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. |
