New All-Electric Mercedes Supercar Has 740 hp...




The skunkworks team in Affalterbach knows how to make AMG-branded Benzes the most-intimidating-sounding cars on the planetóin particular, the sounds of its 5.5-liter twin-turbo V-8 and naturally aspirated 6.2-liter V-8 are exalted hymns in the church of car enthusiasm. (Listen to us run nine AMGs through a tunnel in Detroit.) But with the introduction of the 2014 SLS AMG Electric Drive, Mercedes-Benz AMG has introduced its first truly stealth supercar. (We have to ask: Hasnít parent company Daimler learned its lesson with the Electric Drive moniker? We digress.)

Not only is the electric supercar AMGís quietest model by a long way, but itís also the brandís most powerful. Electrification provides the SLS with 740 hp and 738 lb-ft of torque, with all the twist available from a standstill. The electricity is generated by four contact permanent-magnet synchronous electric motors that spin to 13,000 rpm and through a so-called axially arranged transmission. In comparison, the new-for-2013 petroleum-powered SLS AMG GT churns out 583 hp and 489 lb-ft. Benz claims the electrified SLS will hit 62 mph in 3.9 seconds before topping out at an electronically limited 155.

Power is routed through what Mercedes is calling AMG Torque Dynamics; this provides the car with selective all-wheel drive and allows each wheel to be independently powered or braked to assist in handling maneuvers. The system can be switched among comfort, sport, and sport plus modes. The motors arenít located in the hubs, saving unsprung weight, but each corner does feature carbon-ceramic brake discs measuring 15.8 inches in front and 14.2 inches in the rear. Power is stored in a liquid-cooled 60-kWh, 1208-pound lithium-ion battery pack developed by Mercedes-AMG and Mercedes AMG High Performance Powertrains of Brixworth in the U.K.óthese are the people responsible for Mercedesí kinetic energy recovery system (KERS) in Formula 1. The battery pack consists of 12 modules, each made up of 72 lithium-ion cellsóthatís 864 cells in total, if youíre keeping score at homeóthat, like all hybrids, receive a charge under deceleration. When static, the SLS Electric Drive can be charged in three hours via an optional 22-kW quick-charge station; plugging it straight into an unmodified wall outlet, a full charge takes 20 hours. Once the electric SLS is full of juice, Mercedes claims a maximum range of 155 miles, although honking on the thing no doubt rapidly decreases that number.

1. No it ain't

 

The electricity is generated by four contact permanent-magnet synchronous electric motors


Electricity is not generated...

Other than that, tone down the gut wrenching acceleration and extent the mileage some and I want one.

2. How many hours would a minimum-wage America worker have to work to pay for this nifty

machine?
