And by "money" we mean 169,000 euros (plus VAT).
It was almost a year ago when BMW Motorsport announced its intentions towards doing a GT4-spec M4 Coupe race car and now the factory-built machine is being revealed in full after completing more than 20,000 kilometers (12,427 miles) of tests. Slotting between the M235i Racing and the flagship M6 GT3, the new M4 GT4 is a mélange between the regular road-going M4 Coupe and the beefier sold-out GTS version — all wrapped up in a lighter package.
The inline-six 3.0-liter turbocharged engine with more than 431 horsepower and the seven-speed dual-clutch automatic transmission have both been borrowed from the road-going car and adapted for the new track-only application. The engine’s output is not set in stone as there are multiple configurations to choose from thanks to power sticks allowing the team to pre-program the desired level of power. It’s actually the first race car from BMW Motorsport to boast power sticks and these are of the plug & play type, so the team can quickly make changes should the situation require it.
Borrowed straight from the aforementioned GTS is the carbon fiber hood while the doors are made from the same lightweight material. The beefier body optimized in the wind tunnel for hours also includes a massive wing to aid downforce at the rear axle while at the front there’s a motorsport-spec front splitter also engineered to enhance aero. The soundtrack provided by the six-cylinder engine comes out through the racing exhaust system.
The diet also consists of a stripped-out interior with just one seat sourced from the M6 GT3 from where the new M4 GT4 has also inherited the brakes and pedal box. BMW says the philosophy behind the cabin is to make it as comfortable as possible as a way to allow the person behind the wheel focus on what’s important: driving.
The M4 GT4 has already been evaluated by numerous BMW works drivers and it will once again be put through its paces this weekend at the Nürburgring 24 Hours in the BMW Sports Trophy to obtain more knowledge about the race car. It will share the track with another M4 GT4, a media car driven by British motorsport journalist Jethro Bovingdon.
Scheduled to arrive in the hands of customer racing teams for the 2018 season, the BMW M4 GT4 carries a starting price of 169,000 euros (plus VAT).

Sales launch for the newly-developed BMW M4 GT4
Customers can now order the new BMW M4 GT4, the latest model in the BMW Motorsport product range. The technologically advanced car has completed over 20,000 kilometres of tests, multiple hours in the wind tunnel, extensive application runs for fine-tuning purposes, and successful test outings under race conditions.
BMW Motorsport Director Jens Marquardt, together with Dirk Adorf (GER), who was heavily involved in the testing of the car as development driver, launched the sales phase during an exclusive customer event at the Nürburgring (GER). The BMW M4 GT4, which is ready for use thanks to a comprehensive starter package, will cost 169,000 Euros (plus VAT).
“Even after many years, the launch of a new car is still one of the absolute highlights for me as BMW Motorsport Director,” said BMW Motorsport Director Jens Marquardt at the presentation event in the paddock at the Nürburgring. “The start of the sales phase sees us reach another milestone with the BMW M4 GT4. We are looking forward to seeing the car enjoy success in the hands of our customer teams from 2018. We are offering our customers a sophisticated and reliable GT4 car, which incorporates all of BMW Motorsport’s expertise, coupled with the strong basis provided by the BMW M4 Coupé. The development of the BMW M4 GT4 focussed on mileage, cost efficiency and ease of maintenance.”
Production technology meets motorsport innovation.
This is guaranteed by the use of proven production technology and innovative developments from the BMW M6 GT3. The engine and transmission, including control electronics, were adopted from the BMW M4 Coupé (combined consumption: 8.3 l/100 km; combined CO2 emissions: 194 g/km). The carbon bonnet comes from the BMW M4 GTS (combined consumption: 8.5 l/100 km; combined CO2 emissions: 199 g/km). In addition, the BMW M4 GT4 has carbon-fibre doors, motorsport-specific front splitters and rear wings, and a racing exhaust system. The seat, brakes and pedal box make use of solutions that are also included in the top model in customer racing, the BMW M6 GT3. The interior concept is designed entirely for the comfort of the driver, so that he or she can focus fully on driving.
The BMW engineers went in a totally new direction in terms of engine control software. The BMW M4 GT4 is the first BMW Motorsport car to be fitted with power sticks, which can be pre-programmed for different engine performance levels. Thanks to the system, which has been approved by the SRO Motorsports Group and is well protected against manipulation, Plug-and-Play gives BMW Motorsport customers the ability to react quickly and flexibly to changes to the Balance of Performance in various races.
Next big test: 24h Nürburgring.
In recent months, the BMW M4 GT4 has been tested by many BMW works drivers, Juniors and customer racing drivers at various racetracks, with different tyre types and in a wide range of external conditions. The purpose of this testing was to adapt all the technical applications, such as the DSC stability system and ABS, to meet the demands of motor racing in as much detail as possible. The car has already proven its reliability and performance in races on the Nordschleife and at the 24 Hours of Dubai (UAE).
The outing at this weekend’s Nürburgring 24 Hours is the next tough test in the development of the BMW M4 GT4. Dirk Adorf (GER), BMW Motorsport Junior Ricky Collard (GBR) and Jörg Weidinger (GER), test and development engineer at BMW M GmbH and himself a very successful participant in the BMW Sports Trophy for many years, will use the endurance classic to gain more valuable knowledge about the new car. They will race at the Nürburgring 24 Hours alongside British motorsport journalist Jethro Bovingdon (GBR) in the BMW M4 GT4 media car, with the support of tyre partner Hankook. Never before has a journalist had the opportunity to drive a pre-production BMW car like the BMW M4 GT4.
