That’s right! The G 63 Edition 55 is not the only one marking Mercedes-AMG’s 55th anniversary this year. It’s also the GT Track Series—which is a more hardcore version of the GT Black Series. The track-day car is limited to 55 units and is priced at €369,000 (ex Affalterbach, VAT excluded) in Germany.
On the exterior, just like the GT Black Series, the GT Track Series also wears a generous amount of carbon fibre aero elements, but it’s the decals and pinstripes that add to the drama. The track car rides on 18-inch forged wheels, shod with slicks measuring 325/660 at the front and 325/705 at the rear. The wheels hide brake discs measuring 390 mm at the front and 355 mm at the rear.
The suspension setup comprises aluminium double wishbones front and rear, with shock absorbers adjustable for rebound and compression.
Inside, the GT Track Series gets bare essentials for track use, including 12-step motorsport ABS and traction control adjustability. Safety systems include a high-tensile steel roll cage, a five-point safety harness, a motorsport-grade fire extinguisher, and an extrication hatch in the roof.
The 4.0-litre V8 biturbo engine has been borrowed from the GT Black Series. Here it offers 540 kW (734 metric hp) and 850 Nm (627 lb-ft) of torque, paired with a 6-speed sequential gearbox with a mechanical (adjustable) self-locking differential.
Since a lot of “road content” has been deleted from the GT Black Series, the kerb weight here is 1,400 kg (3,086 lbs) as opposed to 1,640 kg (3,616 lbs) of the road car.
