Vacaville GMC Buick with a 2013 Buick Regal in Vacaville

http://VacavilleGMC.com/VehicleSearchResults 866-593-1568 The story of the 2013 Buick Regal really revolves around its engines. The Regal starts out with a 2.4-liter engine backed up by a mild hybrid system ("eAssist"), which has become familiar as a simple stop-start system for the engine. This boosts city fuel economy to a useful 25 mpg, while the 36 mpg achieved by this engine in highway mode makes the Regal superior to every other midsize sedan.
