Since its market introduction for the 2018 season, the Mercedes-AMG GT3’s “little brother” has been a regular part of GT4 and club racing grids worldwide.
Now there’s an updated and upgraded version of the car. Those updates include an optional power increase from 375 kW/510 hp to 400 kW/544 hp, making the car the most powerful GT4 in its competitive environment. The optimised version of the Mercedes-AMG GT4 is specifically aimed at track day activities, where the Balance of Performance that is required for GT4 class competition is not a consideration. Mercedes-AMG is also offering an additional high-downforce front splitter as well as twelve-inch wide rear wheels to enhance the race track performance even further.
The GT4 version of the AMG GT has scored 115 overall wins, 353 class wins and 209 podium finishes from 768 races: since its market introduction in 2018 in series ranging from ADAC GT4 Germany, DTM Trophy, IMSA Michelin Pilot Challenge, GT4 European Series and the Nürburgring 24-hour race.
In addition to track days, the modified front splitter and the wider rear wheels can also be used in the so-called SP8T class of the Nürburgring Endurance Series. The class for GT4 cars with turbocharged engines with a capacity of up to four litres is also part of the ADAC 24h Nürburgring Qualifier and the ADAC TotalEnergies 24h Nürburgring race.
Visually, the GT4 remains largely unchanged and comes in the familiar AMG design. It is only underneath the standard coating in iridium silver metallic that a slight modification can be found. A front apron made of natural fibre reinforced material replaces its predecessor reinforced by carbon fibre. During the production of the new front bumper of natural fibre reinforced material, the CO2 emission is lower than to date. As a result, the production process is environmentally friendlier. As the material that has been used doesn’t splinter in case of possible damage, safety has been enhanced as well. Punctures as a result of parts that have come loose can be prevented in this way and the risk of injury for mechanics is being reduced.
As of now, the Mercedes-AMG GT4 with the new performance level can be acquired directly from Mercedes-AMG GmbH Affalterbach. The standard delivery comes with an output of 375 kW/510 hp that can be increased to 400 kW/544 hp at a net surcharge of 2,990 Euros. The net sales prices of the car in the basic version without air conditioning amounts to 215,000 Euros.
Stefan Wendl, head of Mercedes-AMG Customer Racing: “We have made the decision to unleash even more power for our GT4 cars to enable additional flexibility in terms of set-up for our customers on one hand and on the other hand to simply provide more fun at the race track. That, in the process, we also have the most powerful GT4 in the competitive environment at the same time, is filling everybody in Affalterbach with pride. Next to the performance increase, we were also able to make the production process more sustainable and to enhance the safety, all of which enabling us to provide our customers with a successful overall package.”
