2013 Buick Regal Engine Lineup Detailed
eAssist will boost the standard economy of the 2013 Regal to 36 mpg highway, which is impressive for a car of this size. This is achieved through the stop/start function that shuts the engine when you’re at the lights, regenerative braking that gathers and stores energy that would otherwise be lost during braking, and an electric motor assist that reduces the gas engine’s work during acceleration or on inclines.
“With eAssist, Buick is redefining what a ‘conventional powertrain’ means to customers,” said eAssist global chief engineer Stephen Poulos. “It changes the fuel economy – but not the experience – for the 97 percent of new car buyers who aren’t buying hybrids.”
“It takes advantage of the best parts of a hybrid, and eAssist is now standard equipment for Regal,” said Poulos. “These new functions happen seamlessly, a requirement for Buick drivers who demand a refined driving experience. They’ll really only notice a difference at the pump.”
If performance is what you’re after, the two other engines on offer are advanced 2.0-liter turbocharge Ecotec units, offering 220 hp in the case of the Regal Turbo and 270 hp for the Regal GS. Now for 2013, the Regal GS is available with an automatic gearbox, which offers the same sort of performance as the manual.
