BMW has shown a teaser for the new M4 GT4 for amateur racing. The current F82 generation coupe has been competing since 2018, with 33 wins and nearly 100 podiums in its debut season. The upcoming sports car will consolidate and multiply the success of its predecessor, and, along with the XM hybrid crossover, will be part of the celebration of the 50th anniversary of the BMW M division.

GT4 car races are held by the SRO Motorsports Group under the auspices of the FIA, and today there are 18 such championships in the world. Since this is an amateur competition, the cars here are not as powerful as in the GT3 or GT, and are as close to the road as possible. The current BMW M4 GT4 was unveiled in 2017, with an entry threshold of € 169,000. At the beginning of 2021, the coupe was upgraded to the Evo version. According to BMW M Motorsport, they have listened to customer feedback and made the car “more competitive and more profitable to service.”

When building the BMW M4 GT4, the standard M4 (F82) was taken as a basis. The inline-six 3.0 on the coupe develops 470 forces, although the exact figure depends on the balance of performance. The control electronics are borrowed from the serial machine. The transmission consists of a seven-band “robot” with racing software and a main gear with a mechanical differential and a separate cooling system. A safety cage is welded into the chassis of the two-door. The roof, doors and hood are made of CFRP (Carbon Fiber Reinforced Plastic) and the glass is replaced with Makrolon polycarbonate.

For the sake of weight reduction, lightweight electrical wiring is also used. The suspension has been redesigned with new levers, Ohlins dampers, adjustable springs and anti-roll bars. The stock brakes are replaced by AP Racing mechanisms with two-channel air cooling, six-piston fixed calipers at the front and four-piston at the rear. The diameter of the discs is 390 and 355 millimeters, respectively.

The new M4 GT4 is likely to follow the G82 coupe in many ways. The road car is equipped with a three-liter “biturbo-six” S58 with a return of 480 or 510 horsepower and in the all-wheel drive version of the M4 Competitiоn Coupe M xDrive shoots up to “hundreds” in 3.5 seconds. The rear-wheel-drive Competitiоn two-doors do the same exercise in 3.9 seconds. Regular M4s cost 4.2.
