Mercedes-AMG GT R Pro arriving in September

The Mercedes-AMG range is about to receive its wildest model yet, something the firm is calling its “ultimate track day racer”.

Australia is set to receive 15 examples of the low-volume Mercedes-AMG GT R Pro, of which just 750 units will be produced in total.

Priced at $453,200 before on-road costs, the GT R Pro boasts a Nürburgring lap time of just 7:04 minutes, more than six seconds quicker than the regular GT R.

It accomplished that not through any engine upgrades but through a raft of changes aimed at making it lighter and stiffer than any other GT.

The GT R Pro is a veritable orgy of carbon fibre. There’s an adjustable torsion bar up front that’s made of the stuff (the rear bar is steel), while there’s a carbon-fibre shear panel under the rear end to add stiffness.

All GT R Pros feature a carbon package, with a carbon fibre front splitter, rear wing, side mirrors and roof and carbon fibre finish on the diffuser and elsewhere on the exterior.

It also features a Track Package, with a bolted steel roll cage, two rear braces, and four-point safety harnesses for the front seat occupants.

A new AMG coil-over suspension system has greater adjustability, with the driver able to adjust the compression and rebound of the dampers without having to pick up a tool – it’s done via a click system and an adjustment dial on the damper.

Other modifications include retuned dynamic engine and transmission mounts and ceramic high-performance compound brakes.

The hero colour combination seen here is matte Selenite Grey finished with light green wrap stripes. All other colourways feature matte dark grey stripes, while every GT R Pro use lightweight 20-inch forged wheels finished in titanium grey.

Finally, the interior features clear-coated carbon fibre bucket seats upholstered in Nappa Leather and Dinamica suede, seatbelts finished in silver, and carbon fibre trim on the centre console and door trims.

The twin-turbocharged 4.0-litre V8 engine under the GT R Pro’s long bonnet produces the same 430kW of power and 700Nm of torque as the regular GT R, sending power to the rear wheels via a seven-speed dual-clutch automatic transmission. The 0-100km/h time of 3.6 seconds is also identical.
