New M4 GT3 Introduced
BMW Motorsport is proud to announce the new state-of-the-art BMW M4 GT3 customer race car based on the recently launched 2021 M4 Competition Coupe. Powering the new Coupe is the P58 3.0-liter inline6-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 eight 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. (You are welcome to bring to a Club HPDE, too—Libby.)
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 tank 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 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.
