Buick has spent the last decade shredding its perception as the low-level luxury vehicle for geriatrics, but the brand hasn’t always been associated with that crowd.

The Buick Regal GS is powered by a new 3.6-liter V6 with 310hp and 282lb-ft of torque, with the engine also featuring direct injection and cylinder deactivation.

The sole transmission is a 9-speed automatic, and drive is to all four wheels via General Motors’ twin-clutch all-wheel-drive system. As expected, the Regal GS debuts with a 310 horsepower V6 that sends its power to all four wheels.

Now, finally, Buick has revealed its new Regal GS and divulged all the juicy details. The lack of a manual gearbox is perhaps disappointing, but it’s also unsurprising, given that Buick dropped the manual from the previous-gen Regal GS a few years ago.

The GS is basically a sport-tuned version of the all-new Buick Regal. Selectable modes allow the driver to tailor the auto to fit the situation. The front end has been reworked with new vents and a different grille, while a subtle decklid spoiler and dual exhaust tips round out the changes in the rear. The GS gets special front seats unique from the rest of the GS line, with heating, cooling, massaging and adjustable seat and seat-back bolsters and thigh support.

There is also a flat-bottom steering wheel, sports pedals and sill plates to let you know that this is the fastest of the range.

Some available goodies worth adding are LED headlights and a head-up display.

Base price is $39,990 including destination, which is almost $5,000 more than the outgoing model.

On the safety side, the optional Driver Confidence II package includes front pedestrian braking, lane keep assist with lane departure warning, forward collision alert, and adaptive cruise control with forward automatic braking. At $39,990 with destination, it undercuts both the $45,750 Acura TLX A-Spec SH-AWD and $47,245 Lexus IS350 F-Sport by a significant margin. Answer is that we’re cheating a bit, and posting this from an embargoed press release just as Buick unveils the Regal GS to us.
