Big changes are on the horizon for the Regal. The GS body style takes a stark departure from the classic sedan look with an edgier profile, a rear lip spoiler, and 19-inch alloy wheels. It gets some muscle under the hood with its 310-horsepower, 3.6-liter V6 power plant with a nine-speed automatic transmission and all-wheel drive. It gets plenty of upgrades too with sport exhaust, Brembo front brakes, three driving modes, and adaptive damping suspension. The Regal Sportback is new for this model year. This vehicle has a presence with its sleek profile. The base build has a 250-horsepower, 2.0-liter, four-cylinder engine with a nine-speed automatic transmission and front-wheel drive. It comes in five trim levels with an all-wheel-drive option available with the premium editions. The cabin is roomy and well-equipped with OnStar Guidance communication, two USB ports, remote keyless entry, and Android Auto and Apple CarPlay available out-of-the-box.
