GM will use Stop-Start technology on future cars to reduce fuel consumption

Article by Christian A., on April 27, 2011

General Motors’ future cars will be fitted with Stop-Start technology to cut their fuel consumption, Detroit News stated in a recent report. The Stop-Start Technology works by shutting down the engine if the car completely stops. It’s restarted instantly as soon as the driver lifts the foot off the brake pedal -- on automatic gearbox cars.

But for the manual transmission ones, the engine turns back on when the clutch is engaged. GM’s system has been dubbed eAssist.

It will be offered as standard on all 2012 versions of the four-cylinder engine that power the Buick LaCrosse sedan. On the 2012 Buick Regal, this system is offered as an option.

The carmakers that have already started to use this technology are Mercedes-Benz, BMW, Porsche, Mazda, and Peugeot. Ford is introducing a similar system for its models within the next few years. Steve Poulos, chief engineer for eAssist, said that this is called a 'light electrified' technology.

When it comes to overall cost, it offers a lot of value compared with full hybrids. He added that this may become its base powertrain. Poulos claimed that the 2.4-liter eAssist engine with a six-speed automatic transmission on the LaCrosse model can achieve 25 mpg (9.4 liter/100 km) in the city and 37 mpg (6.3 liter/100 km) in the highway.

The eAssist system can raise its fuel efficiency by 25% compared to the 2011 LaCrosse model. General Motor’s eAssist engines feature fuel injection, which enables the power unit to turn on in only 200 to 300 milliseconds. Aside from the 180 hp gasoline engine, it will also get a 115-volt lithium-ion battery and a 15-kilowatt motor-generator.
