This well-honed and satisfying sports sedan has a European feel, thanks to its Opel roots. It is the antithesis of the whitewall-tired Buick of old. With its agile handling, quick steering, and a taut, steady ride, the Regal is one of Buick's best offerings. The 259-hp, 2.0-liter turbo four-cylinder delivers strong performance and 24 mpg overall. High-quality materials are used throughout the cabin. The front seats are firm and supportive, though the rear seat is quite snug. The large trunk is a bonus. Infotainment system controls are mostly simple, and all-wheel drive is available on all trim lines. Overall, this is a highly capable yet understated car. The GS is a sportier version with a tauter suspension. A redesign is imminent.
