Inside the Mercedes-Benz SLS AMG E-Cell

Mercedes-Benz SLS AMG E-CELL

Can an electric of one of the world’s supercars be a supercar? has answered this question a resounding yes by announcing the SLS AMG E-Cell was confirmed for production in Detroit in will be available in 2013. Its powertrain gives the E-Cell a km/h (63 mph) time of 4.0 compared to the SLS AMG’s 0-100 time of 3.8 seconds. When it to top speed, both cars are limited. The E-Cell can hit 250 km/h mph), while the SLS AMG tops out at 317 (197 mph). While not the equal of the gas-powered SLS AMG, the is clearly in supercar territory!

The all-wheel drivetrain is a product of a two long joint development of Mercedes-AMG and Mercedes AMG High Powertrains in Brixworth, England. A one per wheel electric design, the synchronous electric motors rev up to rpm (a governor prevents operation at speeds) and provide a peak of 525 horsepower and a peak torque of 650

The E-Cell has a direct drive which would be a guaranteed for stalling with a gas-fueled However, in the E-Cell, the peak 650 of torque is available up to about rpm, so the vehicle is very at low speeds.

For comparison, the SLS AMG has an M159 that, like all gas engines, has little torque at low rpm, and builds up to its peak torque at rpm. Similarly, while the engine has a larger peak (571 hp at 6,850 rpm), the delivers more horsepower at all speeds below 5,000 and is still providing about 400 at 12,000 rpm.

Each individual wheel is driven and electrically braked, and wheel’s characteristics can be tuned to the conditions. This additional of control helps to optimize in corners, reduce oversteer/understeer, traction, reduce the steering and angle, and minimize the intrusion of the stability program on the driver’s

The E-Cell is some 400 kg (840 heavier than the gas-powered SLS AMG all those batteries do come at a The 48 kilowatt-hour (kWh) battery a range of about 145 km (90 miles). AMG is to provide 60 kWh batteries in the commercial extending the range to about 210 km miles).

Of course, the actual will depend on your style. AMG’s estimate is to be conservative by Jens Meiners of Car and . During his review, the E-Cell was to its limits on a variety of surfaces and yet achieved an indicated range of 85 miles (136.8 km).

Cooling systems insure the electric motors, the battery, and the control electronics are maintained at a operating temperature. The battery can be for operation in winter, and can receive cooling from the air conditioner in driving.

The E-Cell provides driving programs, comfort, sport plus, and manual. In the mode, only 40 percent of the power is available, and handling is damped to avoid unpleasant In sport mode 60 percent of power is available, and the damping on the is considerably reduced. Although the is limited in these modes, the throttle will provide power for those moments you want to pass with In sport plus, there are no Manual mode acts sports-plus, but also turns off the braking.

Speaking of regenerative braking, the electric motors work as to slow the car while recharging the the flexible style of the E-Cell shows here. There are levels of regenerative braking, not the manual driving program turns it off entirely. The levels are by paddles on the steering column. one and two are quite mild, so that the feels like a regular car to a stop. Level three is aggressive, while in level the regenerative braking is so strong it feels like the regular are on. All modes help extend the range by returning some of the energy to the battery.

Conventional of the E-Cell is provided by high-performance composite brakes direct the F1 circuit, which boast short stopping distances, performance, and outstanding fade The oversized discs (front 402 x 39 mm, rear discs: 360 x 32 mm) are made of strengthened ceramic, and are 40 percent than conventional brake reducing unsprung weight and steering response.

The body shell is made of fiber-reinforced polymers (CFRP), and an integral spine within the E-Cell’s battery is located. components are 50 percent lighter steel, and 30 percent lighter aluminum, providing weight which help to overcome the weight of the lithium-ion polymer

The design of the battery compartment is to be a zero intrusion cell, the integrity of the battery cells in the of a crash.

The front axle had to be from that of the SLS AMG, to the introduction of all-wheel drive. The SLS wishbone design is replaced an independent multi-link suspension pushrod struts, similar to used in F1 racing. This allows the heavier E-Cell to the same levels of agility and dynamics as are exhibited by the SLS AMG, combined with electrohydraulic and pinion steering.

Now for the bad news — the SLS AMG E-Cell is to cost upwards of US$250,000, and the run will be sold by invitation Common folks will access to the E-Cell in the 2014 year. Still, for an electric that can outrun the Tesla perhaps the price and wait be bearable.
