2019 Mercedes-Benz SL: What's New, Specs & Features
Last updated August 4, 2026
The 2019 Mercedes-Benz SL is a carryover model with no major changes. The SL 450 and SL 550 retain the same engines, retractable hardtop design, safety equipment, and cabin technology as in 2018.
About the 2019 Mercedes-Benz SL
6th generation SL (R231, 2013-2020), after the 2017 refresh and near the end of the generation.
Mercedes positions the SL as a traditional luxury roadster more than a stripped-down sports car. Its core appeal is open-air driving with year-round usability thanks to the retractable hardtop, plus strong biturbo power, a polished cabin, and comfort-focused technology. Against sharper rivals, the SL’s identity is effortless speed, long-distance comfort, and classic Mercedes grand-roadster character rather than track-first aggression.
The SL 450 is the entry model, but it is still a well-equipped luxury roadster with a 362-hp twin-turbo V6, adaptive suspension, heated leather seats, navigation, Apple CarPlay, and Android Auto. The SL 550 adds a 449-hp twin-turbo V8, ventilated massaging seats, neck-level heating, hands-free trunk access, and parking assistance. Both use a nine-speed automatic transmission and a power-retractable hardtop with a panoramic roof panel.

2019 Mercedes-Benz SL
(63 reviews)
“This vehicle is the complete luxury sports car that delivers all of necessary features and is fun to drive. The automated hardtop is great. Too bad it is being discontinued after 2021.”
“Name: 'The Avatar' because of the seats: they breath in and out as you make turns or go over bumps. Love the ride...handles perfect, takes the bumps better than most sports cars. Takes turns like a race car-tight. Good visibility all the time-top up or top down. Best comfort of all cars. (I have the special seats). Interior is beautiful. Exterior is beautiful-excellent paint job. Love my car.”
