Buick Regal Grand Sport
The 2010 Detroit Auto Show showcased the 2011 Buick Regal GS. When I first saw the Buick Regal and the Opel Insignia I was blown away and it was a car I could not wait to make production here in the states. Recently there have been spy shots of the Regal GS testing in North America but still there has been no official word from GM to be entered into production. Car bloggers have been saying it is only a matter of time before they announce the GS being part of the Buick Lineup.
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 enhanced vehicle stability and greater driving safety, while also adapting the driving characteristics of the car to the driver’s preferences. The driver selects among three operating modes – normal, sport and GS – that change the suspension settings, throttle response and steering sensitivity through the variable-effort steering system.

It looks like a chrysler, GM is really taking note from Japanese cars as far as quality goes; it’s good to see.
I just bought a 2010 Malibu with the 2.4/6 speed A/T.My test drive didn’t include ant hills. I habitually downshift on hills to avoid overuse and heating of the brakes. It wasn’t until I purchased the car that I realized there is no way to downshift the 6 speed. My manual cleverly suggests that I downshift on grades but it doesn’t say how. The manual gives little attention to the manual gear which is my best hope for downshifting. Have you given any thought to this problem? Gordon.
