. The Agera R turbines are made from a material called Gamma-Ti which is an inter metallic compound comprised of aluminium and titanium. This new material drastically reduces the inertia of the turbine wheel and axle and therefore gives improved response. Furthermore Koenigsegg has coupled this latest generation turbo technology with patent pending and proprietary response/back pressure reduction system, invented by Christian von Koenigsegg to really give the Agera engine a competitive edge when combining maximum power while complying with the strictest emission regulations in the world.

Furthermore the large air to air intercooler on the left side of the engine sucks enormous amounts of fresh air, eliminating the need for water in the intercooling system, thereby saving weight and avoiding heat soak issues, during extended performance driving.

Following the Koenigsegg tradition the engine has a dry sump lubrication in order to lower the engine as far as possible in the chassis and have full control of the crankcase oil even given the massive g-forces involved.

The large 80-litre tank ensures long driving range, due to the relatively low average consumption. The Agera follows the previous generation Koenigsegg and has its fuel tank well protected, built-in centrally into the carbon fibre monocoque chassis. Since the fuel is centrally placed in the car, the weight distribution does not change regardless if the tank is full or empty. Thanks to the safe fuel tank position, the challenging US high-speed rear impact test, was passed at first trial.

The Agera R has four intelligent bio fuel grade return-less fuel pumps to deliver the correct amount of fuel at any given time. This reduces the energy needed to operate the fuel pumps and eliminates the waste of excessive fuel transport.

The inconel/titanium patent pending exhaust system is key in order for the Agera to achieve its remarkable emission and power levels. The exhaust system uses a completely new principle created by Christian von Koenigsegg. The new technology drastically reduces back pressure and gives earlier catalytic light off than any other turbo exhaust system. At the same time the acoustics of the exhaust has been examined carefully in order to maintain the typical Koenigsegg thunderous growl.

THE TRANSMISSION

The newly developed 7 speed gearbox for the Agera features a world's first dual clutch system for a single input shaft gearbox. In order to keep the gearbox light, compact strong and reliable, Koenigsegg together with Cima chose to develop a new gearbox type that enables the use of a combination of a dry and wet clutch system, in order to get class leading shift times. First there is the normal twin disc dry clutch that operates in a traditional fashion. Then there is a hydraulically operated wet clutch-brake inside the gearbox that is engaged during each up shift in order to slow down the input shaft, simultaneously as the gears are changed and prior to the normal synchronisation. This cuts the synchronisation time by two thirds, as the gear is pre- synchronized. The result is a very sporty, smooth and extremely fast shift. Compared to a traditional DCT system, this gearbox is lighter, smaller, has less moving parts and gives a more distinct shift feel, with almost no interruption to the acceleration. Furthermore, the electro hydraulic shift mechanism actuates the shift forks directly with no intermediate mechanical parts. This brings down the inertia of the shift mechanism and any potential slack is minimized since the shortest possible path of engagement is achieved.

The entire transmission weighs only 81 kg, which is by far the lightest 7 speed Hypercar transmission in the world. The transmission can also be set in full auto mode.

The small size and very low weight, considering the longitudinal 7 speed layout, made it possible to maintain the shortest in class rear overhang, and thereby excellent central mass position and neutral behaviour in extreme conditions.

Koenigsegg E-Diff

The Koenigsegg Electronic Differential (E-Diff ) is lighter and faster, compared to traditional E-Diff solutions. The difference lies in the fact that Koenigsegg has retained a limited slip differential with plates and ramps with a built-in amount of analogue limited slip functionality. This means that the active hydraulic element can be smaller, more compact and therefore faster and lighter compared to traditional E-Diff solutions. The analogue part of the functionality also has zero processing time as it reacts directly. The analogue system is supplemented by a digital active system.

This way Koenigsegg has obtained one of the lightest and fastest E-Diff solution on the market. Furthermore the Koenigsegg developed algorithms that control the E-Diff, takes input from; throttle angle, g-force, steering wheel angle, yaw angle, car speed, engine rpm, selected gear, plus weather condition.

The way all this data is analysed and how the car reacts to this data also makes the Koenigsegg E-Diff unique and that makes the Agera very safe on the limit and improves performance and feel.

The Koenigsegg E-diff works in harmony with the new traction control system that is the fastest reacting in the industry, with auto adapt functionality to different road conditions and driving styles as well as several manual settings.

THE CHASSIS

The Agera's unique carbon fibre monocoque chassis is designed to achieve its maximum stiffness without a roof, as the roof is detachable and stow-able in the front of the car. This in itself is an unusual feature for such a compact Hypercar. The Koenigsegg carbon monocoque chassis has an astonishing stiffness of 65.000 Nm/deg and only weighs 70 kg including the integrated fuel tanks.

The result of constant weight saving exercises is a dry weight of only 1330 kg making the Agera the lightest fully homologated Hypercar presently in production.

THE SUSPENSION

The suspension geometry of the Agera was designed to further enhance the award winning behaviour of the CCX. The Agera track is wider at the front compared to the rear of the car, compensating for the narrower front tires and giving the car a square stance of 2 meters in both the front and the rear.

In typical Koenigsegg tradition, the Agera has the longest wishbones of all hypercars presently in production. Long wishbones have several advantages - for example: less track width deviation during wheel movement or cornering and improved geometry over a longer wheel stroke. This is one of the reason why F1 cars have very long wishbones. The wishbones are produced from seamless aeronautical chrome-molybdenum tubing, in order to minimise weight in combination with maximum strength and stiffness.

The extremely strong and light uprights are machined from 7075-T6 aeronautical grade aluminium, and contains 240 mm SKF dual angle contact bearings, normally only found on Lemans prototype cars. The very large bearings contribute to the overall stiffness of the wheel assembly and therefore give better control, handling and comfort. The uprights have large 4.5" diameter carbon fibre cooling ducts for the brake discs in order to maximise brake cooling.

Brakes

The Agera is equipped with the absolutely latest ABS technology and is based upon, a very lightweight and performance oriented, racing ABS system. The system makes it possible for the ABS function to react to differently depending on performance mode. Furthermore the ABS braking system operates on massive 392x36 mm and 380x34 mm ventilated and drilled ceramic discs, for unparalleled braking performance and zero fade regardless of track or road condition.

RTD (Rear Triplex Damper) Suspension

Christian von Koenigsegg has invented and pioneered a new type of rear suspension system for a road car. The Agera has a shock absorber and spring connecting the right and left rear wheel. This system gives unique benefits as the two rear wheels can influence one another when desired.

There are multiple benefits of this system. For example, the extra spring and damper works in series with the normal spring and dampers allowing their spring and damping rates to be lowered. This results in increased comfort and better handling on rough and wet surfaces without compromising dry track handling.

Furthermore the RTD system has an anti-squat effect. Traditional anti-squat systems are designed into the geometry of the suspension. These systems do not add any components or weight. However they compromise the geometry of the suspension for other aspects of handling than anti-squat.

By adding the RTD system, Koenigsegg can maintain true suspension geometries for handling, but still have the anti-squat feature and harvest other new found benefits. As the RTD system compliments the normal dampers and springs, these can be made lighter. Hence, the added benefit does not significantly affect the overall system weight.

DEDICATED MICHELIN TIRES

Koenigsegg continued its long standing partnership with Michelin in the tire development for the Agera. Hence the Agera features specially developed, latest generation Michelin Super sport tires.

Due to the tires, advanced suspension and aerodynamics, the Agera achieves lateral accelerations up to 1.6 g in dry conditions with improved handling in wet.

The new tires were developed for the Agera through testing at the Michelin Ladoux test centre in France. The tires fitted to the Agera are rated for speeds over 420 km/h making it the highest top speed rated tire in the world, whilst offering cup tire levels of grip and outstanding wet performance , all in one package. Koenigsegg are very proud of being a selected development partner of Michelin.

VGR - Vortex Generating Rim spokes

The Koenigsegg VGR wheels are not only for looks. They are real air turbines, increasing the down force of the car by measurable amounts and improve brake cooling. All four wheels are individual so that turbine blades always face the correct direction for extraction. Given that the offset and width is different front to rear, all four wheels have their unique design. The VGR wheels are forged and then fully machined to the final shape. Due to the forging and machining process all excess material has been removed minimising weight, whilst displaying outstanding levels of stiffness.

THE AERODYNAMICS

The Aerodynamics of the Agera has been honed and perfected over many years in CFD and wind tunnel in order ensure best possible outcome. Even with the massive dynamic rear wing, the drag of the Agera is only Cd 0.33, in high speed mode and Cd 0.37 in track mode. Even though the Agera is a full 2 meters wide, it only has a frontal area of 1.87 m2. This results in a Cd*A value of only 0.62 and thus a theoretical top speed of around 440 km/h (Agera R), given the gear ratio and power available. All Agera models are limited to 375 km/h in standard mode, but can be unlocked by Koenigsegg for shorter periods of time, if all necessary conditions are met, such as road condition, tire wear, service level of car etc. The car is set in full speed mode by unlocking the top speed mode in the Infotainment system.

The two large side air intakes greatly add to the Agera ?s high speed stability as they ensure that the pressure point of the car is behind the mass centre of the car. This makes the car more directionally stable with increasing speed. This is a crucial safety feature when it comes to driving at extreme speeds. Great care has been taken that the car also is stable under high speed braking. The front splitter and rear diffuser has been designed and optimized with this in mind.

For maximum performance and safety it is important that the down force stays as constant as possible even in yaw situations. Therefore the rear diffuser was developed and evaluated specifically to give substantial down force even at wide yaw angles.

Dynamic rear wing

Hypercars of today generate massive amounts of down force in low to medium speed and less down force in very high speed, in order not to overload the tires and not to create too much drag. Most hypercars therefore have heavy hydraulically operated wings and flaps to cater for this need.

Koenigsegg however, following the "less is more" philosophy, has designed a dynamic system to that take care of the above described needs. The most visual and obvious part of this system is the new dynamic rear wing. The wing changes its angle of attack, not with the help of hydraulics, but with the pressure of the wind. It is therefore dynamically controlled by the speed or wind resistance at any given moment in time and thus actually compensates for headwind or tailwind at the same given speed. This is an intelligent way of dealing with adaptive aerodynamics, as the system becomes lighter, less complex and more intuitive compared to heavy and complex hydraulics systems. Koenigsegg had to work heavily with CFD in order to create the dynamically controlled adaptive aerodynamics of the Agera.

Furthermore, an interesting multifunction feature of the adaptive wing is that the pylons for the wing also act as air extrusion channels. The air channels goes from the engine bay to the back of the pylons, thereby creating an air passage. This causes a venturi effect, from the air rushing past the pylon, evacuating hot engine bay gases, reducing pressure in the engine bay and increasing the flow of cooling air through the side radiators. This also means that the pressure under the car is reduced and giving more low drag down force.

THE INTERIOR

The interior of the Agera is like no other car. No other materials than those deemed worthy by Koenigsegg are allowed in the interior. This means that what you get to touch and see inside the Agera is only aluminium, carbon fibre, precious metals, alcantara and aniline leather. All switch gear is highly bespoke and features wonderfully unique solutions, as for example the Koenigsegg Ghost light, that make solid aluminium buttons gleam with LED powered symbols appearing out of nowhere.

A world first in the car industry. The illumination shines through the billet aluminium buttons and surfaces by way of almost invisible micro holes, creating excellent visibility of the symbols as well as a very clean and stylish appearance, framed by an all-new carbon fibre centre console and tunnel assembly.

The new super light full carbon airbag steering wheel incorporates many vital functions directly in front of the driver. Similarly to the CCX, the shifting paddles are mounted directly on the steering wheel to enable shifting without taking your hands off the steering wheel during hard cornering.

The central high-definition touch screen infotainment system controls the audio functions, satellite navigation, Bluetooth phone and secondary functions such as performance meters and car telemetrical data.

The very comfortable and optionally heated carbon seats are great for long journeys but also give excellent lateral support when needed.

The Interior of the Agera is truly minimalistic and efficient in the purest Swedish sense. Nothing in the interior is there only to add visual drama; instead everything is there for a functional purpose. According to Koenigsegg, this is the essence of beauty, as it follows a less is more philosophy that embodies every engineering aspect of the Agera.

CI - Configurable Instruments

The CI is specifically developed for the Agera by Koenigsegg. It features a unique and configurable interface that can be adapted to driver specific demands. As it is connected to the cars CAN bus system it freely communicates with the infotainment screen and all other functions in the car.

By pushing the left stalk button, different priority graphics can be chosen, depending on need. For example in track driving mode, there is a focus on; RPM, pressures, temperatures, lap times, and g-forces. Compared to GT mode, where: car speed, auto shift, satnav, power, music etc is prioritized.

THE LUGGAGE SPACE

The luggage space is something Koenigsegg is very proud of. It is the largest luggage compartment in the hypercar world, with a space of over 120 litres. It is so well shaped that it actually can fit the one piece Agera roof/hardtop, meaning the driver can choose to go open or closed at any given time during a longer trip. Given the fact that Koenigsegg has engineered the roof to fit the car, it is actually also possible fit a set of golf clubs. This is unheard of in the hypercar world. Given the high comfort level and the large luggage space, the Agera can truly been seen as one of the first GT hypercars.

Custom Carbon fibre Thule Lightning Roof Box

At the 2011 Geneva Motor show, Koenigsegg presents the Koenigsegg winter package - the first lifestyle packages offered from Koenigsegg. The main element of this package is the exceptional Lightning Roof Box System.

The Lightning Roof Box is developed together with the Swedish rack and roof box manufacturer Thule. The high performance lightweight box is made completely from carbon fibre and has been through several iterations of CFD simulation to ensure it is safe up to 300 km/h, making it the fastest roof box in the world.

The roof box, which has an incorporated roof panel, replaces the normal roof in under 10 minutes. The standard roof is then stored in the luggage compartment in the front of the car, so that when the driver arrives to his destination, the roof box can be quickly removed and the normal roof can be put in place for a more elegant look.

The Lightning roof box truly enables the driver to use the Agera for longer trips with massive luggage. This gives a whole new spectrum of hypercar utilization.

The winter package also includes Michelin snow tires on forged Koenigsegg wheels and custom designed Koenigsegg skis from the Swedish high end ski manufacturer, Extrem.

Part of the winter package is also a Swedish winter resort experience in Åre - Sweden's most popular skiing resort and the place of manufacture of the Koenigsegg skis.

During the stay in Åre, the Koenigsegg customers will be fitted for their skis and they can witness first hand when they are being hand made in "Åres skidfabrik", a state of the art ski production plant.

While their skis are being made, they will be checked into the delightful Copperhill Mountain Lodge that is towering snow-capped forests and sparkling frozen lakes.

The following day the skis are ready for use and Åre ?s many and varied ski slopes are available for test runs, in direct access from the Copperhill Mountain Lodge.

Together with the Golf club options this marks the start of the Koenigsegg extended lifestyle program for Koenigsegg cars. We would also like to thank Full Tilt, Houdini Sportswear, Sweet Protection, Sport Lodge'n Trysil and Moods of Norway, for assisting us in creating the winter experience at the Geneva motorshow.

THE ELECTRONICS

Semiconductor Electric Control Central.

Not only does Koenigsegg develop their own engines, but also many of the electronic control units, CAN protocols, and management strategies are developed in-house. If you would look closely at many of the circuit boards in the car, inside the control units, you will find the name Koenigsegg in scripted directly on the circuit boards.

Of course there is no self fulfilling need to develop so many critical items in-house, unless it gives the car a competitive edge doing so. This is actually the main reason for Koenigsegg doing it. This, for example, gave Koenigsegg the possibility to pioneer the CCXR and Agera R - the two first environmentally conscious hypercars in the world.

An example of this development is In the Semiconductor Electric Control Central. The ECC controls most of the electronic functions in the car. Most physical fuses or relays have been replaced by software controlled semiconductors which are configurable in function and enable monitoring all power and threshold values. The ECC communicates via CAN with the infotainment system in order to display necessary information to the driver. For example if a door is open, a lamp is broken, or not all roof locks are tight in place, information will appear on the instruments as all electrical functions are controlled and monitored by the ECC.

Intelligent Lifepo4 Battery - ILB

The Agera is the first combustion engine powered production car in the world, with an intelligent Lithium Iron battery as standard equipment. First of all, this battery type saves significant weight and is more compact compared to traditional led acid batteries. Secondly lithium iron cells cannot reach thermal runway, unlike Li-ion batteries, which makes them very safe for automotive use.

Furthermore, the ILB carries many intelligent functions, developed by Koenigsegg together with the battery supplier. Hypercars tend to be parked long periods of time and therefore their batteries can be drained if the car is not hooked up to a trickle charger. Even though all Koenigsegg cars come as standard with a trickle charger it is not always easy to remember, or even possible depending on location, to use it. It is also possible that a driver sometime forgets to turn off all consumers, like parking lights etc causing early battery drainage.

Koenigsegg has therefore implemented a minimum current protection mode, to make the above issues something of the past. The new ILB therefore has an intelligent circuit built into it, so if the car is left on or standing for a long time, the battery shuts down when the voltage drops below a certain threshold. The shut down does not occur sooner than a traditional battery would have been left depleted and useless, so it does not take away any expected battery capacity. Then, if any essential buttons or a door knob is touched, the battery kicks back into life for 5 minutes and has enough power to operate all the functionalities in the car and start the engine and thereby giving charge back to the battery. Given this strategy, battery concerns are a thing of the past. No matter of the behaviour of the car user. To prove a point you can leave the car with the high beam on and the stereo at full blast in the evening, without the engine running. Wake up in the morning, open the car door, start the engine and drive away. Alternatively, leave the car for a couple of months, open the door, start the car and drive away.

2011 Mazda MX-5 ice racing


Mazda held an MX-5 race on ice recently with teams from around the world comprising journalists, TV fans and readers competing in Sweden.

The four-hour race featured 20 of the roadsters, all fitted with studded tires, battling it out on a three-mile circuit composed of snow and ice. The competitors not only battled each other, but chilly temperatures as low as -24 degrees Fahrenheit. The Australian team was the favorite going into race day and they held the lead most of the race until a late spin allowed the Russian team to take the win, having completed the most number of laps.

The drivers’ roster was made up of automotive journalists and Mazda fans who won contests to participate. As not all had racing experience, Mazda provided two days of instruction beforehand. Ice racing is dear to our hearts; we’ve raced cheap winter beaters on a frozen lake, and competed in a sanctioned event with our long-term Subaru WRX STI. See Mazda’s short video below for hot Miata-on-ice action.



Press Release

Mazda MX-5 on Ice


  • 4 hour race for journalists, TV fans and readers
  • 20 modified racing MX-5s set to start
  • Extensive programme with training sessions, qualifying and the race

Åre, Sweden, 21 February 2011. Mazda opens the 2011 motorsport season on Swedish ice. After the successful MX-5 Open Race last year, Mazda is inviting racing enthusiasts to Sweden for the MX-5 Ice Race from 21 to 24 February 2011. A total of 20 modified MX-5s, tuned for driving on ice and wearing spike tyres, will participate in the four-hour race on the ca. 5 km grid.

The MX-5s will be piloted by teams from 26 participating nations, among them motor journalists with racing experience, and TV fans and readers who won tickets to the event in special contests. The four-day event in Åre, Sweden will include two extensive training sessions, a qualifying session to determine pole and starting positions, along with the race itself which is divided into two sessions. When the snow settles, the team that drives the most laps during the four hour race will win.

Mazda MX-5 Ice Race provides exciting Finish

Lake Kallsjön, Sweden, 24 February 2011. Mazda's MX-5 roadster proved again yesterday its pure sports cars genes, this time on ice in Sweden at the Mazda Ice Race 2011. Clear blue skies and polar temperatures provided the right conditions for an exhilarating festival of drift and control as drivers from 26 nations competed in specially modified roadsters for a podium finish.

Day 1 – the Aussie's make it look easy
After Tuesday's practice sessions and qualifying, a clear favourite emerged with the Australian team, which dominated Day 1 and took pole position. They also won the hearts of everyone by wearing swimming trucks over their racing overalls – in honour of summer down under – and driving with a tiny kangaroo mascot fastened to the top of their car's safety cage. They made it look easy on Day 1 with their only real challenge coming from the Russian team, which took second on the grid.

Day 2 – Russian Heroics and Belgium Consistency
Race day featured beautiful blue skies, glistening snow and a morning temperature
of -31º C. This ensured ideal conditions on the ice of Lake Kallsjön, which is located in the Östersund region of west-central Sweden. The race itself was conducted in two sessions, each two hours long, with the car completing the most laps the winner. Like last year's MX-5 Open Race in Italy, it was drifting control and not pure speed that proved the decisive factor in the race. The Australians continued to dominate as they had on Day 1 and led for nearly the entire race. But then a small mistake, a spin-out, and Russia overtook them at the end, holding on for the chequered flag; with Australia second.

Russia's win followed some amazing heroics from the team. They began the race in second place but spun-out early, fell back to 14th, only to battle their way back to second by the end of the first session. They then patiently held this spot, hoping for a miracle, and were able to capitalise on Australia's misfortune at the end of the final session for a truly exciting win. The Belgium team displayed the consistently good driving you would expect from last year's MX-5 Open Race winners, coming from far back in the pack to take third. The unforgettable day out on the ice culminated with a Champagne spray on the podium from the three winning teams.

The Mazda Ice Race 2011 was crowned later that evening at a gala dinner and show for pilots, teams and invited guests who had won a Mazda competition in their home countries for a place at the event. Jeff Guyton, Mazda Motor Europe's President and CEO, gave a short speech and presented trophies to the tired but happy winners. This was followed by dinner and a celebration of MX-5 Ice Race memories lasting late into the night.
