This year´s Essen Motor-Show (November 28 to December 7, 2003) will host a spectacular world premiere. The Opel Performance Center (OPC) is presenting an ultra-sporty concept car based on the Opel Vectra GTS. Featuring innovative twin-turbochargers, the 1.9-liter diesel produces 156 kW (212 hp) and peak torque of more than 400 Nm from as low as 1400 rpm. With this engine the Vectra OPC needs no more than 6.5 seconds to sprint from zero to 100 km/h. Top speed is limited electronically to 250 km/h, while fuel consumption in the European test cycle is only six liters per 100 kilometers. With this powerful yet economical, high-performance common-rail injection engine, Opel demonstrates again its renewed diesel expertise.
Besides the Vectra OPC concept, Opel is also showing its current motorsport program in Essen – the Nürburgring-24-Hours-winning Astra V8 Coupé; the Opel 2.0-liter-powered winner of the inaugural Formula 3 Euroseries; and a Corsa S 1600 junior world rally car, similar to the example that won this year's hotly contested British S 1600 rally championship. A big display of production performance cars, including the Speedster Turbo, Zafira OPC and the all-new Astra, completes the exhibits on Opel's stand in Hall 3.
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 110 kW (150 hp), the twin-turbo version increases this to 156 kW (212 hp) and therefore has a higher specific power output than the V12 6.0-liter gasoline engine in the Ferrari Enzo. The Italian supercar develops 80.8 kW (110 hp) per liter, the Opel Vectra OPC´s twin-turbo engine produces 82 kW (112 hp) 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 400 Newtonmeters 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. Whereas additional power is often coupled with higher fuel consumption, the Opel twin-turbo in the Vectra OPC consumes no more than the standard production engine (6.0 l/100 km in the European test cycle). The exhaust emissions of the Vectra OPC are also below the Euro 4 limits that come into force as of January 1, 2005.
The concept car shown in Essen features the Arden blue typical of OPC products, a lowered body with aerodynamic accessories and 19-inch alloy wheels with 235/30 tires. The interior is largely trimmed in blue leather. In view of the car's high performance potential, the spring and shock absorber settings have been modified and an even higher-performance brake system installed.
