The Mercedes-AMG GT has only been around since 2016, so most would still consider it a new model. Nothing changes for 2017, either, but that’s just fine. The GT can be had in three forms: GT, GT S, and GT R. No, not Nissan’s GT-R; take note of the missing hyphen. Regardless of trim, the GT represents Mercedes-AMG’s hottest and most potent model. It’s certainly a worthy successor to the SLS AMG and its gullwing doors. I recently got behind the wheel of the 2017 GT S at the famed Circuit of the Americas Formula One track outside Austin, Texas during the Texas Auto Writers Association’s Springtime Auto Roundup. A quick lap around the 3.4-mile course is all it takes to solidify the GT S a something well beyond the average sport coupe.
