Why it stands out

The 2017 Mercedes-Benz SL-Class stands out as a luxury roadster that blends performance, technology, and everyday usability in a way few convertibles do. For this model year, the SL400 used a 3.0-liter 329-horsepower V6, while the SL550 kept its twin-turbo 4.6-liter V8 and gained power to 449 horsepower. The AMG versions added even more drama, with the SL63 offering 577 horsepower and the SL65 bringing a 6.0-liter V12 with 621 horsepower. That range of engines gives the 2017 SL-Class a broad appeal, from strong all-around grand touring to serious straight-line speed.

The 2017 refresh also brought a meaningful technology update. Mercedes added updated exterior styling, LED headlights, automatic emergency braking, keyless entry, ambient interior lighting, Apple CarPlay, and Android Auto. The car also used a nine-speed automatic transmission with paddle shifters, and its cabin featured Mercedes’ MBUX infotainment system with an 11.9-inch screen. Buyers also got adaptive suspension systems, rain-sensing wipers, driver attention monitors, crash-responsive head restraints, lane keep assist, adaptive cruise control, and night vision depending on specification. The electrically folding fabric roof remained standard, and the SL’s rear seats made it a four-seater, though the space back there is limited.

That combination of luxury and hardware makes the 2017 SL-Class appealing, but it is not without compromises. The trunk is modest at 7.2 cubic feet with the top down and three more cubes with the top up, so cargo space is not a strong point. It is also a complex car, and some owners note that certain systems can be tricky to use. Even so, the 2017 Mercedes-Benz SL-Class remains distinctive for delivering high-end comfort, serious power, and a long list of advanced features in a single, stylish convertible package.
