Une Vectra OPC: 212 hp from 1.9-liter engine with fuel consumption of only 6.0 l/100 km


Le seul problème, c que elle est disponible qu'en Europe...

Si jamais ELLE *banghead* *banghead* *banghead* venait au canada, FU... la WRX!!

(Depending on the development objective, the twin-turbo can be designed either for high performance or for maximum efficiency in its consumption of fuel. Compared with a naturally aspirated diesel engine, power outputs can be raised by up to 50 percent without increasing fuel consumption. Alternatively, consumption can be reduced by as much as a quarter without loss of power. Opel has chosen the first route for the 1.9 CDTI twin-turbo engine used in the Vectra OPC study. This high-tech engine delivers a peak power output of 156 kW (212 hp) from just 1.9 liters displacement. The resulting specific power output of 82 kW (112 hp) per liter is a world record, not matched by any turbo-diesel in a standard production car.

Two-stage turbocharging combined with the latest common-rail fuel supply, variable multi stage fuel injection and twin charge-air intercoolers provide the increase in power and the maximum torque of 400 Nm, which is available over a wide engine-speed range from 1400 to 3600 rpm. With this engine the Vectra OPC accelerates from 0 to 100 in 6.5 seconds; the top speed is an electronically regulated 250 km/h. At 6.0 liters per 100 km in the European test cycle, fuel consumption is at the same low level as the production 1.9 CDTI units, and like these the twin-turbo engine can be fitted with a maintenance-free diesel particulate filter (DPF) that works without additives. Exhaust emissions already comply with the Euro 4 standard for new vehicles registered after January 1, 2006.
