GM working on an all-new Ecotec 2.0-liter turbo engine

Sources say that General Motors is working on an all-new Ecotec 2.0-liter turbo engine. It was in 2006 when the 2.0-liter displacement with the LNF made its debut. It wasn’t very long before the Ecotec four-cylinder with its 260hp and 260 foot-pounds of torque caught on. From that point, the 2.0-liter has become a feature that was heavily discussed.

The LNF is no longer used in any of its vehicles but a variation remains in production for the Buick Regal Turbo and Regal GS in North America as well as the Opel Insignia in Europe. The name LHU is seen on the 2.0-liter mill in all three applications.

When used in the Regal Turbo and Insignia, the engine offers 220hp and 258 foot-pounds of torque. On the other hand, the Regal GS delivers 270hp and 295 foot-pounds of torque. GM denies several reports that the 2.0-liter turbo in the Regal GS is the "new" 2.0-liter. For the Regal GS, GM has increased the boost level on the turbocharger and raised exhaust flow to result to the higher power figures.

As there are only slight changes made, it is referred as the LHU’s high output version. In 2012, the engine will debut in the upcoming Cadillac small sedan, codenamed ATS. Insiders say that this engine will be the V-6 replacement for the all-new Chevrolet Malibu.

The company has yet to announce the exact power figures for the new 2.0-liter turbo but sources say that it’s expected to offer between 270 and 280hp, according to GMInsideNews. The engine is supposedly an all-new design and is included in the new family of Ecotec four-cylinders at GM.

It joins the Ecotec 2.5-liter, which is also used to power the 2013 Chevrolet Malibu. Last August, GMI confirmed that only four-cylinder engines will be used on the future GM midsize sedans. Reports about the new 2.0-turbo imply that the transfer of the V-6 in the GM midsize sedan lineup isn’t really much of an issue after all.
