SPIED: Mercedes-Benz' SLS AMG Roadster Loses the Top and Gullwing Doors

Mercedes-Benz is nearing the end of the development process of its forthcoming open-top SLS AMG Roadster, which will join the coupe model when it enters the market late next year. Apart from dropping the metal top in favor of an electrically operated fabric roof, as you can see from the location of the door handles in these latest spy pictures, the SLS AMG's famous Gullwing-style doors have made way for more conventional items.

The Roadster model will also gain a pair of partially hidden roll bars located behind the front passengers, which will deploy higher in the event of a rollover crash. The firm's Airscarf neck-heating system will most likely be offered on the standard list.

Under the elongated hood, the SLS AMG Roadster won't differ mechanically from its tin-top twin featuring the same 6.3-litre V8 powerplant with 571HP and 650Nm (479 lb-ft) of torque. A seven-speed dual-clutch transmission will handle the delivery to the rear wheels. However, buyers should expect some minor losses in performance because of the added weight of the body-strengthening measures, which compensate for the removal of the rooftop.

Mercedes Confirms Production Version of SLS AMG E-Cell All-Electric Supercar at Detroit Motor Show

Mercedes-Benz showcased its SLS AMG E-Cell concept car at the Detroit Motor Show, however, the big news wasn't the presentation of the all-electric supercar but the announcement that it will enter production within the next couple of years.

"The Mercedes-Benz SLS AMG E-CELL is the most technically advanced super sports car in the 125-year history of the automobile, and shows just how fascinating electromobility can be," said Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars, at the press conference. "Our customers will be able to order it from their Mercedes-Benz dealers from 2013 onwards."

At the heart of the all-electric supercar are four, high-revving, synchronous electric motors, which can reach 12,000 rpm, producing a combined output of 526 hp (392 kW) with a peak torque of 880 Nm (649 lb-ft) of torque, enough to catapult the E-Cell to 100 km/h (62 mph) in just 4 seconds or almost as fast as the stock SLS’ 571 hp V8 gasoline engine (3,8 seconds).

The E-Cell’s drive is also comprised of a liquid-cooled lithium-ion battery featuring a modular design and a maximum electric load potential of 480 kW. Aside the power outlet, the 400-volt battery can also be charged by the regenerative braking system.

It might be a green machine, but the E-Cell is also a thoroughbred sports car. By positioning the electric motors as close to the wheels as possible and carefully placing the battery modules throughout the chassis, engineers managed to obtain a near-perfect weight distribution. The new front suspension, boasting a multilink setup with pushrod damper struts, is another feature usually found on high performance cars, alongside the oversized ceramic composite brakes.

Finished in a fluorescent “AMG lumilectric magno” paint, the body has been fitted with an extensive aerodynamic kit. The 10-spoke 19-inch AMG alloys, shod in 265/35 front and 295/30 rear tires, round up the exterior appointments.

Inside, there’s a new instrument cluster and center console housing a 10-inch display, used to operate all audio, climate and navigation functions. Other touches include the black/white nappa leather combination, sport seats and steering wheel.

Mercedes-Benz SLS AMG GT3 Takes Third Place in its First 24H Race

Mercedes-Benz completed the development and testing phase of its SLS AMG GT3 racecar last week by taking part in the Abu Dhabi 24-hour endurance race (January 13 to 15). All three participating teams managed to finish the race, with the number 7 Black Falcon vehicle driven by Thomas Jager, Jan Seyffarth, Kenneth Heyer, and Sean Paul Breslin claiming third place.

"It was a good team performance overall which was rewarded with a third place that we can be proud of," said Thomas Jäger. "Achieving a good finish for all three cars at the first attempt was an important affirmation for all those involved.".

The SLS AMG GT3 competing for Heico Motorsport with starting number 9, took seventh place overall, coming in 18 laps behind the winner, while Black Falcon's second gull-wing model finished 69 laps behind the winner to claim 24th place.

It's worth noting that all three SLS AMG GT3s in the 24H Dubai race sported the Ducati logo, which refers to the partnership agreed in November 2010 between Mercedes-AMG GmbH and Ducati Motor.

According to Mercredes-Benz, following homologation and specification of the balance of performance by the FIA worldwide governing body, delivery of the SLS AMG GT3 will commence at the end of February 2011 with the sales price set at be € 334,000 Euro (net) /€ 397,460 (incl. 19 % VAT).

Mercedes-Benz SLS AMG Gullwing Photo: Genuine or Fake?

Could this scanned photo from the latest issue of German car magazine, Autobild, be providing us with our fist look at the Mercedes-Benz SLS AMG Gullwing? Hard to say, but we reckon that even if the photo has been digitally tampered (aka Photoshoped), what you see here shouldn't be too far off from the production car that's slated to hit showrooms in the spring of 2010.

The SLR McLaren's replacement that is being developed in-house by Mercedes-Benz's AMG division, will be powered by a front mounted 6.3-liter V8 engine producing 571 HP.

According to a previous release from the Stuttgart-based automaker, the SLS AMG should hit the 100km/h (62mph) mark from standstill in 3.8 seconds and reach a top speed of 315 km/h or 196 mph.
