Inside, the Regal GS varies from the standard Regal by featuring a completely jet black
interior, including the pillars and headliner, sport shifter for the six-speed manual
transmission and a suede-covered, flat-bottom steering wheel reminiscent of those used
in international racing series. The instrument panel glows ice blue when the driver
engages the sport mode of the Interactive Drive Control System (IDCS).
Turbocharged AWD performance
Power for the Regal GS comes from a high-output 2.0L Ecotec turbocharged engine with
direct-injection technology. It is based on the engine that will be offered on Regal CXL
models later this summer, but the engine and turbocharger are tuned to deliver greater
boost pressure in the GS. The output is estimated at 255 horsepower (190 kW) and 295
lb.-ft. of torque (400 Nm).
The engine is mated to a six-speed manual transmission that directs torque to an
adaptive all-wheel-drive system calibrated for performance driving. An electronic, limited-
slip rear differential helps ensure the engine’s power is distributed effectively during
cornering.
The high-performance drivetrain is expected to enable the Regal GS to accelerate from
0 to 60 mph in less than 6 seconds. That performance is complemented by a four-wheel-
independent suspension, with a unique High Performance Strut (HiPerStrut) design in
front. The HiPerStrut system helps reduce torque steer and maintain negative camber
during cornering. This improves ultimate grip levels in dry and wet conditions, as well as
improves the direct feel of the road, while isolating undesirable feedback. Behind the
wheel the driver experiences reduced torque steer, improved grip and increased
cornering power, along with crisper handling, steering precision and feedback.
The Regal GS features a high-performance Brembo brake system with 14 x 1.2-inch
(355 x 32 mm) cross-drilled rotors; four-piston, high-strength aluminum calipers, and
high-performance pads.
The Regal GS is also equipped with Interactive Drive Control System (IDCS) chassis
technology (also offered on Regal CXL models with the 2.0L turbo engine). It delivers
