"We not only set out to minimize fuel consumption and CO 2 emissions," said Matthias Alt, who's chief engineer for small gasoline engines at Opel. Nonetheless, GM expects the new three to be more refined than than the naturally-aspirated 1.6-liter fours it will replace-along with more torque and 20 percent better fuel efficiency. The engine block of the new 1.0-liter turbo three is entirely aluminum, reducing weight.

Opel gave very few specifics on the powertrain in the Monza Concept, aside from noting that the turbo 1.0-liter three in this case was powered by natural gas, which would further reduce its carbon emissions compared to running the same engine on gasoline. The current Volt engine is a 1.4-liter four that produces 85 hp, adapted from the 138-hp 1.4-liter turbo fitted to the Chevrolet Sonic subcompact and Cruze compact sedan.
