Under the hood

Unique with its all-four-cylinder powertrain, the Buick Regal relies on the excellent horsepower-per-liter ratio of the Ecotec engine family to deliver smart, on-demand performance that is also very efficient.

Both the standard 2.4L engine and the available 2.0L turbo use direct injection technology to optimize performance, reduce emissions and maximize fuel efficiency. The 2.4L is the same engine offered in the Buick LaCrosse, but in the smaller, lighter Buick Regal, it delivers more agile performance. The 2.0L turbo cements the sport sedan credibility of the Buick Regal, with on-demand power comparable to a V-6, but the inherent efficiency of a four-cylinder. To ensure responsive power across the rpm range, the 2.0L turbo uses a twin-scroll turbocharger that builds power quickly at lower rpm.

Distinct, uniquely calibrated six-speed automatic transmissions are paired with each engine. Both offer driver shift control that enhances the sporty driving feel of the Buick Regal.
