The technology behind the Mercedes Benz SLS AMG E Cell
Electric car concept still is not really close to many people. However, no one dares to deny the efforts of automobile manufacturers in the innovation and development of electric vehicles. One of them, not to mention Mercedes-Benz SLS form E-Cell electric vehicle.
Torque 649 lb-ft and 525 hp output parameters are proud of the Mercedes-Benz SLS AMG E-Cell. Electric supercar has yellow highlights appear in several motor shows from last year to this.
E-Cell is not a half-hearted attempt to put electric drive system in the standard SLS. Instead, this is the result of intensive engineering projects derived from the F1 world.
Electric motor torque vectoring
"Heart" of the SLS AMG E-Cell is four synchronous electric motor, mounted in the chassis near each wheel. Transmit power to all four wheels as traction and support vector torque from the wheel operated individually. This helps cornering characteristics can be adjusted almost infinitely and reduce reliance on electronic balancing system which is useful for the enthusiastic driver.
Low weight
Low weight helps vehicles achieve high standards of performance brand AMG. Carbon fiber reinforced plastic (CFRP) has been widely used, like aluminum. Benefits of bring CFRP include weight reduction of about 30% compared with aluminum, but the higher power.
Pin mounted inside the carbon fiber bodywork immediately increase safety but also allows central weight distribution and low maintenance. According to Mercedes-Benz, you can expect the highest standards of safety from E-Cell.
Even Mercedes-Benz also uses a different measure of attractiveness. Each carbon fiber thickness is only 1/10 of a human hair and weighing only 25 g.
F1 technology
Many automobile manufacturers claim, they enjoy the cars technology from the racetrack. However, in many cases, such a relationship is very fragile. Fortunately, this is true in the case of the SLS AMG E-Cell.
Carbon ceramic brake rotors are the first contact from the racing world, with large capacity and resistance to corrosion, even when used at high intensity. This technology also helps reduce vehicle weight 40% compared with rotors conventional gray cast iron. From there, create favorable conditions for the handling unladen weight and increased sensitivity of the steering mechanism.
The dampers pusher style race car replaces the system arranged vertically on a regular SLS. The reason is that electric drive system requires setting the other car.
Kinetic energy recovery system (KERS) is integrated in the car. Kinetic energy transformed into thermal and electrical energy when braking, then be used to provide additional power for the fixed position during rotation.
The same technology is integrated in hybrid models over the years, but Mercedes-Benz has used 48 kWh battery dedicated to equipping F1 E-Cell. Lithium-ion high-voltage, liquid-cooled. Like the F1 KERS system, braking energy recovery.
The most important thing for people who are all interested in this technology is not being wasted. Mercedes-Benz is expected to launch SLS AMG E-Cell to market in 2013, with small-scale production.

David E Davis Jr 1930 2011
David E. Davis, Jr., the founder of modern automotive journalism, is dead. He was 80.
Regular readers of TireKicker know how much I admired David. One of my lifes regrets will be that we never met. Theres a lot to say about David and I think its said best by Car and Drivers Eddie Alterman. Please click here.
UPDATE:
A few hours later, and there are more things about David E. I think are worth reading. Autoweeks Steven Cole Smith does a good warts-and-all look at Davis, including a reference to a video you can watch here on TireKicker, where David told of the dream he had involving once-protege Jean Jennings and a piano falling from a passing jet.
Theres Jean Jennings herself, who wrote what at the time wasnt an obit for the just-out 25th anniversary issue of Automobile about her career with and after DED, Jr...and her side of the shift in power at that magazine that led to Davids piano dream.
And theres Peter DeLorenzo in a two-days early update of Autoextremist, who paints the bigger picture and makes it starkly clear that, despite the talents of Eddie Alterman and many others, with the passing of David E., the days of the American car magazine as we know it are numbered and the digits are few.
Finally, lets remember the man through his own work and words. His defining moment...the 1968 review of the BMW 2002, which changed automotive journalism from analytics to advocacy and in which David threw down the gauntlet, demanding to know why America couldnt build a sedan like this (he was only a decade ahead of the hipsters and two ahead of the rest of the car-buying public).
And, from 15 years later, the marvelous lunacy that happened on his watch (complete with sidebar by DED, Jr. himself)...as most of his writing staff take 8 loaned press vehicles south of the border for sun, fun, dysentery, public urination, bribery, floods and one dead cow. It took 26 years for Top Gear and its Defense Department-sized budget to finally topple this as my favorite piece of automotive journalism.
It was one hell of a ride. Thanks, David. Rest well.
