The new three-cylinder engine is the second of several new engines and powertrains that will be launched by GM over the next few years. "This is a very lively and refined three-cylinder engine doesn’t compromise on driving fun.”Īs well as direct injection and variable timing for all 12 valves, the exhaust manifold is integrated into the engine head as a single casting, reducing parts count and making the engine more compact. "We’re confident customers will be pleasantly surprised by the results," Alt continued. "We also wanted to demonstrate that three cylinders can be just as refined as four or more." "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. GM's Opel 1.0-liter SIDI turbocharged three-cylinder engine - 2013 Frankfurt Auto Show In March, Edmunds reported that GM was considering a smaller, three-cylinder engine for a revised Volt to be released in 2016-though at that time, the substitution had not been officially approved. 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.
If the next Volt follows the powertrain strategy of the current model launched for 2011, its gasoline range extender may be an adaptation of a turbocharged engine used in various gasoline cars-but with its turbo removed.

Its 115-horsepower turbocharged 1.0-liter three-cylinder engine is the first in a new series of direct-injected gasoline engines that will appear not only in Opels but in other General Motors vehicles globally. market more than 30 years ago, the German brand and its British Vauxhall equivalent remain GM's largest in Europe.
