2018 Mercedes-Benz AMG GT: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for 2018 is a major lineup expansion, with open-top and more performance-focused versions joining the AMG GT family. It is a substantial mid-generation update rather than a full redesign.
About the 2018 Mercedes-Benz AMG GT
1st generation (C190 coupe/R190 roadster), third US model year; major range expansion and front-end styling update
Mercedes-AMG presents the GT as a purpose-built two-seat sports car that combines racing-derived engineering with comfort for road use. Its defining layout places the V8 behind the front axle and the transmission at the rear for balanced handling. Compared with softer luxury roadsters, the AMG GT emphasizes direct steering, strong braking, a low seating position, and dramatic V8 performance, while retaining heated power seats, navigation, climate control, and usable luggage space.
The 2018 range stretches from the road-focused 469-hp GT Coupe and Roadster to the wider 550-hp GT C and track-focused 577-hp GT R. The GT C adds rear-wheel steering and adaptive suspension, while the GT R brings adjustable suspension, nine-level traction control and active aerodynamic hardware.
