General Motors announced that Starting this fall, all new 2011 Buick Regals will have flex-fuel capability.
The Buick Regal currently comes with a naturally aspirated 2.4 liter four cylinder engine rated at 184 hp.
After the 2.0-liter direct injected turbo four starts arriving this summer, both engines will be able to run on either gasoline or E85 ethanol, making the turbo unit its first series production E85 turbocharged and direct injected engine. The engine was originally developed for the new Saab 9-5 which rides on the same Epsilon II platform as the Regal.
Jim Frederico, vehicle line director for the global midsize platfrom, said that combining direct injection and turbocharging will allow the new engine to get much closer to the volumetric fuel efficiency of gasoline while running on ethanol. Most previous naturally aspirated flex-fuel units register a 15 percent drop in efficiency when using ethanol (compared to gasoline).
The Buick Regal, which will use the 2.0 liter turbocharged powerplant, will start from $29,495, with both prices including a $750 destination charge.
