About the 2018 Mercedes-Benz AMG SLC

3rd generation (R172), second US model year after the SLC facelift and rename; minor equipment-update year

The Mercedes-AMG SLC is a compact two-seat roadster that combines strong sports-car performance with Mercedes comfort and a power-retractable hardtop. Its defining difference from many soft-top rivals is the ability to function like a small closed coupe with the roof raised, while AMG tuning adds a powerful V6, sharper responses, stronger brakes, and a more engaging exhaust. It suits drivers seeking open-air performance without giving up everyday luxury features.

The SLC 43 AMG is a compact two-seat performance roadster with a 362-hp twin-turbo V6, a nine-speed automatic, AMG-tuned suspension, stronger brakes, and an active sport exhaust. Its power-retractable panoramic hardtop gives it coupe-like weather protection, while heated memory seats and neck-level heating make open-top driving more comfortable in cool weather.
