At this vehicle already are noticeable influences of the acquisition by GM. The engine originates from there together with a 1.8-liter six-cylinder. Now more attention is paid to efficient production. Thus, both engines e.g. have the same crankshaft drive up to the crankshaft and the same valve-train assembly up to the camshaft. There are still standing valves, but compared to their German competitors are both (each different) civilized. Interesting is their long-stroke laying, which pretty good driving power causes at low speed.
The Opel is 1.2 because of its low cost as a 'car for the people'. By it are produced more than 100,000 pieces for the first time in Germany.
