Move over Toyota, Mercedes have a bigger Battery Drill.

"The world's most powerful series production electric car." That's   how Mercedes-Benz is describing its fancy new SLS Electric Drive.   Blimey. So how on earth has it managed that? Cleverness. And being a bit   German...
Underneath the familial bodywork, the ‘leccy SLS has a special   driveline of four synchronous electric motors driving each individual   wheel, giving it permanent four-wheel drive. The four motors, which   weigh 45kg apiece, whisk up a total of 740bhp and 738lb ft of torque.   That's 177bhp and 259lb ft (TWO HUNDRED AND FIFTY NINE!) more than the   6.2-litre fossil burner.

To put the power down MB's given the ED two separate gearboxes that   power each axle directly. Alongside it, there's a fancy AMG Torque   Dynamics system that selects which wheels need the most drive depending   on traction. Along with the monstrous motors, this means it'll squirm   from 0-62mph in 3.9 seconds (0.1 seconds slower than the V8).

Funding the motors is a liquid-cooled 60kWh lithium-ion battery pack   (MB's British arm, High Performance Engines helped develop it with AMG,   as it goes). It weighs 548kg and it's stuffed in the transmission tunnel   down the centre of the cabin, and behind the seats where you'd   ordinarily find the fuel tank

You'll have to wait 20 hours per charge, mind. That said, there is an   optional wall box, which provides a 22kW quick charge function, filling   the stores in three hours. The battery also gets a top-up when you're   braking and coasting, and in the SLS you can choose how much is   recuperated.

So, those batteries. Heavy, aren't they? To make up for the mass,   MB's made the car out of aluminium and carbonfibre and fitted a set of   402mm/360mm carbon ceramic brakes. We haven't got any word on whether   the car's lighter or heavier than standard, though.

The front suspension's also been redesigned to account for the newly   driven wheels - there's a pushrod system with horizontally mounted   dampers and springs. The old steering's also been binned and replaced by   a speed-sensitive electro-hydraulic system.

How much does it cost, then? €416,500 (£330,972) when it goes on sale   next year. That's £162,547 more than standard...But what of the noise?   That glorious funny-firing-order V8 jackhammer? Well, there's a "Power"   button that activates a sound designed for "each driving situation"   that's played through 11 speakers tucked around the cabin.
Power source.
