The new torque-king of the four-cylinder gasoline engines in the European market comes from Opel. The two-liter turbocharged direct injection of solid aluminum brings a peak of 280 hp with the race, and a corresponding torque of 200 Nm per liter. This power output has the Opel Astra OPC itself from the competition to the segment of super sports car in its place. Here, the powerhouse is already its maximum torque at 2,450 rpm and holds one available at this rate until nearly 5,000 rpm 1 - Plenty of power for every driving situation.
To achieve this level of performance, the Insignia, Opel's engineers have used the two-liter gasoline engine with 250 hp has so modified that it has more than a sportier characteristic. A newly developed air intake feeds the turbocharger with the greatest amount of fresh air, while at the same time has grown more robust construction of the higher boost pressure and improves the durability of the loader. Maximum boost pressure is increased compared to the Insignia engine by 25 percent to 1.5 bar. The pressure build-up begins at 1,400 engine rpm, corresponding delay can be implemented, accelerator movements in vehement propulsion.
For such a powerful car has got it accordingly throaty exhaust note. In addition to the dull and masculine-sounding noise outside the OPC fans will feel it is reminiscent of the jet-like noise when accelerating from the previous models the midrange. A remarkable sound, especially if pending with forced movement of the shift from third to fourth gear.
