Mercedes-Benz GLA Concept crossover leaked ahead of Shanghai debut

With just a few days left before the start of the Shanghai Motor Show, images of the Mercedes-Benz GLA Concept compact crossover have emerged online. The little 'ute is based on the small A-Class hatchback, and though it shares an identical wheelbase, is larger in every other dimension.
Looking like a rough-and-tumble five-door hatchback on the tippy toes of its 20-inch wheels, the GLA is most certainly destined for production in a toned down form that will borrow many bits and pieces from other cars based on this platform like the aforementioned A-Class and the CLA-Class sedan. Carscoop reports that the production version of the GLA will be revealed at the Frankfurt Motor Show in September of this year, with sales to the public starting in 2014.
Since it's based on the A-Class, we expect that the production GLA-Class will be powered by your choice of Mercedes' 2.0-liter turbocharged inline four-cylinder engine and a diesel or two, and will offer transmissions that include the company's seven-speed DCT and perhaps a six-speed manual (at least in Europe). If the GLA follows the same path as the two cars before it, expect a GLA45 AMG producing over 300 horsepower, as well. As for what powers the GLA Concept, that just might remain a mystery until the vehicle is officially revealed in China.

Xcar spools up the Mercedes-AMG GT

Xcar has sampled its fair share of high-performance machinery. And a fair few of them have come from Stuttgart and its satellite in Affalterbach. The British video crew had yet to sample the new Mercedes flagship, but it takes care of that in this latest installment. That's right, it's time to check out the new Mercedes-AMG GT. AMG's new twin-turbocharged halo car has a tough act to follow, hitting the scene in the wake of the celebrated Mercedes SLS AMG, what with its gullwing doors and big atmospheric V8. But even with those big, wide rubber shoes to fill, Xcar finds there's plenty to love in the new AMG GT – particularly in the exhaust note, which is far from a given from a forced-induction engine. And with as much as 503 horsepower on tap, Xcar aptly points out that it's as potent as many a supercar from just a few years ago. Yet it's far more reasonably priced – in relative terms, that is. It's enough to not only put BMW's M and Audi's Quattro divisions to shame, but put Porsche on notice in the process. And therein lies the vital question: is it better than a 911? Even a 911 Turbo? That's the answer that Xcar seeks to find in this latest video, but you'll want to watch it for yourself to see what conclusion they've reached. Related Video:

Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.
