“THE VEHICLE IS BEAUTIFULLY DESIGNED AND EXECUTED. HOWEVER, THE PRICE TO SIZE OF THE VEHICLE IS VERY DISPROPORTIONATE. HAVING SAID THAT, I OBVIOUSLY STILL WANTED THE VEHICLE. THAT, I BELIEVE SPEAKS FOR ITSELF.”
2020 Mercedes-Benz SL: What's New, Specs & Features
Last updated August 4, 2026
The 2020 Mercedes-Benz SL is a light final-year update, not a redesign. The main equipment change is standard remote start on the SL 450, while a limited Grand Edition joins as a special end-of-run model.
About the 2020 Mercedes-Benz SL
6th generation SL (R231, 2013-2020), final U.S. model year before the SL skips 2021 and returns as the redesigned 2022 AMG SL.
Mercedes-Benz positions the SL as a luxury roadster first and a sharp sports car second. Its core appeal is open-air grand touring: strong turbo power, a folding hardtop that gives coupe-like comfort when closed, and a rich two-seat cabin designed for long drives as much as quick bursts of speed. Compared with more focused rivals, the SL stands out for everyday comfort, quiet cruising, and features that make top-down driving pleasant in a wider range of weather.
The SL 450 is the comfort-focused version, with a twin-turbo V6, power-folding hardtop, navigation, Apple CarPlay, Android Auto, and heated seats. The SL 550 adds a twin-turbo V8, ventilated massaging seats, a neck-level heater, and automated parking assist for a more richly equipped grand-touring experience.
