Koenigsegg CCR
From Free net encyclopedia
The Koenigsegg CCR is an automobile made by Koenigsegg. Designed and manufactured in Ängelholm, Sweden, it debuted at the 2004 Geneva Auto Show.

Overview
The manufacturers claim that their car is the fastest road car in the world with a theoretical top speed of more than 385 km/h (240 mph). The car reached a top speed of 388 km/h (241 mph) on February 28, 2005 breaking the world speed record for a production car (the previous record holder was the McLaren F1, which had a top speed record for over 10 years of 240.14 mph). In May, 2005 not long after the CCR claimed the McLaren's record as its own, the honour was given to a prototype of long awaited Bugatti Veyron which obliterated the previous record with a top speed of 400 km/h (249 mph). The final production model of the Veyron reached a speed of 407.5 km/h (253.2 mph) in the hands of Car and Driver in their January 2006 issue.
Based on the Koenigsegg CC8S, the CCR was the top-end car produced by Koenigsegg. The new Koenigsegg CCX is now the top-end car. It retains all the features of the CC8S, and has a new side air intake design, a tweaked headlight arrangement, a revised rear, bigger-sized brakes, more power and new front splitters for optimized downforce.
The improved-power engine was made possible by the use of a unique Swedish Lysholm twin-screw compressor and a new titanium exhaust system. This takes the power output to a maximum of 806 hp (601 kW) at 6,900 rpm. Torque is also distributed evenly, and peaks at 920 N·m (678 ft·lbf) at 5,700 rpm.
The final version of the CCR is equipped with twin Rotrex centrifugal compressors. Boost pressure has been increased from 120 kPa to 140 kPa (1.2 bar to 1.4 bar). It shows same maximum power (806 hp) at 7,000 rpm, same maximum torque (920 N·m) at 5,400 rpm. (Note: This information of performance is partially updated in their official page.)
To honour the Swedish Fighter Jet Squadron No. 1, (Johan röd) which had occupied the current facility of Koenigsegg, the CCR is adorned with a symbol of a ghost, the symbol of the squadron.
Testing history
On February 28, 2005, at 12.08 local time, 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 CCR was driven by famous supercar test driver and veteran recorder breaker Loris Bicocchi.
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 angle, 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 power 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.
McLarenF1 top speed is 372 km/h at Italy’s Nardo Prototipo proving ground and 386.7 km/h on the 9 km straight line VW Ehra facility in Wolfsburg Germany. Koenigsegg CCR top speed is 387.87 km/h at Italy’s Nardo Prototipo proving ground(15 km/h more than McLaren F1) = 387.87 + 15 = 402.87 km/h on the 9 km straight line VW Ehra facility in Wolfsburg Germany.
