gm to introduce turbocharged 1.4-liter engine for small u.s. cars

It seems that GM has found the best solution to improve fuel economy: small engines with turbochargers. Starting 2009, the company will introduce a turbocharged 1.4-liter gasoline engine for small U.S. cars. First to use this engine are the Chevrolet Cobalt and Saturn Astra. Same engine could be used in mid-sized vehicles, too.

"You’re going to see turbocharged four-cylinders in vehicles that no one could have ever imagined that they would be in," said GM engineering chief Jim Queen.


Queen did not indicate where the engines would be made or predict their fuel economy.

The 2008 Cobalt powered by a 2.2-liter engine gets 33 mpg highway and 24 city. The smallest GM model in the States is the Korean-built Chevrolet Aveo that is powered by a 1.6-liter. The Saturn Astra is powered by a 1.8-liter engine.

Turbochargers could cost GM $200 to $450 per vehicle depending on the system’s sophistication, said Jim Hall, director of industry analysis at 2953 Analytics in suburban Detroit.
