BMW officially reveals the new 2014 M6 Gran Coupe ahead of its launch next summer. Neatly filling a void between the M6 Coupe and M5, the M6 Gran Coupe is BMW’s response to Audi’s S7 and Mercedes-Benz’s CLS63. Here is a four-door gran turismo packed with all the power and luxury needed — featuring a twin-turbocharged 4.4-liter V-8 engine rated at 560 horsepower and 500 pound-feet of torque. Power is first sent to a seven-speed dual-clutch transmission and onto a unique limited-slip Active M Differential before reaching the rear wheels. Watch the video after the jump. [See & Read More]

Bentley‘s flagship vehicle the Mulsanne is easy to dismiss as yet another uber-luxury land yacht. Comfortable for sure but racy? Surely not, except that the Mulsanne packs a thumping 6.75-liter twin turbo V8 under that expansive hood. Developing 505 hp, that engine has got the guts to propel the three-ton monster from 0 to 60 mph in 5.3 seconds before going on to a top speed just shy of 200 mph. World Land Speed record holder Andy Green recently had the chance to take the Mulsanne for a little spin on the Bonneville Salt Flats and in the process hit almost 200 mph, all while riding in supreme comfort. Enjoy.

Speed obsessed sedan lovers have another new option. Although not substantially revised from the prior model, the new Maserati Quattroporte ($TBA) does offer a sleeker roofline, frameless doors, three side windows, and a more stylish interior, with a large touchscreen display in the dash and rear entertainment monitors for backseat riders. And, if the images are any indication, a 530hp V8 engine, which would be a healthy bump over the current 425.

BMW pulled the covers off its second generation Alpina B7 high-performance luxury sedan with a bit more power and a couple new design cues. The second generation Alpina B7 will start at $128,495 and will debut at the Pebble Beach Concours d’Elegance in August before it officially goes up for sale. The Germans gave the 2013 model a 40-horsepower bump to 540 and it can use its eight-speed trans to get up to 194 mph. Of course, the blue Alpina paint and 21-inch 20-spoke rims will continue to give the car it's distinct look. [See More]
