The Regal is the sportiest model in Buick's line-up, built in Canada but engineered and designed in Europe. A 259-horsepower, 2.0-litre turbocharged 4-cylinder engine mated to a 6-speed automatic is standard, while a fuel-efficient, 182-horsepower, 2.4-litre eAssist engine is optional, as is AWD. A Sport Touring trim is new for 2016, while the most potent variant is the Regal GS, which benefits from an adjustable sport suspension, bigger brakes and more aggressive styling, in addition to an optional 6-speed manual gearbox.
