2018 Mercedes-AMG GT lineup adds power and tech to the sports coupe

You might not see any changes with your eyes, but rest assured, Mercedes-AMG included them in the 2018 GT lineup.

All variants of GT now sport the Panamericana grille, which features vertical slats.

The front bumper also earns larger intakes.

All GT variants also receive GT R's active front aero, which closes intake tracts to improve efficiency when the extra air isn't needed.

The base GT's engine now puts out 469 horsepower and 465 pound-feet of torque, increases of 13 and 22, respectively.

The midrange GT S now puts out 515 hp and 494 torques, increases of 12 and 15, respectively.

GT R holds steady at 577 hp and 516 pound-feet.

There's also a new trim for the coupes -- GT C, which rests between GT S and GT R.

There's no word yet on pricing. Models will launch starting in the summer, continuing on through the fall.
