2025 Mercedes-Benz SL-Class Convertible Trims Comparison

The entry-level AMG SL 43 starts with a turbocharged four-cylinder engine (416 horsepower, 354 lb-ft of torque), while upgrading to the AMG SL 55 brings a turbocharged 4.0-liter V8 (469 hp, 516 lb-ft). The AMG SL 63 massages that same V8 for more power (577 hp, 590 lb-ft). The AMG SL 63 S E Performance takes the V8 to another level, pairing a hand-built engine (603 hp, 627 lb-ft) with an electric motor on the rear axle. Total combined output is a remarkable 805 hp and 1,047 lb-ft of torque.
