GM to Achieve Mileage Targets With Logic, Turbos

Instead of throwing all of its cash down the yawning maw of biofuel and hydrogen fuel cells, GM intends to get some quick fuel economy wins the smart way - with lower displacement and turbos. Automotive News (sorry, subscription required) is reporting GM will be following a strategy similar to Ford with its EcoBoost engines, namely using smaller engines in large vehicles, but bolstering them with the magic of exhaust driven compression. There's no speculation on when or in what we would see this strategy start to play out. We're on the torn here; big brutish V8's make us happy and can get decent mileage (see Corvette), but the fevered banshee scream of a turbocharged four banger is pretty rad too.
