The new GS also allows drivers to adjust suspension settings and steering sensitivity between three modes: standard, sport and GS.
Visually, the car features unique front and rear fascias, with the front fascia incorporating prominent, vertical air intake slots and specific grille treatment – with the vertical elements accented in a satin-metallic finish.
In order to enhance the sporty feeling, the GS benefits from a lower ride height than other models and aggressive 19-inch, 5-Twin Spoke alloy wheels and all-season tires (20-inch, 5-Twin Spoke polished alloy wheels with performance tires are optional).
Interior highlights include a racing-inspired, flat-bottom sport steering wheel and metal sport pedals, along with leather-appointed 12-way power-adjustable sport driver and front passenger heated seats, which include four-way power lumbar. The black interior is accented with satin-finish elements on the instrument panel, steering wheel and console, while the instrument panel glows white when the driver engages the GS mode of the Interactive Drive Control System (IDCS).
"Built on the performance foundation of the Regal, the Regal GS was designed as an even sportier expression of responsive performance and style," said John Schwegman, vice president of Buick marketing. "The driving experience is powerful and spirited; and the GS represents the next entry in Buick's product renaissance."
