The 2017 Buick Regal is a midsize luxury sedan available in four trim levels: the base Regal 1SV, Turbo, Premium II, and the top-of-the-line GS. All trims come standard with a turbocharged 2.0L four-cylinder engine producing 259 horsepower mated to either a six-speed automatic or manual transmission. The GS trim also comes with an exclusive option of a 3.6L V6 engine offering 310 horsepower. The Regal's comfortable ride quality is a standout, as is its quietly competent handling. Available features include an 8-inch touchscreen with the IntelliLink infotainment system, Apple CarPlay and Android Auto, a premium Bose sound system, and key safety features such as adaptive cruise control, blind-spot monitoring, and forward collision alert. The 2017 Regal represented the last model year for the car's fifth generation, before a full redesign for 2018.
