Koenigsegg Agera R

The 2013 model features new Aircore hollow carbon fiber wheels, upgraded power and enhanced aerodynamics. The Agera R has an incredible top speed of approximately 440 km/h (273  mph).
The Agera R is the only roadster Hypercar with a detachable and stowable hardtop, bringing the best of two worlds. This in combination with 120 litres of luggage space, truly combine extreme performance with everyday usability.
The Agera has a body made from impregnated carbon fiber/kevlar with lightweight reinforcements. The car’s hardtop roof is stowable under the front hood lid. The chassis is also made out of carbon fiber with an aluminum honeycomb that comes with integrated fuel tanks for optimal weight distribution and safety. The rear wing is electronically adjustable with auto setting or manual control in order to have as little compromise as possible between low drag and down force, depending on situation and mood. The Agera comes with forged aluminum wheels with center locking nuts, measuring 19″ on the front and 20″ on the back and wrapped in a set of Michelin Super Sport tyres that can be used with speeds of up to 260 mph (420 km/h). Other highlights include the trademark Koenigsegg doors, a new traction control system, LED lighting, blue hood stripes that continue on through the cockpit of the car and a custom interior with a new “Ghost light” lighting system, which uses carbon nanotubes in a unique configuration to shine through the car’s aluminum buttons.
The Agera is powered by an in-house developed 5.0-litre twin-turbocharged V8 engine which produces 940 hp (701 kW) at 6900 rpm and 1,100 N·m (810 lb·ft) of torque at 4000 rpm. Total weight of the engine is only 197 kg (434 lb) thanks to a carbon fiber intake manifold and the aluminium construction. The transmission is a 7-speed dual clutch with paddle shifters. It is the first dual clutch transmission to feature only one input shaft. The second clutch slows down the input shaft during up shifts in order to reduce the time it takes to synchronize the next gear, resulting in faster shift times. Most notably, the transmission weighs only 81 kg (179 lb).
