The 2013 Buick Regal sedan delivers a premium, sporty driving experience while still achieving an estimated 36 mpg on the highway with eAssist. It's also a turbocharged performance touring sedan with power that is responsive yet responsible. Three propulsion choices balance efficiency and performance in the 2013 Regal lineup:

• Regal with eAssist light electrification technology with the Ecotec 2.4L engine with eAssist is the entry powertrain;

• Regal with Ecotec 2.0L Turbo, which makes 220 horsepower;

• Regal GS, a responsive, high-output turbo performance touring sedan with 270 horsepower and 295 lb.-ft. of torque.

Attention to detail complements the 2013 Regal's bold styling, with Buick design cues such as the waterfall grille, select use of chrome trim and excellent fit and finish of the exterior panels. Buick's signature portholes are located on the hood instead of the front fenders, and all Regal models sport a black chrome grille.

Regal's short rear deck and tucked-in body panels are characteristic of a contemporary sport sedan. Bold taillamps and intricate lighting elements underscore the car's attention to detail.

Regal GS features unique front and rear fascias, with the front fascia incorporating prominent, vertical air intake slots. The rear fascia has a pair of integrated, satin-metallic trapezoidal exhaust outlets.

Inside Regal, the feeling of flow and motion extends inside the car, where side panels flow uninterrupted into the instrument panel. Gauges and controls have the look of expensive sport timepieces and are lit with ice-blue LED lights.
