Detroit 2011: 2012 BMW 1 Series M Coupe revs its beating heart

BMW's latest introduction to the U.S. market bowed today at the 2011 Detroit Auto Show, and it's a machine that's meant to light the true enthusiast's heart aflutter: the 2012 1 Series M Coupe. We must say, it looks rather striking in the metallic orange hue you see in our live photo gallery below.

Even more importantly, the 340 horsepower put out by its 3.0-liter turbocharged inline-six engine is said to "capture the soul of the original M3." Or so they say... BMW claims this new sportster was inspired by the 1988 M3, and the German automaker's intention is reportedly to "illustrate its ability to build race car performance into a small car, capable of everyday use."

Expect to see the new 1 Series M Coupe hit dealership lots in the spring of 2011 for $47,010, in limited quantities according to BMW.

Detroit 2011: 2012 BMW 650i Convertible goes topless in the Motor City

In addition to the scorched orange 1 Series M Coupe at the BMW booth in Detroit was the new 2012 BMW 650i Convertible. Under the sharply creased (and rather long) hood lies a 400-horsepower, twin-turbocharged, direct injected V8 that manages to shove out 450 pound-feet of torque between 1,750 and 4,500 rpm. All that grunt will be sent to the rear wheels through either a six-speed manual or eight-speed automatic transmission.

BMW claims the new 6 Series Convertible can drop its flying-buttress-equipped fabric top in exactly 19 seconds an there's also a 10.2-inch screen to control the standard iDrive technology package. Not bad, but such niceties are to be expected when you are asked to pay a wallet-busting $91,375 for the privilege of owning one, which you'll be able to do sometime in the spring of 2011.

Detroit 2011: 2012 Buick Verano is quietly powerful

If you were wondering how General Motors was planning to differentiate the 2012 Buick Verano from its Chevy Cruze counterpart, wonder no more. According to Buick, its newest addition will offer the quietest ride in its segment thanks to heaps of laminated glass, triple door seals and a host of other muting technologies. Buick calls the cabin "library quiet," though there's no word as to whether the interior smells of old books. They've also made sure to throw in the same levels of refinement as found in the likes of the Lacrosse, and drivers can expect to find the same high-quality leather and a host of tech goodies as the bigger four-door.

That's all fine and good, but we're more excited about what Buick has thrown under the hood of the 2012 Verano. Buyers who opt for the base car will be met with a 2.4-liter four-cylinder engine capable of 177 horsepower and 170 pound-feet of torque. Mated to either a six-speed manual or a six-speed automatic transmission, Buick is shooting for around 31 mpg highway. The really juicy news is that the Verano will also be available with the same turbo 2.0-liter four cylinder found in the Regal Turbo, and again with your choice of six-speed manual or automatic! That means this significantly smaller, lighter four-door will be available with a full 220 horsepower.

Detroit 2011: Audi A6 Hybrid is Teutonic efficiency

While we have already met the 2012 Audi A6, we weren't clear on what the A6 Hybrid would look like. As it turns out, we had a pretty solid idea, as Audi officials say they have gone out of their way to keep it aesthetically true to the conventional gas-powered model.

The new A6 hybrid is a front-wheel drive affair that offers Audi's 2.0-liter TFSI four-cylinder with a 45-horsepower/155 pound-feet of torque electric motor sitting ahead of the eight-speed Tiptronic gearbox. A modest 1.3 kilowatt-hour lithium-ion battery pack is resident in the trunk to generate 39 kW. Audi quotes an estimated combined fuel economy rating of 38 miles per gallon, noting that the A6 Hybrid can be coaxed up to 62 mph strictly on electricity, and it has a pure-electric range of three kilometers (1.86 miles).

Audi isn't confirming when this new model will go on sale, but it is widely understood that the gas-electric model was conceived with the U.S. in mind, so we wouldn't be surprised to see it roll into American dealerships before it hits the rest of the globe.

Detroit 2011: 2012 Audi A6 is predictably handsome

Audi has unveiled its mid-range 2012 A6 sedan, and as we learned from advanced photos, it follows closely in the mold of its big brother, the A8. As the range-topping sedan is a pretty piece, that's not a bad thing, but Audi seems to be channeling BMW's old "One sausage, three sizes" design mantra of decades ago. In this case, that means a massive single-frame grille, available LED headlamps (as shown), and a relatively simple and unadorned profile that lends the A6 a premium look that will likely wear well over the years.

The new A6 will be available globally with two gas engines and three TDI diesel powerplants, as well as a front-wheel drive-only hybrid model. The most powerful gasoline-fed model will be the 3.0-liter TFSI Quattro, packing 300 horsepower and 325 pound-feet of torque, routed through a seven-speed S tronic automatic.
