Mercedes-Benz AMG SL

2022

The Mercedes-Benz SL (R232) is the seventh generation of the Mercedes-Benz SL-Class roadster, succeeding the R231 model. Introduced on 28 October 2021, the R232 serves as a direct replacement for the GT Roadster. It was exclusively marketed under the Mercedes-AMG brand until the introduction of the Mercedes-Maybach SL in August 2024.

Design

Roof system

The R232 has several departures from its previous SL-Class predecessors, one of which is the design of the convertible roof. AMG switched from a folding metal roof to a fabric-lined roof that utilizes electric motors compared to hydraulics which reduces the weight of the car by 21 kg (46 lb). This was done to lower the center of gravity for improved handling. The R232 is also fitted with the fourth generation of Mercedes all-wheel-drive system, 4Matic, and rear-axle steering.

Seating and dashboard

The R232 reintroduced 2+2 seating as standard for the SL, a feature which hadn't been present on an SL model since the C107 and R129, which had the optional 2+2 seating. The dashboard is symmetrical, with a 12.3-inch digital instrument cluster and an 11.9-inch touchscreen panel in the center. The instrument cluster is placed within a binnacle which Mercedes claims to reduce the reflections from the sunlight and improve visibility when the roof is folded down. The touchscreen panel in the center is electronically tiltable to the vertical position for the same reason.

Frame

The car's platform is an aluminum space frame self-supporting body structure developed by AMG to provide more rigidity. Transverse rigidity and longitudinal rigidity are said to be 50% and 40% higher, respectively compared to the GT roadster platform. AMG's chief technical officer, Jochen Hermann, reported that the SL shell weighs 270 kg (595 lb).

Technical data

At the launch, the sole engine option was a biturbo 4.0-litre V8 with two different levels of output: SL 55 4MATIC+ and SL 63 4MATIC+. The lesser SL 55 is rated at 350 kW (476 PS; 469 bhp) and 700 N⋅m (516 lb⋅ft) while the SL 63 has 430 kW (585 PS; 577 bhp) and 800 N⋅m (590 lb⋅ft). The base six-cylinder inline engine and a more powerful hybrid version of the V8 engine are to be introduced at later date. The 4-cylinder model is added with the SL 43. The SL 43 is rated at 280 kW (381 PS; 375 bhp) and 480 N⋅m (354 lb⋅ft) which adds an extra 10 kW (14 PS; 13 bhp) for mild hybrid. This marks the first time the SL-Class has been powered by an inline-4 engine since Mercedes-Benz 190 SL.
