A super sports car with a green fig leaf in front of the grille? That has been in this league yet. Gigantic the riots two years ago was as a snazzy electric Tesla Roadster Fun shocked the automotive world. The electric Tesla is now long in the market. Other projects are yuo and even Daimler AG climbed in the California low-volume producers to prevent further flow faster.
But by 2015, wants the sporty Mercedes subsidiary AMG with its headquarters based in Southern Affalterbach even open a electric drum. If the Mercedes SLS AMG mid-September its world premiere at the IAA in Frankfurt, thousands of visitors will flatten in the new German Gullwing nose. 6.3 liters, the V8 powered, 571 hp, Alukarosse, double clutch and almost 320 km / h top are the figures of a man's toy, as it has long been no more.
"By 2015, we will launch the SLS with an electric motor on the market," says AMG boss Volker Mornhinweg to the weight of his testimony, "it was our goal to bring an e-drive in a supercar. Of course we can do a SLS eDrive not exceeding 300 km / h fast. But we benefit from the all-wheel drive, the lower center of gravity and the fact that we can drive all four wheels individually. "
Hybrid and Elektroanbtrieb not taboo for AMG
Mercedes and AMG have missed in the last few years so many Motor Trend. This is now in sight. AMG will show as the spearhead of the Daimler group that are not mutually exclusive sporty performance and reasonable consumption.
Technical innovations such as cylinder deactivation, direct injection and turbocharging to make only the beginning and reduce fleet consumption in the house AMG to 2012 by 30 percent. "Also, hybrid and electric drives are not taboo for us. But all our vehicles will remain typical AMG. Uncompromisingly sporty and PS-strong, "Mornhinweg looks to the future.
Four engines deliver 532 hp silent
A Gullwing with electric drive and excellent performance so far offered no. "Initially, our Packaging excellent opportunities to accommodate the electric drive in the car," said Mornhinweg, "just think of the great square, offer the V8 engine, exhaust system and transmission tunnel."
These components with a total weight of over 400 kg are at the first test aircraft already expanded end of the year and electric modules are replaced. Four electric motors mounted near the wheels make an impressive 392 kW/532 hp and a massive torque of 880 Nm, which is already at the start. The engine sound: silence.
Powered the four electric motors, a 51-pound three lithium-ion batteries. From each 140 kilograms of batteries is in the front, a fitted under the rear shelf and one in the transmission tunnel. The electric motors and batteries are manufactured by suppliers Brusa. The batteries have a nominal capacity of 40 Ah and an energy content of 48 kWh. From the outside, alone indicates the deaf twin exhaust points to the lack of Nitro. Else does the e-drive version, like any ordinary SLS.
Dynamics no worse than in a gasoline
With all the electronics should not be inferior to the driving dynamics of the gasoline engine, with its V8 engine and 571 hp. The weight distribution will be at 48:52 in favor of the rear axle. The chassis remains of slight modifications largely identical.
But the double wishbone front to be replaced by modified suspension system. "Especially, the dynamic driving capabilities of the drive captivate us tremendously," says Project Wolf Zimmermann, "with Torque Vectoring and switching similar recuperation during braking previous expectations are placed on an electrically driven vehicle on the head."
With electricity in 4 seconds from a standstill to 100 km / h
The bottom line outweigh the electrical components around 600 kilograms. Is, the Mercedes SLS AMG E-Drive brings in the experimental stage nearly two tons unladen weight on the scale. "The top speed of over 200 Km / hour," says Volker Mornhinweg, "at the range, we currently expect 150 to 180 kilometers." The sprint from 0 to 100 km / h should he put back thanks to four-wheel drive in about four seconds.
To the lithium-ion batteries to charge 80 percent, you have to the SLS E-Drive up to six hours to the outlet. For the complete charge requires about eight hours. If the gasoline-powered gullwing on a double clutch with seven steps, then get on the power of the SLS E-Drive with only one gear and the fixed ratio of 1:5.5.
