Fact #852 December 22, 2014 Turbocharged Engines Account for 64.7% of all Four-Cylinder Gasoline Car Engines in 2014

You are here

As auto manufacturers pursue greater fuel economy, models are increasingly being offered with smaller displacement engines that consume less fuel. In order to meet performance expectations, turbocharging is used to increase power output of the smaller engines. Many midsized sedans that were previously installed with 6-cylinder engines are now only offered with a turbocharged 4-cylinder engine that delivers improved fuel economy and performance that meets or exceeds that of the old 6-cylinder engines. Light trucks have seen a similar trend where 8-cylinder engines are being replaced by turbocharged 6-cylinder engines.Turbocharged engines are now 15.7% of all light vehicle engines produced.
