04. Koenigsegg Agera R – Top Speed 260 mph/ 418 kmh

The Agera R made its debut at the March 2011 Geneva Motor Show—with a Speed Racer livery theme, and special Michelin tyres. It can accelerate from 0–100 km/h (0–62 mph) in 2.8 seconds and reach a theoretical top speed of 439 km/h (273 mph). The Agera R has a drag coefficient of Cd=0.37, or Cd=0.33 at high speed due to its adaptive rear wing, while producing 300 kg (660 lb) of downforce at 250 km/h (155 mph). This adaptive rear wing system is lighter than conventional hydraulic/electrical adaptive systems, and has the unique ability to compensate for head/tailwind due to its spring-loaded design. Furthermore, the pylons holding the wing play not only a role in the Agera R’s aerodynamic performance, but also assist in extracting hot air from the engine bay.

On 2 September 2011, 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 mph) in 14.53 seconds, and 0-300-0 km/h in only 21.19 seconds. The braking performance required to maintain this record is enabled in part by the Agera’s stability, demonstrated by Koenigsegg’s test driver and drivetrain technician Robert Serwanski, who was recorded by passenger Rob Ferretti (founder of the group “Super Speeders”) braking from 300 km/h to 0 without holding the steering wheel.

The Agera R can produce lateral cornering forces of 1.5 G, due to a combination of mechanical balance and high levels of grip from the specially developed Michelin Supersport tyres.

The Agera R was featured prominently in the movie Need for Speed and in Criterion’s Need For Speed: Most Wanted (2012) and Need for Speed: Rivals (2013) video games.
