PROJECTS
GTM 4.4 combines the M4 F82 architecture, the S63 V8 from the M5 F10, selected original BMW M4 GT4 hardware and GTM system integration in one complete vehicle.

The BMW M4 is the starting point. GTM 4.4 is the product.
Powertrain, chassis concept and vehicle setup come together as one product and form the common foundation for every GTM 4.4 build.
The compact proportions of the M4 meet the power delivery of BMW’s S63 V8. This distinctive combination defines GTM 4.4.
Engine, transmission, cooling, electronics, suspension, brakes and aerodynamics work toward the same performance objective. Their integration determines how the car behaves under load.
Colour, interior, seats and selected body details can be specified individually within the GTM 4.4 concept.
Documented suspension, braking, wheel and aerodynamic components provide a genuine technical foundation that GTM integrates and calibrates as part of the complete vehicle.
P01 has been tested and developed at MotorLand Aragón, Portimão, Estoril, the Nürburgring Nordschleife and Barcelona-Catalunya, with professional-driver feedback informing each phase.
Power delivery, suspension, geometry and other parameters can be calibrated around driver level, driving style, circuit characteristics and intended use.
Measured data, build records, testing on five circuits and P01’s German individual approval make its development history traceable.
Depending on scope and country, this can include specification, build, setup, technical preparation, registration support, logistics and delivery.
Maintenance, repairs and consumables are considered alongside the specification and intensity of track use.
Each GTM 4.4 follows a defined vehicle concept, with selected details tailored to its owner.
M4 F82 platform, S63 V8, defined drivetrain concept, system integration, safety and quality standards.
Colour, interior, seats, selected material and body details, ergonomics, geometry and final setup.
Donor condition, country, legal route, transport, service and support are assessed for each vehicle.

P01 combines the 4,395 cm³ S63B44B V8 from the M5 F10 with the associated 7-speed M-DCT and rear-wheel drive. Packaging, mounts, electronics and cooling are developed as an integrated system.
Documented BMW M4 GT4 suspension components and Uniball joints support precise camber, toe and chassis response. Their component origin does not make GTM 4.4 a GT4 racing car.
The front uses documented BMW/AP Racing M4 GT4 six-piston hardware with 390 × 33.5 mm discs and cooling ducts. The rear uses an AP Racing four-piston system with 380 × 28 mm discs.
According to GTM’s engineering team, the M5 cooling system is adapted to the M4 and supplemented by DO88 components. Differential-oil cooling and a fuel surge tank help manage temperature and fuel supply under sustained load.
P01 uses a documented BMW M4 GT4 front splitter and rear wing together with selected carbon panels. The design follows the intended function rather than an appearance package.
The documented cage, seats and vehicle integration form part of the complete P01 architecture. Prototype P01 completed the German individual-approval process under §21 StVZO.
Track testing, vehicle data and setup adjustments document how P01 has been developed.

GTM’s documentation process brings together the vehicle number, specification, test history, setup, handover and service records. The second GTM 4.4 is in development and will be used to establish a repeatable build process.
The documented status belongs to Prototype P01. It does not automatically transfer to another build or another market. Every future project requires its own technical and legal assessment.
Selected documented BMW M4 GT4 components are integrated within GTM 4.4. GT4 describes the origin of those components. GTM 4.4 is an independent track tool outside the GT4 racing-class formula.
These figures and components describe P01, based on vehicle records and GTM engineering information. Future builds are assessed and documented separately.
Familiar BMW systems support servicing and parts sourcing. Maintenance is planned around the demands of track use.
For P01 track use, GTM’s engineering team gives provisional oil-change intervals of 1,000 km for the engine, 2,000 km for the differential and 3,000 km for the M-DCT. These are reference values, not a final service schedule.
A suitably connected laptop can transmit fault codes and sensor data for remote diagnosis. Availability and scope are agreed for each project.
Noise, heat, direct feedback and consumable wear reflect P01’s intended use and are considered during handover.
The next GTM 4.4 is in development. Intended use, experience and country of use are clarified before a specification is proposed.
Tell us what you drive, where you use it and what you expect from the next vehicle.
Intended use, country of use, driving experience and priorities are defined before a specification is discussed.
Qualified prospective clients can be invited to meet the team and experience P01 in the Nürburgring region.
Scope, specification, legal route and delivery are defined for the individual vehicle.
The location keeps the development loop short: inspect, adjust and return to the circuit. P01 is the result of specialist engineering and real track use in that environment.
P01 combines the F82 vehicle identity, the M5 S63 powertrain, selected BMW M4 GT4 components and GTM integration across packaging, cooling, fuel, electronics and approval.
Yes. Prototype P01 holds individual approval in Germany under §21 StVZO. This status does not automatically transfer to another build or country.
No. GTM 4.4 is an independent track tool without GT4 homologation. The GT4 designation refers to the origin of selected documented components.
The core technical concept remains consistent. Colour, interior, seats, selected body details, ergonomics, geometry and final setup are tailored to the owner and intended use.
Tell us about your intended use, driving experience and country of use. We will get back to you to discuss the next step.
