AMG-built. Soft top. Four seats.

It returns the SL to a fabric soft top (21 kg lighter than the previous folding hardtop), restores 2+2 seating as standard for the first time since the R129 era, and brings 4MATIC+ all-wheel drive and rear-axle steering to the range.
The lineup spans the mild-hybrid four-cylinder SL 43, twin-turbo V8 SL 55 and SL 63, the plug-in hybrid SL 63 S E Performance, and from 2025 the Mercedes-Maybach SL 680 Monogram Series — all paired with AMG SPEEDSHIFT MCT 9G.

Published Baumuster rows for the AMG SL range — from the mild-hybrid SL 43 to the plug-in SL 63 S E Performance — each with Motorkennung and AMG SPEEDSHIFT MCT 9G.
