PHEV power makes SL most powerful yet
Big Merc roadster gets host of AMG upgrades
The big Mercedes roadster is more powerful than it ever has been before. The 2025 Mercedes-AMG SL 63 S E Performance keeps its V8 and now makes 805 hp and more than 1,000 lb-ft of torque thanks to its F1-inspired hybrid system.
Mercedes-AMG starts with its 4.0L twin-turbo V8. The engine makes 603 hp and 627 lb-ft, output levels we’ve seen before from the car.
Then AMG fits its E Performance drive unit on the rear axle. A permanently excited electric motor with a two-speed transmission that runs through a limited-slip differential. It adds 94 hp continuous and a peak of 201 horses. The 6.1 kWh battery gives the car a short electric-only range, but when you ask for full power it delivers. The battery can be charged by the engine, or by plugging into the wall.
Other AMG-specific treatments include Active Ride Control with active roll stabilization, rear axle steering, and AMG ceramic brakes. The performance upgrades are designed to make the AMG SL a high-performance machine and not just a luxury grand tourer.
The cabin has AMG upgrades as well, including AMG-specific gauges on the display and AMG Performance seats (with three massage programs). Mercedes-AMG will also offer a large number of choices for upholstery including leather and microfiber in an array of colours.
Mercedes-AMG says that the 2025 SL 63 S E Performance will go on sale late next year.
