On Wednesday from Paris, Automotive News' GM reporter added to the unofficial statements that the next-gen Volt will get a three-cylinder 1.0-liter turbo, and he was there to see an Opel/Vauxhall Corsa which got it first.



In a blog post titled “What the new Opel Corsa and next-gen Chevy Volt have in common,” Mike Colias cited sources – plural – saying the 1.0-liter which is part of a new family of small, efficient Ecotec gasoline engines GM recently introduced , will be first seen stateside in the Volt.

“The Volt should be the first U.S. car to get the three-banger when the next generation of the plug-in hybrid goes into production in late 2015, sources have said. It's likely to go into the redesigned Chevy Spark as well, also scheduled for a late 2015 or early 2016 launch,” wrote Colias.

He went on to conjecture he’d not be surprised to see it in the next redesigned Sonic and even the next Cruze to match similar 1.0-liter entries by Ford.



Engines that meet goals in the US, European, and even other markets, Colias said, should help CEO Mary Barra meet GM's strategic goals also released yesterday. (GM's press release did not once contain the word "electric, plug, Voltec, or hybrid.)

Consolidating engines across global markets also helps GM negotiate better deals requiring a far larger number of units with suppliers, Barra was quoted as saying in 2013 while still global product chief.

In a report I from March on the new Ecotec engines, AN wrote these will range from the small 1.0 to 1.5 and be high tech.



 

The new Ecotec engines with aluminum block and heads will have:

• Double overhead cams with four valves per cylinder.
• Water-cooled exhaust manifolds that enable faster warm-ups and the car’s heater to deliver warm air quicker.
• Variable oil pumps that save energy by delivering only the amount of oil the engine needs based on speed, load and temperature.
• Piston cooling jets to control piston temperatures.
• Variable valve timing, which adjusts the opening and closing of the intake and exhaust valves and enables the engine to run more efficiently at different speeds.

And, said AN in March as well:

“Depending on the market and the application, some engines will be offered with direct fuel injection and turbocharging, which enables small displacement engines to deliver far more power,” it wrote. “The engines also will be used in plug-in hybrids, such as the Chevrolet Volt and Cadillac ELR.”
