The most powerful engine for all versions of the Opel Vectra and the Signum is an all-new 2.8-liter aluminum gasoline six-cylinder unit with a twin-scroll turbocharger for plenty of power in all driving situations. The sixty-degree V6 with variable valve control delivers 90 percent of its maximum torque of 330 Nm at 1500 rpm. Peak torque is provided across a wide range from 1800 to 4500 rpm. Driving performance with this engine is equally impressive: only 7.3 seconds are required for the zero to 100 km/h sprint and top speed (electronically limited) is 250 km/h - a new record for the Vectra.
