2012 Buick Regal GS makes good use of its 270 hp – Click above to watch video after the jump

The 2012 Buick Regal GS is set to hit dealerships this fall, but that means engineers still have time to fine-tune the vehicle before it arrives in showrooms across the country. What better way to do that than to take the Regal GS to the automaker's Milford Proving Grounds? This Michigan road course is a twisting, turning stretch of asphalt that allows engineers to really put a vehicle through its paces.

The hi-po Regal GS is powered by a direct-injected 2.0-liter turbocharged Ecotec four-banger, which pumps out 270 horsepower and 295 pound-feet of torque. That's enough horses to coax the sedan from 0 to 60 in 6.7 seconds, according to General Motors estimates. A few more notes about those power figures: First, when the Regal GS was first announced, we were only promised 255 horses, so 270 is a very welcome figure.

Second, the Regal GS and its 2.0L turbo boasts more torque than the larger 3.6-liter Pentastar V6, which produces 260 pound-feet in the Chrysler 200, and the 2.0-liter Turbo in the Hyundai Sonata, which is rated at 269 pound-feet of twist (to be fair, the latter two have never claimed to be sport sedans). What else does it beat? The list includes the Acura TSX V6, Audi A4, Lexus IS250 and the Volvo S60 T5. Plus, 95 percent of that peak torque is available from 2,300 to 4,900 rpm.

It's also worth mentioning that, with 135 horsepower per liter, the new boosted Ecotec boasts the highest specific power output of any engine in GM's history. It's also the most power-dense rating the SAE has ever officially recognized. That's impressive stuff.

Now we bet you're ready to watch a Buick test driver push the 2012 Regal GS around the track. Stop reading and click past the jump for the clip. Also, be sure to take a look at the full press release for more information on this new, sporty Regal.

Buick Regal GS Cranks 270 HP and 295 Lb-Ft of Torque
Exclusive Ecotec 2.0L turbocharged engine delivers more launch force than imports

DETROIT – The 2012 Buick Regal GS, which arrives at dealerships this fall, has been SAE-certified to deliver 270 horsepower (201kW) and 295 lb.-ft. of torque (400Nm) for an estimated 0-60 mph performance of 6.7 seconds.

Regal GS's exclusive Ecotec 2.0L direct-injected turbocharged four-cylinder engine delivers more torque than Acura TSX V-6, Audi A4 Sport, Lexus IS 250 and Volvo S60 T5. Torque is the twisting force that gets a vehicle moving and what the driver feels when accelerating.

"The Regal GS 2.0L turbo delivers the highest specific output of any production engine GM has ever offered, and at 135 hp per liter is the most power dense engine ever certified by SAE," said Mike Anderson, Ecotec global chief engineer and program manager. "We've been combining direct injection and variable valve timing with boosted engines since 2006, and there's no question the Regal GS turbo has the responsiveness and acceleration of some V-6s, while delivering the fuel economy you'd expect of a four-cylinder."

Ecotec 2.0L turbo highlights include direct injection, continuously variable valve timing, forged steel crankshaft, twin scroll design turbocharger and an efficient intercooler system. The peak torque of 295 lb-ft is achieved at a relatively low 2400 rpm. There is 95 percent of peak torque available between 2300 and 4900 rpm.

The GS's engine is mated to a standard six-speed manual transmission, and gets an estimated fuel economy of 28 mpg on the highway. A six-speed automatic transmission will be available later. The entire GS powertrain is covered by a five-year, 100,000-mile warranty.

Further reinforcing Regal GS's performance appeal is its Interactive Drive Control System chassis technology, which delivers enhanced vehicle stability. The driver selects among three operating modes that change the suspension settings, and steering sensitivity through the variable-effort steering system. "GS" mode optimizes the car for dynamic driving, tightening the suspension and steering response. "Standard," or the default mode, is the setting for all-around use. "Sport" mode provides a level of performance between standard and GS modes.

Regal GS also features a four-wheel-independent suspension, with a unique High Performance Strut (HiPerStrut) front suspension design. The HiPerStrut system helps reduce torque steer and maintain negative camber during cornering to keep the all-important tire contact patch on the pavement. The driver experiences improved grip and increased cornering power, along with crisper handling, steering precision and feedback.

The four-link independent rear suspension is designed to minimize unwanted toe and camber effects during spirited driving maneuvers, enhancing vehicle stability and tire grip. Both front and rear dampers incorporate active Computer Damping Control, continuously changing damper characteristics in real time to maintain optimal vehicle ride comfort over varying road surfaces and profiles. More aggressive, performance-oriented damping characteristics can also be selected by the driver when choosing "Sport" or "GS" mode.

Braking power comes from a large diameter four-wheel disc brake system featuring big, four-piston Brembo front calipers for optimal feel and modulation. A standard, four-channel anti-lock brake system is tuned to reduce stopping distances over varied road surfaces and conditions. The Regal GS also features standard StabiliTrak electronic stability control with integrated, full-speed traction control.

The GS cuts a sportier stance, too, with a lower ride height than other Regal 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).

"The 2012 Regal GS is well balanced with dynamic ride and handling, powerful brakes, great acceleration and excellent fuel economy," said Robert Casparian, Regal product marketing manager. "And the fact that one can get such great performance in a gorgeous sport sedan makes it even more attractive."

      I don't understand why GM didn't produce the Sky Redline, Soltice GXP, HHR SS and Cobalt SS with their stage 1 kits from the factory. It is the same engine, but 290 BHP and 340 lbft of torque in a package that weighs even less... I own a Cobalt SS with this stage kit and it would walk all over this because of the torque and weight advantage. I mean, at 260 BHP from the factory, it was like 5.7 sec 0-60 and is even better now with the stage kit. Those vehicles (with a GM approved part) have a specific power output of 145 HP per liter...

      I like the looks. AWD would definitely be a plus (as would a more powerful engine) which might be available in future versions. My big concern is the price. The current Regal Turbo tops out at 35k. How much is this gonna cost because you have a lot of options at the 40k mark (like the G37 Sport--RWD--328hp)?

      Now thats a cool car, but it better be priced right or it will outright fail.

      GM said originally it would be 0-60 in less than 6 secs, Hopefully autoblog made a typo :)

      They should have FWD/AWD like the Kizashi. FWD for regular mode, choice of FWD/AWD for Sport and GS mode is AWD! You get good economy numbers for day to day driving and 4 wheeled for cutting up the back roads. Also, AWD for the winter.

      Thank god, I knew GM could've been that stupid to leave it at only 255hp. I wish it could be closer to 300hp, but 15hp is a good increase. I'm sure the aftermarket will take it past 300hp with a simple ECU flash.

      This car looks great but with no AWD it's a huge dissappointment. I don't care how good their marketing team makes it look going around a track:(

      That's amazing, the seemingly best all-around, sporty car from GM is... a Buick

      I saw 4 guys on their way out to pick up chicks in their brand new Buick Regal. I wish I could fidget my phone out of my pocket, nothing like watching a bunch of white haired guys that obviously have smoking problems as they looked like they were in their 80's. One was wearing a ball cap so they must be in Buick's target range they are claiming to be going after.

      With Obama not making any indications that he is interested in bring down the price of fuel. Perhaps GM should be trying to match the 33 and 34 mpg highway that the Sonata and Optima get. I care about performance as much as the next guy, but if it requires premium fuel (the Sonata and Optima get 274 hp on regular 87 octane), and gets 10% less fuel economy, you really aren't doing much better than just having forked over for a modern V6. As silly as the Accord is right now, they manage 30 mpg highway with their timing belt cald, non-DI, and SOHC ancient J-series V6. If this Buick gets its rated power on regular or doesn't take a huge performance hit on regular, all the while hitting mid 30's in fuel economy, I personally will buy one. However, I think that is asking too much and I don't think this thing will get much over the 30 mpg that the 2.0L ecotec gets in other applications.

        Obama has made it possible to drill for oil companies to dig at more sites off the coast of the US, what the blasted hell are you talking about? Oil speculation is what has been driving up the price, much the same way it will more than likely rise again since summer is coming.
