When General Motors debuted the 2012 Buick LaCrosse with eAssist technology at the Los Angeles Auto Show last year, the automaker told us that this new fuel-saving feature would quickly spread across many other models in its portfolio. Now, GM has taken the wraps off of the eAssist-equipped 2012 Buick Regal, which makes its official public debut at the Chicago Auto Show this week.
Most significantly, the addition of eAssist to the Regal's 2.4-liter inline-four powertrain means that the sedan is now capable of achieving 26 miles per gallon in the city and 37 mpg on the highway. Like the LaCrosse, the Regal eAssist uses a small, 15-horsepower electric motor to give assistance during acceleration, and when combined with things like regenerative braking and automatic start/stop, it means a substantial increase in fuel economy. It's not exactly Ford Fusion Hybrid impressive, but still quite good when you consider that the standard Regal only musters up 19/30 mpg ratings.
Unlike the larger LaCrosse, eAssist will not be the base powertrain for 2012 Regals. Buick has positioned the Regal eAssist to be part of larger family, which includes the Regal Turbo and upcoming GS. Model-specific changes over the base Regal include things like lightweight 17-inch alloy wheels (smaller than the standard Regal's 18-inch set), an eco mode for the air conditioning system, an eco gauge on the instrument panel and a powerflow readout in the seven-inch infotainment screen.
We'll be seeing the 2012 Regal eAssist live in Chicago this week, so stay tuned for more information.
