Mercedes-Benz AMG’s SL roadster has spawned a range-topping option packing a V-8-based plug-in hybrid powertrain good for 805 hp.
The new SL 63 S E Performance made its debut late on Monday and is due in showrooms next year. It will arrive in the U.S. as a 2024 model.
The car’s powertrain is a familiar one, as versions of it already feature in the AMG GT 63 S E Performance 4-Door Coupe and AMG S 63 E Performance. The setup is also destined for the redesigned AMG GT Coupe, the SL’s coupe counterpart.
The powertrain combines Mercedes’ twin-turbocharged 4.0-liter V-8 with an electric motor at the rear axle for a peak output of 805 hp and a monstrous 1,047 lb-ft of torque. A 9-speed automatic for the V-8, a 2-speed automatic for the electric motor, and a conventional all-wheel-drive system with a limited-slip differential complete the drivetrain package. By giving the engine and electric motor their own transmissions, more torque can be delivered to the wheels, according to AMG.

Powering the electric motor is a 6.1-kwh battery. An estimate for electric range hasn’t been given, though AMG said the battery is designed more for delivering high power as opposed to long range. The battery uses technology derived from Formula 1, which allows it to charge and discharge high power in rapid succession while remaining relatively low in weight.
Key to this is a sophisticated liquid cooling system that keeps the battery’s operating temperature within an ideal temperature range, thus ensuring there isn’t any reduction in electric power due to a battery that’s too warm or too cold.
Performance claims include a sprint to 60 mph from rest in 2.8 seconds and a governed top speed of 196 mph. The numbers are impressive given the likely weight of the car. The V-8-only SL 63 already weighs 4,343 pounds. Add the electric motor, battery, and other hybrid hardware and the weight will probably reach close to 4,800 pounds or more.
Pricing information will be announced closer to next year’s market launch.
