The Buick Regal lineup gets considerably more fuel-efficient for 2013—with an EPA rating of 36 mpg highway that beats most other sedans its size.

GM has dropped the base 2.4-liter Ecotec direct-injected four-cylinder engine on the 2013 Buick Regal and is instead making its eAssist mild-hybrid powertrain standard.

Eassist, which GM calls “light electrification technology,” uses a small lithium-ion battery pack and electric-motor system to assist the four-cylinder engine especially at low speeds, working together with a six-speed automatic transmission.

According to the U.S. EPA, the 2013 Buick Regal eAssist earns fuel economy ratings of 25 mpg city, 36 highway. Those are the same figures earned by the larger LaCrosse sedan, which already got the eAssist combination as its base powertrain for 2012. But they're much better than the 2012 Buick Regal, which with the previous base engine had achieved just 19 mpg city, 31 highway.

Pricing of the 2013 Buick Regal hasn't yet been released at the time of writing, but we're curious to see how GM wraps it in. The eAssist system had been a $2,000 option on 2012 Regal base and Premium models, with the 2012 Regal starting at $27,940.

Step-up 2013 Regal Turbo models remain powered by a 220-horsepower, 2.0-liter four-cylinder engine and six-speed automatic transmission.

The high-performance Regal GS remains powered by a 270-horsepower high-output version of the 2.0-liter turbocharged four-cylinder engine, along with a host of performance upgrades, including four-piston Brembo front brake calipers. But in addition to the six-speed manual gearbox, there's now a six-speed Aisin automatic transmission, including Driver Shift Control. The automatic won't slow things down either; 0-60 mph comes in just 6.7 seconds—the same as the manual version.

Be sure to read our full review of the 2012 Buick Regal, as well as this driving report on the LaCrosse with eAssist, for more information and insight.
