General Motors said today that powertrain engineers have significantly upgraded the 2.0L inline 4-cylinder in the 2011 Buick Regal Turbo to be capable of running on any blend of gasoline or E85 ethanol. The Buick Regal Turbo now joins more than than 5 million flex-fuel models that GM has produced over the last 15 years and helps the Detroit automaker reach its goal of offering more than 50 percent of its production in flex-fuel models by the end of 2012.

“Since ethanol requires a richer air-fuel mixture than gasoline, flex-fuel engines need higher flow-rate injectors,” GM said in a statement. “However, a flex-fuel engine can potentially have any combination of gasoline or up to 85 percent ethanol in the tank, so a sensor in the fuel system measures the blend in real-time.”

Other changes, besides making the turbo engine flex-fuel capable, include a new precision sand cast aluminum cylinder block that provides better durability while transmitting less noise and vibration than lost foam casting used previously.

Refresher: The 2011 Buick Regal is available in two options including a 182-hp 2.4L 4-cylinder and a 220-hp 2.4L 4-cylinder turbocharged. Estimated fuel-economy for the non-turbocharged model comes in at 20/30 mpg (city/highway). The 2011 Regal will be built in Russelsheim, Germany, giving it the handling and dynamics of a premium European sport sedan. Prices start at $26,995 for the CXL trim.
