The 2018 Buick Regal Sportback is a five-door mid-size vehicle and marks the beginning of its sixth generation. Two engine options are available: a 250-hp 2.0L turbo four-cylinder in either FWD or AWD, and a 310-hp 3.6L V6 available exclusively with AWD and a nine-speed automatic transmission (GS trim). This year marks the introduction of the hatchback model, which offers generous cargo space. Its infotainment system is modernized, coming standard with a 7.0-inch touchscreen with Apple CarPlay, Android Auto, and 4G LTE with a mobile Wi-Fi hotspot. Key safety features include lane-keep assist, forward-collision warning, and adaptive cruise control.
