The Koenigsegg CCR broke the production road car speed record, achieving a new official top speed of 388 (387.87) km/h at Italy’s Nardo Prototipo proving ground.
A team of five Koenigsegg engineers and mechanics together with founder Christian von Koenigsegg ran, a technically standard Koenigsegg CCR in order to take the top speed record for productions road cars. The famous supercar test driver, Loris Bicocchi who is a veteran recorder breaker, drove the CCR.
The Koenigsegg CCR raised McLaren's previously unofficial mark of 372 km/h set at Nardo/Prototipo in 1993 with over 15 km/h. On top of this the CCR broke the official McLaren F1 record of 386.7 km/h, which was set on the 9 km straight line VW Ehra facility in Wolfsburg Germany.
A team of Nardo Prototipo technicians independently verified the speed of the CCR. The car was clocked using Tag Heuer´s Splitmaster 650 with photocells stationary at the track, recording the average speed during 1 km.
Nardo Prototipo is a circular track with a circumference of 12.5 km. This means that the car is driven in a constant turning motion, which makes the exercise and speed even more impressive. The steering wheel at this speed is kept at around 30 degrees of constant angel, which equivalates to a sharp corner for the speed.
The constant turning motion of the car creates extra friction on the tires. This extra friction overcomes the extra horsepower that was needed for further acceleration. The maximum speed was reached at around 6790 rpm, which is not equivalent to the maximum hp level, which is at a higher rpm.
With this verification of speed, Christian von Koenigsegg is even more confident that the Koenigsegg CCR is capable of reaching its projected top speed of 395 km/h, or more, in a straight line.
