2003 Opel Vectra OPC

The Vectra concept car, developed by OPC and based on the GTS sport sedan, is powered by a new development of the 1.9 turbo-diesel available early next year in the Vectra and the Signum. While the standard 1.9 CDTI ECOTEC develops 150 bhp, the twin-turbo version increases this to 212 bhp and therefore has a higher specific power output than the V12 6.0-liter gasoline engine in the Ferrari Enzo. The Italian supercar develops 110 bhp per liter, the Opel Vectra OPC´s twin-turbo engine produces 112 bhp per liter.

Two electronically controlled turbochargers, with maximum boost-pressure of 3.0 bar, are key to the improved performance, enabling the 1.9-liter twin-turbo to drive as smoothly as a naturally-aspirated, large-displacement engine. Peak torque of more than 295 lbs-ft is available all the way up the engine-speed range from 1400 to 3500 rpm. Apart from the considerable power increase, one of the advantages of the twin-turbo principle is the engine’s low fuel consumption.
