In March 2008, two models - The CCX Edition and the CCXR Edition - were launched at the Geneva Motor Show.[23] Both models are fitted with a remapped, 4.8 liter twin-supercharged Koenigsegg engine. The engine tune in the CCXR Edition is more powerful than that of the standard CCX, developing 1,018 bhp (759 kW) at 7000 rpm and 797 ft·lb (1,081 N·m) of torque at 5600 rpm. The CCX Edition develops 888 bhp (662 kW) at 7000 rpm and 679 ft·lb (921 N·m) of torque at 5800 rpm. In total the Edition produces over 772 lb (350 kg) of downforce at 155 mph (249 km/h).[24]
The Edition CCXR and CCX are more track oriented compared to the standard models, being equipped with stiffer springs and anti-roll bars, reset dampers and a lowered chassis. The Edition CCXR and the CCX also feature a fully visible carbon body, a large adjustable rear wing, larger front splitter and side strakes and a unique forged wheel design.[25]
The interior is also reworked and features: color matched leather carpets, Koenigsegg Edition side step plates, Edition chronograph instrument cluster, a new Edition only layout for the center console control panels, and features a special version of the Koenigsegg Chronocluster including a redesigned center console. All other extra equipment for the Koenigsegg Edition CCXR and CCX comes as standard: carbon wheels, special interior trim and color, rearview camera, Satnav or Bluetooth, amplifiers, complete Inconell exhaust system.
