Cars pro The Koenigsegg CCX - Auto pro Koenigsegg CCX change on the CCXR is a slightly modified engine that can accept E85 or E100 ethanol fuel, along with regular unleaded gasoline. Koenigsegg made a few other minor tweaks such as modifying the fuel injectors, upgrading fuel lines, and most importantly, increasing the supercharger boost levels. Although seemingly minor changes, the resulting improvements are staggering. The Rotex twin-supercharged 4.7 liter V8 pushes out 1,018 horsepower at 7,200 rpm and 740 lb-ft of torque at 6,100 rpm. That's Veyron Super Sport territory in HALF the cylinders and displacement. These are figures that only the Zenvo ST-1 has also been able to encroach upon in recent years with a similar platform. The additional power helps the Koenigsegg CCXR to go from 0-60 in 3.1 seconds and on to an estimated 250+ mph top speed. That biofuel overhaul makes the CCXR 0.1 second faster to 60 than the CCX and it has 212 more horsepower and 47 more ft-lb of torque.
