Wondering what it takes to get your foot in the door of the GT4 racing feeder category? First and foremost you’ll need a car, and Mercedes-Benz has answered the call with a GT4-prepped version of its AMG GT.
At €198,850 (around A$292,500) the Mercedes-AMG GT4 doesn’t exactly provide race thrills on a budget, although the GT4 is a comparative bargain compared to the flagship Mercedes-AMG GT3 which asks for an extra $250,000.
At its core, the GT4 is based upon the most aggressive version of the road-going GT, the GT R, using that car’s 4.0-litre twin-turbo V8 that shares its design with other members of the Mercedes-AMG range including the C63 and E63, instead of the GT3’s naturally aspirated 6.2-litre V8.
Driveline changes include the installation of a paddle-shifted six-speed sequential transmission in place of the road car's dual clutch automatic transmission, with power fed to the rear wheels via an adjustable limited slip differential.
Mercedes points to peak outputs of 375kW and 600Nm from the the GT4’s engine, although that figure could be dialled back in race trim to balance its performance with less potent machines such as the BMW M4, Porsche Cayman and Ford Mustang.
An advanced traction control and anti-lock braking system should help drivers keep it on the track, and there is a carbon fibre driver safety cell and special emergency-access roof hatch if it all goes wrong.
Expect to see the Mercedes-AMG GT4 racing alongside its GT3 sibling in a GT4 sub-class at Bathurst and beyond from 2018.
