The Koenigsegg CCR is an automobile and supercar made by Koenigsegg. Designed and manufactured in Ängelholm, Sweden, it debuted at the 2004 Geneva Auto Show. It briefly held the world speed record for a production car.

The CCR is based on the Koenigsegg CC8S, featuring more power and higher performance. The improved-power engine of prototype was made possible by the use of a Lysholm twin-screw supercharger 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 Nˇm (678 ftˇlbf) at 5,700 rpm. However this car compares nothing to the Bugatti Veyron 16.4. This car is the one and only to have a horsepower guage in it. The Veyron has said to reach a top speed of 407 km\h (253 mp\h).

However, this supercharger is never used in production car. According to the official Koenigsegg book(ISBN 91-975178-3-6), the Lysholm twin-screw supercharger was lumbering and difficult to install in the mid-engined package. Production CCR is equipped with dual centrifugal compressors which is manufactured by Rotrex instead. It providing the same power, but lowering the peak torque point from 5,700 to 5,400 rpm.

Externally the CCR looks similar to the CC8S, but features a new side air-intake design, a tweaked headlight arrangement, a revised rear-end, larger brakes, more power and new front splitters for optimized downforce. Like the CC8S, the CCR is a two-seat coupe with a mid-engine, featuring large scissor doors that open by rotating up and forward.

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.

On a History Channel special on the CCR (Aug, 2006), Koenigsegg states that the base price for the CCR is approximately US$590,000.

The manufacturers claim the CCR is the fastest road car in the world, with a theoretical top speed of more than 385 km/h (240 mph).

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 387.87 km/h (241.01 mph) 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 CCR, driven by famous supercar test driver and veteran record breaker Loris Bicocchi. The car was clocked using Tag Heuer´s Splitmaster 650 with photocells stationary at the track, recording the average speed during 1 km.

The CCR took the record from the McLaren F1, which held the record for over 12 years of 386.7 km/h, set on the 9 km straight track at the VW Ehra facility in Wolfsburg, Germany. The CCR ran on the Nardō/Prototipo track, 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, a fairly sharp angle for the speed. On the same track, the F1 managed an unofficial record of 372 km/h.

In May, 2005 not long after the CCR claimed the record, a prototype of the long awaited Bugatti Veyron took the crown with a top speed over 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 November 2005 issue. However, the Bugatti set the record on the aforementioned official VW-test track in Ehra-Lessien with a 9 km unbroken straight, as opposed to the Nardō-track which is circular.
