The main change between the GT3 and GT4 versions of the vehicle lies under the bonnet - the full-monty GT3 machine shares its naturally aspirated 6.2-litre V8 with the discontinued SLS supercar, while the GT4 uses the same 4.0-litre twin-turbo V8 as the road-going GT coupe as well as the latest Mercedes-AMG C63 sedan. The latest one being in the form of the AMG GT4. Today, the AMG GT4 makes its debut before this weekend's Spa 24 Hour race, with customer deliveries set to start later this year. After the achievements in GT3 racing, the Mercedes-AMG GT4 is opening another valuable platform for us to prove our competence as a globally successful sports vehicle and performance brand. The GT4 is a track-only race machine that covered 18,641 miles during its rigorous testing on the race track.

Meet the new Mercedes-AMG GT4, the race-ready version of Mercedes' flagship AMG GT R coupe and a cousin to the GT3 machine already doing the rounds in the Bathurst 12 Hour and Australian GT Championship.

Just because Mercedes-AMG is getting out of German Touring Cars in favour of Formula E, doesn't meant the Affalterbach whitecoats are giving up on big, hairy-chested V8 racing cars anytime soon.

You can find out more details on the new Mercedes AMG GT4 at the link below. It is powered by the same 4.0-liter biturbo V8 engine found on the GT R. However though the AMG GT4 only produces 510 PS and over 600 Nm of torque instead of the GT R's output of 585 PS. In the GT4, this engine offers up to 503 hp and over 443 lb-ft of torque and is mated to the same six-speed sequential gearbox as its GT3 sibling. In the end, the GT4 only weighs around 1,390 kilograms while the R is 240 kilograms heavier.

The lightweight aluminium spaceframe of the road-going GT R has been reinforced with a bolted-in high-strength steel roll-cage; in addition to street-standard carbon-fibre parts such as the front wings and torque tube, the bonnet, front apron and front splitter have been replaced with race-spec carbon-fibre components, keeping the weight of the vehicle down to about 1390kg. To give a resemblance of comfort, customers can opt to have an air conditioning system installed on their GT4, but will increase the weight. With the vehicle having an air conditioning system, it isn't far fetched that someone would drive it on the streets.
