Buick Makes eAssist Standard on Compact Regal

Also introduces automatic option on sporty GS.

The 2012 Buick Regal shown with Regals past.

Buick will drop the conventionally-powered I-4 version of its Regal model, making the “mild” hybrid eAssist the standard powertrain for the compact sedan starting in 2013.

That’s the same strategy that the maker has taken with the midsize Buick LaCrosse.  In the smaller Regal, the gas-electric driveline delivers as much as 36 mpg on the highway, according to the EPA.

Meanwhile, the mid-luxury General Motors brand has announced it will introduce a new automatic gearbox for the sporty, turbocharged version of the compact sedan, the Regal GS.  Until now, it has only been available with a six-speed stick, a sales-limiting factor in today’s U.S. market.


Buick Regal to Get New eAssist Drivetrain

At 37 mpg, a 25% mileage bump.

The eAssist system bumps Regal mileage to 37 mpg on the highway, 26 around town.

The new Buick Regal, currently an also-ran in the midsize mileage race, is about to get back in the game.

The maker will give Regal the same eAssist hybrid driveline used by the bigger Buick LaCrosse, it will formally announce at the Chicago Auto Show, this week.  That technology will bump fuel economy upwards by an estimated 25%.

While the Regal will still lag behind Ford’s 40+ mpg Fusion Hybrid, the Buick offering will still get a respectable 37 mpg on the City, according to preliminary estimates, and 26 mpg in city driving.

And that’s a big improvement from the conventionally-powered sedans current 19 City/30 Highway rating.

The eAssist driveline is what generally is known as a “mild hybrid,” or “mybrid,” though General Motors prefers the term, “light electrification.”
