The high performance, high-output GT R and GT R Pro receive much of AMG’s attention, especially in the performance department. The twin-turbo 4.0-liter V8 under the hood is shared with other GT variants, but thanks to a few new tricks, including a set of upgraded turbos, now produces 577 hp, up from the standard 469 hp. For 2020, the GT-R gets a newly designed set of headlights, a restyled diffuser, and a new set of AMG performance wheels. On the inside, expect to find a set of premium Nappa leather seats with microfiber inserts, as well as dual-zone automatic climate control and an optional HomeLink universal garage door opener. The new 10.25-inch high-resolution infotainment display includes integrated navigation, a four-speaker sound system, and Android Auto and Apple CarPlay integration. Active driver assistance features include adaptive high beam assist, forward braking assist, and driver attention assist. GT R Pro cars get a series of pure performance focused parts such as a built-in roll cage, updated coil-over suspension, and additional carbon fiber bits and pieces on the exterior, however power remains the same. It is, however, limited to just 150 units on US shores.
