Koenigsegg Agera

The Koenigsegg Agera is a mid-engined sports car made by Swedish car manufacturer Koenigsegg as of 2011. It is a successor to the Koenigsegg CCX/CCXR. The name Agera comes from the Swedish verb 'agera' which means "to act” or "to take action".
It was named Hypercar of the Year in 2010 by Top Gear

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 aluminum 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).

The Agera R made its debut at the March 2011 Geneva Motor Show — with a ‘Speed Racer' livery theme, special Michelin tires and a Thule Roof Box – although its existence as a production car was already announced prior to this. It is in essence a special edition Agera, which runs on biofuel, rather than petrol.It can accelerate from 0–62 mph (100 km/h) in 2.9 seconds and reach a theoretical top speed of approximately 275 mph (442.569 km/h).
The wing on the Agera R differs from the standard car in that it isn't electronically adjustable, but instead uses the pressure of the wind created at high speeds to force the wing downward and reduce wind resistance. The system is not only lighter than conventional hydraulics, but also smarter since it is able to compensate for headwind or tailwinds instantly. The design is thought out so well that even the pylons holding the wing up are useful.[citation needed] They are shaped in a way that helps to extract air from the engine bay towards the rear of the car.

On 2 September during test sessions in Ängelholm the Agera R broke six world land speed records for a production car, including 0–300 km/h (0–186.4 mph) in 14.53 seconds, surpassing the previous record of 14.6 seconds set by the Bugatti Veyron. The Guinness Book of Records is yet to confirm the results, although all data was measured and collected by a third party with the officially accepted Racelogic VBox performance recorder.A modified Agera R can produce lateral cornering forces of 1.6 g, thanks to grip from the Michelin Super Sports and a special setup focused on cornering speed.
