The GS adds several handling and appearance enhancements to the Regal, even though it now shares its engine with the rest of the range. A six-speed automatic is standard, although a six-speed manual is a no-cost option. Front and rear parking sensors are included, as is the HiPer strut front suspension system, Brembo front brakes, dual stainless steel exhaust tips, GS-specific front and rear lower bumper treatments, and 19-inch alloy wheels.
Inside, there's an 8-inch configurable driver information display and sport front bucket seats. Options include 20-inch alloy wheels, all-wheel drive (but only with the automatic transmission) and a moonroof. The Driver Confidence 1 and Driver Confidence 2 packages are also optional on the GS.
