2025 Mercedes-Benz AMG SL: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2025 Mercedes-Benz AMG SL is the new SL 63 S E Performance, an 805-hp plug-in hybrid that combines a twin-turbo V8 with a rear electric motor. The SL 43 also gets more power, but the range has no broader redesign or refresh.
About the 2025 Mercedes-Benz AMG SL
7th generation (R232), fourth model year; no redesign or mid-cycle refresh.
The AMG SL is a four-seat, soft-top grand touring car that blends open-air luxury with sports-car performance. Mercedes-AMG emphasizes its racing heritage, powerful engines, adjustable driving character, and year-round usability. Compared with more narrowly focused sports cars, the SL places greater weight on comfort through massaging seats, neck-level heating, a quiet power roof, modern cabin technology, and usable—though small—rear seats.
The 2025 range starts with the lighter, rear-wheel-drive SL 43, moves to the V8-powered and all-wheel-drive SL 55, and tops out with the 805-hp SL 63 S E Performance plug-in hybrid. All three are luxury roadsters with a power-folding soft top, while standout equipment ranges from massaging seats and an adjustable 11.9-inch touchscreen to the hybrid model's active suspension, front-axle lift, rear-wheel steering, and carbon-ceramic brakes.
