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.

Mercedes-AMG GT R coming with active aero, shocks, steering

We've seen the Mercedes-AMG GT, and we've seen the Mercedes-AMG GT S. So what comes next? According to Motor Trend, the Mercedes-AMG GT R, that's what. Word has it that the forthcoming addition AMG's flagship sports car range will wear a similar name to Godzilla. Of course, Nissan might have a thing or two to say about that, but considering that, as it is, the letters GTS are also used on by BMW and Porsche (to say nothing of the Dodge Viper), Daimler might still find itself in the clear. Naming schemes aside, the upcoming top-of-the-line AMG GT is naturally expected to pack more power than existing versions. But it's also tipped to get a four-wheel steering system to improve cornering and high-speed stability, similar to those featured on the Porsche 911 GT3 and Ferrari F12 TdF. A new type of adjustable spool-valve shocks are also said to be in the works, along with active aerodynamic elements. Expect upgraded rolling stock, brakes, and interior to come as part of the package when it debuts in about a year from now. MT also reports that AMG is also already working on a new E63 based on the forthcoming W213-generation E-Class. The new super-sedan is expected to shed weight by replacing the old 5.5-liter twin-turbo V8 with the newer, more compact 4.0. It's also tipped to get a new nine-speed dual-clutch transmission and a more flexible all-wheel-drive system to replace the fixed 33/67 front-rear torque split on the current model.

Mercedes to roll out C63 AMG late in 2014 with 4.0L V8

The new 2014 Mercedes-Benz C-Class is upon us, launching initially in North America with turbocharged four-cylinder C300 4Matic and six-cylinder C400 4Matic flavors. But that's only the tip of the proverbial iceberg when it comes to the vast array of powertrain configurations that will be offered in the new C-Class in markets around the world. Orders will soon be rolling in for gasoline, hybrid and diesel engines with four, six or eight cylinders, driving the rear wheels or all four, with the seven-speed automatic transmission soon to be replaced by a new nine-speed unit. But what enthusiasts are really looking forward to is the next C63 AMG.
As BMW has done with the M3 (and new M4), Mercedes has gradually ratcheted up the cylinder count in its AMG C-Class, graduating from the 3.6-liter V6 in the original C36 AMG to the 4.3-liter V8 in the C43 AMG, then the 5.5-liter V8 in the C55 AMG before going the distance with the sublime 6.2-liter V8 in the C63 AMG. Like its rivals, Mercedes is expected to use turbochargers as a replacement for displacement in the next model, but unlike its Bavarian rival, it won't be losing any cylinders in the process.
Skipping the 5.5-liter twin-turbo V8 that has gone on to power other AMG models, the next C63 AMG is still expected to introduce a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower. It'll also reportedly keep the same seven-speed automatic transmission (instead of switching to the new nine-speed), but the jury's still out on whether it'll come with rear- or all-wheel drive (or offer buyers the choice). The downsized V8 - codenamed M177 - is then expected to find its way into other models, but the C-Class will be the first to get it when it arrives before the end of the new year ahead.
