Chevy Volt Could Use Turbocharged 2.0-Liter Ecotec in 2014

2012 Chevy Volt

Inside EVs reports that, come 2014, the Chevy Volt's range extender will be a turbocharged 2.0-liter Ecotec engine.

InsideEVs.com reported earlier this week that the 2014 Chevrolet Volt will ditch its 83-horsepower 1.4-liter range-extending engine in favor of GM's 2.0-liter turbocharged Ecotec four-cylinder engine. The website attributed the news to an unidentified source "inside the company (GM)."

The source said the Volt's current 1.4-liter engine is "definitely not" the unit that will reside between the fenders of the 2014 Volt. The 1.4-liter four cylinder, when mated to the Volt's electric motor, pumps out a combined 149 horsepower and 273 pound-feet of torque. But more power is in the Volt's future.

InsideEVs.com said that it's almost certain that the 2014 Volt will feature a turbocharged 2.0-liter Ecotec four-cylinder with an output of 220 to 270 horsepower. This engine, which is found in the current Fisker Karma, is much more potent than the current 1.4-liter and far more advanced. However, upgrading to the 2.0-liter will almost certainly require modifications to the Volt, including an upgraded electric motor and perhaps even significant revisions to the rest of the Volt's advanced powertrain.

2.0-liter Ecotec

GM's 2.0-liter Ecotec turbocharged four-cylinder engine is used in several of the automaker's existing vehicles.

Here's a snippet of how GM describes its 2.0-liter Ecotec engine:

“Our continuously variable valve timing is tuned to work in tandem with direct injection and twin scroll turbocharging to achieve optimum fuel economy, lower emissions, and instant performance when needed. Having 295 pound-feet of torque available over a wide range of engine speeds makes for a very exciting driving experience.”

As expected, General Motors "refused to confirm or deny truth of the news leak of the 2014 engine, citing the usual policy of not commenting on future product."
