Turbocharger is Back With High Fuel-Efficiency
Turbochargers are making a comeback. With new technologies and a need for fuel-efficient power, the auto industry is seeing a significant rise in turbos—with promises of more to come.Ford is particularly aggressive with the technology and plans to replace many of its V8 engines with twin-turbo V6s and use turbo four-cylinder engines to supplant V6s. The company has even coined a friendly name for its turbo engines—Ecoboost . Ford, however, is not alone. "We're going to see a lot more turbo engines," says Chris Meagher, GM's chief engineer for its Ecotec engines. Industry estimates peg global gasoline-turbocharger production to grow to around 3 million units by 2013. That's a sixfold increase in less than a decade.
Turbos have always been effective at increasing an engine's specific power, otherwise known as the output per displacement. A 2.0-liter turbo four-cylinder engine can easily match the power of naturally aspirated 3.0-liter V6, for example.
