AMG’s latest release promises 661 horsepower and a top speed of nearly 200 mph.
Mercedes has finally divulged the official details on the SL65 AMG Black Series, and it’s even more impressive than our spy reports indicated.
AMG engineers took the SL65 AMG—already a ridiculously fast car—and began removing weight. First they removed the heavy mechanism for the folding hardtop and replaced it with a fixed roof that cuts a flatter line across the car. The front splitter, hood, trunklid, and rear spoiler are all made of carbon fiber to further trim weight. Overall, Mercedes says curb weight is down 550 pounds versus the SL65, to around 4000.
Power comes from the same twin-turbo 6.0-liter V-12 engine as the regular SL65, but with a heavy dose of adrenaline. That engine already produces 604 horsepower, but AMG saw fit to endow the Black Series with 661 horses at 5400 rpm. Torque output is unchanged at 738 pound-feet, although Mercedes says the engine is detuned from 885, likely to keep the heavy-duty five-speed automatic transmission alive. The Black Series’ transmission, however, adds a fourth transmission setting, M2 manual mode, which shifts a claimed 25 percent quicker than M1 mode. As before, there are also Comfort and Sport settings for the automatic modes.
