Powering the new Coupe is the P58 3.0-liter inline-6-cylinder M TwinPower Turbo engine producing up to 590 hp.

The BMW M4 GT3 will retail for $530,000 in the US (excl. shipping). The Competition Package adds $55,000 and includes additional headlights, backlit door numbers, TPMS with 8 sensors, spring and brake pedal travel measurement systems, BOSCH CAS-M rear-view camera radar system, an additional set of rims, and one day of training on the BMW M Motorsport M4 GT3 simulator.

In North America, the BMW M4 GT3 will be eligible to compete in the GT Daytona and GT Daytona Pro classes of the IMSA WeatherTech SportsCar Championship, as well as the GT class of the SRO Fanatec GT World Challenge America powered by AWS and SRO GT America powered by AWS series.

“BMW of North America is preparing to welcome the BMW M4 GT3 for the 2022 racing season and support our BMW Customer Racing family behind the latest offering from BMW M Motorsport,” said Victor Leleu, BMW NA Motorsport Manager. “We have little doubt that this car will be as successful as its predecessor, the BMW M6 GT3 – most recently the IMSA GTD winner at Mid-Ohio with Bill Auberlen, Robby Foley and our friends at Turner Motorsport.”

The first international race outing for the new BMW M4 GT3 will be on June 26th, 2021 at round four of this season’s Nurburgring Endurance Series (NLS).

The P58 M TwinPower Turbo engine in the M4 GT3 is some 80 lbs. lighter than the 8-cylinder engine found in the BMW M6 GT3. This leads to better weight distribution. Based on the S58 found in the new M4 Competition Coupe, the M4 GT3’s engine receives additional modifications including a change in the engine’s mounting angle, a dry-sump, an engine-mounted oil tanks with integrated oil / water exchanger, intake system with charge cycle split and two throttle valves, an exhaust system with charge cycle split, GT3-spec engine mounts and rear torsional vibration dampers.

 “503 hp and 479 lb-ft – this is the most powerful straight-six engine we’ve ever fitted in a production car (M4 Competition),” said Marcus Engelke, Project Manager Drivetrain, BMW M4. “590 hp and 516 lb-ft – this is the most powerful straight-six engine BMW has installed in a racing car since the days of the BMW M1 Group 5,” added Ulrich Schulz, Head of Drivetrain Design, BMW Motorsport.

The S58 found in the production M4 Competition is designed to deliver maximum performance on the track and thus serves as the perfect platform for the race unit. Carried over components include the crankcase, cylinder head, crankshaft drive, crankshaft and connecting rods.

The transaxle design in the new BMW M4 GT3 is a sequential, straight-tooth 6-speed gearbox which is a development of the gearbox found in the BMW M8 GTE with improvements made in run time, cost efficiency and performance.

The clutch is electro-hydraulic for lower wear and is operated by steering wheel-mounted paddles. It features stall prevention and partially-automated start-up.

Wheels measure 12.5 x 18 inches front and 13.0 x 18 inches rear. The M4 GT3 has been tested with a wide variety of race tires to make sure that it is compatible with different manufacturers used in the various race series’ around the world.

The cockpit of the new BMW M4 GT3 features the latest FIA BMW M safety seat and new air conditioning with cockpit air circulation for significantly greater efficiency and vastly improved driver comfort. The air conditioning system in the M4 GT3 is easy to maintain and is twice as powerful as the system found in the M6 GT3. The steering wheel, pedals and center console can all be adjusted. There is dimmable illumination of controls and displays and the switches are arranged ergonomically for maximum driver comfort, especially during longer endurance races.

The cockpit allows for basic configuration of many systems without the need to connect a laptop or special software. Configurable systems include preselection of charging pressure graph, selection of series-specific functions, adjustment of pit speed, selection of fuel type, system diagnosis and sensor calibration.

In a transfer of technology between real and virtual motor racing, the steering wheel in the new BMW M4 GT3 was developed jointly by BMW Motorsport and sim hardware producer FANATEC. This revolutionary wheel is the first of its kind that works both in a real car and on a simulator.

It will go on sale to sim racers in the second quarter of 2021. Parallel to FANATEC commencing sales, a documentary film on the development of the hybrid steering wheel, which combines the worlds of real and digital motor racing, will be released on the Amazon Prime streaming platform.

“The first time I heard of the idea to design the BMW M4 GT3 steering wheel to be compatible with a simulator, I was flabbergasted – because I was thrilled by the concept from the word go,” said BMW works driver Philipp Eng, who demonstrated the steering wheel at BMW SIM Live 2020 and plays a main role in the documentary. “You have to take your hat off to the pioneering role that BMW Motorsport and FANATEC have taken on here, and to the courage to implement a project of this kind. I know the people who were involved in the development at BMW Motorsport and at FANATEC, and never doubted that they would design a superb steering wheel. It is very comfortable to hold. You can tell that real professionals have been at work in every area.”

The steering wheel includes activation of essential features such as traction control, radio, ABS, engine mapping, windshield wipers and the drink system.
