    I like it. Front does seem to have quite a bit of F430 in it, but I can forgive that. Given aero and packaging constraints it's pretty hard not to look like some existing car.

    Keeping in line with the CC shape which is fine I guess, especially for a start-up company that probably still doesn't quite have the resources to make a whole new body.

    (from Koenigsegg Press Release)

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

    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”.

    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 presynchronized.
    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.

    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.

    Published Independent Test Drive Reports Pre-Production version of the Koenigsegg Agera

    0-60 mag USA by Matt Tuccillo:
    Grip is nothing short of epoxy like. Then as we head out to regular B-roads, the Agera composes itself perfectly. It’s docile even. You could easily daily drive it in comfort. The spring and damper rates offer a firm, yet not crashing ride, ride over most imperfections, and assuming you can find a bit of a dry pavement in a corner, the sheer amount of mechanical grip-out back will slingshot you through the apex before you are aware that you have arrived at the next.

    Top Gear Mag by Bill Thomas:
    It rides beautifully, almost softly, breathing deeply over harsh bumps, and longer undulations, and combining that with body control and cornering agility from the very top drawer. I couldn´t give higher praise. I absolutely love it. The most exciting supercar on earth, bar none.

    Sportauto Germany driven to the limit on the Dubai Autodrome:
    Is it time to have fear? No, the Agera is by no means a motorized cannonball. Dis-ingenuousness is not its thing. Despite the slightly rear-heavy weight distribution (45 to 55 percent) the car shines on the first fast track kilometres with neutral handling. While the Michelin tires slip slightly at the front axle during tight turns, they shine on the rear axle also with forced gas use from the apex with good traction. The Agera is truly a good-natured racing machine that easily swallows load changes. Click, click, click. The new seven-speed sequential gearbox works faster and thanks to co-rotating shift paddles behind the steering wheel, it is less complicated than the semi-sequential gear lever predecessor.

    Sportauto France by Laurent Chevalier:
    The build quality and pure sensations of the Agera truly makes it belong to the Elite of the supercar world. With AP Racing 15.7-in. ceramic discs up front and well-calibrated ABS, the Koenigsegg simply stops. Dead. My passenger is laughing hard. Welcome to Planet Koenigsegg. Koenigsegg’s cars are not only beautifully finished. They’re astonishing fast. Inside, the Agera resembles a Business Class space capsule. After clambering in -- which requires a few contortions -- you discover a workspace plusher than that of a Pagani. With its doors covered in leather, and its thick bucket seats and roof lined in Alcantara, the Koenigsegg feels more like a GT. “Our cars are also built to travel two-up,” says Koenigsegg. “There is a proper boot trunk, and even a space at the front in which to store the hardtop.” Like all other Koenigsegg’s, the Agera can of course be driven with the roof off. So, the million-dollarplus question: Bugatti or Koenigsegg? In terms of technology and control over the power, the Veyron. But for pure, visceral sensory overload, there’s nothing quite like the Koenigsegg Agera.

    Gulf News by Nick Hall. Agera Driven to the limit on the Dubai Autodrome:
    I can feel the car tugging to the outside of the circuit, under steering ever so slightly on a constant throttle. Of course you can balance the rear slip angle with a delicate right foot or push straight through into lairy, sliding oversteer with a hefty application of throttle, with the traction control switched off. But then with a turbo-powered car it makes sense to make it nose heavy. The brakes, meanwhile, are pin-sharp ceramics mated to six piston callipers and the car’s stability under heavy deceleration is a testament to the engineering throughout. The Veyron and this are two of the only cars that brake in a perfectly straight line without a hand on the wheel. The Koenigsegg doesn’t only fit the roof in that front end, it can even take golf clubs, a feat not matched by the Bugatti Grand Sport. It wins the practicality war by a mile.
    Specs:
    Engine = 5 liter V8
    Weight = 2932 lbs
    Aspiration = twin turbochargers
    HP = 940 = 1115 hp
    HP/Liter = 188 - 223 hp per liter
