With its carbon-fiber front fenders and trim, we expect the GT R Roadster to weigh about 3750 pounds. That's about 50 pounds less than the one-rung-down GT C roadster.

The roadster's folding softtop is shared with other GT convertibles and has three layers of fabric stretched over an aluminum, magnesium, and steel frame.

GT R models get a lighter exhaust system with three tail pipes, the largest of which is hexagonal. It's hard to miss.

You would expect the GT R's long, low front end to scrape on every driveway, speed bump and parking block, but it doesn't.

Compared to lesser GT models, the GT R's rear track and bodywork have been widened by 2.2 inches.

The GT R's twin-turbo 4.0-liter V-8 produce 577 horsepower at 6250 rpm, which is 108 more horsepower than in the standard GT models and 17 more than the GT C versions.

Huge carbon-ceramic brake rotors are standard, as are 19-inch front and 20-inch rear wheels wrapped with sticky Michelin Pilot Sport Cup 2 summer performance tires.

For the 2020 model year, all AMG GT models get a new 10.3-inch touchscreen, redesigned center console, standard Android Auto and Apple CarPlay integration, and a 12.3-inch digital gauge cluster.
