Flower Power - Koenigsegg's 1018 bhp biofuel-burning CCXR
March 3, 2007 When Bugatti unveiled the Veyron supercar, many people thought the ongoing contests for the world’s fastest, most powerful, and most expensive car in history were over – many motoring scribes wrote that due to increasing environmental concerns and the immense cost of developing a faster car, we’d never see the like of it again. It’s figure of 1001 bhp so completely eclipsed the previous best-of-breed cars such as the Koenigsegg CCX's 806 bhp that quite realistically, the game appeared to be over. Volkswagen spent so much money developing the Veyron, that although the car sells for UKP840,000 (US$1,630,000), when the all-up cost of development is added, they should be charging roughly UKP 5 million (US$9,700,000) per vehicle just to break even. No other manufacturer would be prepared to take a hit like that. Everything about the Veyron, from its 64 valve, quad turbocharger, W16 (16 cylinders in 4 banks of 4 cylinders) 8.0 litre engine, it’s dual-clutch DSG computer-controlled seven speed manual transmission, to its remarkable brakes are thoroughly engineered to enable the 1890 kg projectile to travel safely at over 400 km/h. Now Koenigsegg has surpassed the Bugatti’s power output, and is likely to threaten the Veyron’s 407 km/h top speed too. In a wonderful example of how a small goal-focussed team can achieve the seemingly unattainable, Swedish supercar manufacturer Koenigsegg has announced details of a new variant of its 806 bhp CCX which will run Biofuel. Due to the fact that the biofuel has higher octane and better cooling characteristics, the power has gone up 25% to 1018 bhp at 7200 rpm and torque is up 10% to 1060 nm at 6100 rpm, compared to the “standard” CCX’s 806 bhp at 6,900 rpm and 920 Nm at 5,700 rpm. Even though the low and exclusive production volume of Koenigsegg is hardly likely to have a measurable impact on the Co2 problem faced by global society, it is an impressive statement that a small company can afford to develop environmentally focussed solutions.
These two almost conflicting results are made possible due to the simple fact that the ethanol in biofuel firstly has the positive side effect of cooling the combustion chambers, as well as a higher octane value, well over 100 RON, which gives the high power.
It is natural to expect a substantial gain in power when optimising the engine for E85(biofuel) instead of Petrol. Still the actual gain obtained even surprised the enthusiastic engineers at Koenigsegg.
Following the long term strategy of Koenigsegg, all previous CCXs will have the possibility to be converted by the factory to accept the biofuel option and reap the performance and environmental benefi ts of this wonderful and eco friendly fuel.
The CCXR Biofuel upgrade has been developed in-house on the factory’s engine dyno by the skilled technicians at Koenigsegg, led by Christian Koenigsegg, Marco Garver and Anders Hoglund from the Koenigsegg partner company Cargine Engineering.
