840-HP Mercedes-AMG SL Looks Ready To Destroy Porsche

TheMercedes-AMG SLwas revealed last year as a luxury 2+2 roadster with loads of power. The SL 55 version's 4.0-liter twin-turbo V8 generates 469 horsepower with 516 lb-ft of torque, while the SL 63 version ups the ante to the tune of 577 hp and 590 lb-ft from the same motor. That may be far too much power for most, so a hybrid four-pot is coming too, or at leastso says the rumor mill. But what if you want even more power? Well, that's what the SL E Performance is for, and its hybrid powertrain is sure to blow occupants' hair back so far that even teenage passengers will develop receding hairlines. We spotted anearly naked prototype of this new model几乎两个月前,现在我们有fresh imagery.

As the red paint indicates (the last sighting was of a car finished in black), Mercedes is becoming a little more blase about spy photographers capturing SL development mules without camouflage. That's partly because this hybrid model has almost no changes from the one revealed in October last year, apart from a charging port in the rear bumper. If that placement seems familiar to you, it's likely because you remember thereveal of the blistering AMG GT 63 S E Performance. Sure, you probably didn't remember its full name, but you likely haven't forgotten that this four-door coupe is a true powerhouse.

Just like the SL, a 4.0-liter twin-turbo V8 is put to work, only here it makes 639 hp on its own. Combined with an electric motor that can produce an additional 204 horses and 236 lb-ft for ten-second bursts, maximum output sits at a staggering 843 hp and 1,034 lb-ft. Is that what the lighter, sportier SL E Performance will produce too? Not necessarily...
