Mercedes-Benz is using the 2017 Detroit auto show to introduce the AMG GT C Edition 50, a special-edition AMG GT sports car that commemorates the 50th anniversary of AMG. In addition, the automaker is also revealing the refreshed 2018 AMG GT and GT S, both of which feature more power and additional go-fast goodies. A coupe variant of the AMG GT C also joins the lineup as part of the refresh.
The 2018 Mercedes-AMG GT C Edition 50comes with a special paint called designo Graphite Grey Magno, black chrome highlights on the side skirt trim, front splitter, air inlets in the grille, side air outlet fins on the front fenders, rear diffuser, and tailpipe trim. Black chrome-accented cross-spoke AMG forged wheels also come standard, as does an "Edition 50" badge on the rear. Inside, the contrasting black and silver theme continues with silver pearl/black Nappa leather, gray diamond pattern topstitching, "GT Edition 50" embossing on the headrests, and a black Dinamica microfiber performance steering wheel with gray contrast topstitching, "Edition" lettering on the bezel, and a silver pearl 12 o'clock mark. Additional standard features include the AMG Interior Night package, which adds steering wheel spokes, paddle shifters, and door sill panels in black, along with carbon fiber matte interior trim with black piano lacquer accents. In total, only 100 examples of the AMG GT C Edition 50 will be produced, split into 50 coupes and 50 roadsters.
As for the other variants of the 2018 Mercedes-AMG GT, the whole lineup receives a refresh that includes a revised grille known as the AMG Panamericana grille. The AMG GT R's AirPanel active air management system is now standard on all AMG GT variants. The system features vertical louvers than open and close for improved cooling or to improve aerodynamics and reduce drag. Mercedes-AMG has also added more power to the AMG GT and AMG GT S. Output of the 4.0-liter twin-turbo V-8 jumps to 469 hp and 465 lb-ft of torque in the AMG GT, a 13-hp and 22-lb-ft increase, and to 515 hp and 494 lb-ft in the AMG GT S, a 12-hp and 15-lb-ft bump.

AMG Ride Control sport suspension is standard on the AMG GT C coupe and roadster, and it comes with an electronically controlled adaptive adjustable damping system. A rear-axle limited-slip differential comes standard on all but the base AMG GT.

It adds an AMG performance steering wheel in Dinamica microfiber, black paddle shifters and steering wheel spokes, black stainless steel door sills, a black cross-strut, and black backrests for the seats. An AMG Exterior Carbon Fiber package is also now available on all AMG GT models and adds a carbon fiber front splitter, front fender side fins, side mirror covers, a rear diffuser, and side skirt inserts if you have a GT C. There's also a new AMG Track Pace feature that lets you use a smartphone app to analyze and improve your technique on the track and share your lap times with other AMG drivers on social media.
