2011 Koenigsegg Agera R


In 2010 Koenigsegg presented a pre-production version of the Koenigsegg Agera. Since then the pre-production car and several test mules have continued the Agera development program. 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.

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.
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 Koenigsegg Agera R format the engine has a peak torque of 1200 Nm over a 3300 rpm rev range, showing great flexibility.

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 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 392×36 mm and 380×34 mm ventilated and drilled ceramic discs, for unparalleled braking performance and zero fade regardless of track or road condition.
