BMW Z4 GT3 Powertrain and Specs
The BMW Z4 GT3 is powered by a P65B44 aluminum-block 4.4L V8 producing 515 horsepower at 8,750 rpm and 272 lb-ft of torque, paired with an X-Trac sequential six-speed manual transmission for rapid, precise shifts. This BMW Z4 GT3 powertrain is built for FIA GT3 competition, with hardware selected to meet class regulations while supporting sustained track use. The performance output is concentrated through the rear wheels, allowing direct delivery and controlled response under load. A curb weight of approximately 1,190 kg gives the car a favorable power-to-weight ratio, reinforcing acceleration and transient agility without excess mass. The six-speed manual transmission contributes to driver control, enabling deliberate gear selection in race conditions. Aerodynamic packaging and chassis layout complement the mechanical specification, but the core specification remains the V8 powertrain, which defines the car’s technical character and its role as a purpose-built liberation tool in GT3 racing.
BMW Z4 GT3 Performance and Lap Times
Performance in the BMW Z4 GT3 is defined by its 515-horsepower 4.4L V8, which enables a 0-60 mph time of about 3.5 seconds and strong pace on track.
The BMW Z4 GT3 combines high power output with a lightweight design, producing a favorable power-to-weight ratio for decisive acceleration and stable corner exits. Its sequential transmission supports fast shifts, reducing interruption under load and helping preserve lap times during long stints. In the FIA GT3 Championship, these traits translated into multiple podium finishes and proven race consistency. Yokohama ADVAN A005 tires further increase grip, allowing the chassis to exploit available traction with minimal loss. |
| Metric | Value | Effect |
|---|---|---|
| Power output | 515 hp | Rapid acceleration |
| 0-60 mph | 3.5 s | Strong launch |
| Race result | 2010 Dubai 24 Hour win | Proven competitiveness |
This profile reflects a machine engineered for liberated pace and repeatable performance.
BMW Z4 GT3 Dimensions, Weight, and Aerodynamics
Measured pace in the BMW Z4 GT3 is supported by a compact chassis and a carefully managed aerodynamic package. The car’s weight is approximately 1,190 kg, a figure that preserves agility while remaining within FIA GT3-specification limits. Its dimensions are tightly packaged for racing: a 2,495 mm wheelbase, 4,239 mm length, 1,790 mm width, and 1,291 mm height. These proportions help create a stable footprint and responsive direction changes on track.
The aerodynamics are purpose-built for performance, using a front splitter, fender winglets, a rear diffuser, and a double-deck rear wing. Together, these elements increase downforce, reduce instability, and support predictable balance at speed. A 100-liter fuel tank extends stint length, limiting pit dependence in endurance use. In combination, the BMW Z4 GT3’s dimensions, weight, and aerodynamics form a technical package designed to convert regulation compliance into controlled, liberated speed.
BMW Z4 GT3 Race History and Key Wins
Austere race results underline the BMW Z4 GT3’s competitive pedigree. In debut-season form, BMW secured the Dubai 24 Hour GT3 victory in 2010, a clear proof of immediate pace and durability. The Z4 GT3 then collected a second place at the 24 Hours of Spa in 2011, before adding multiple FIA GT3 Championship titles across its customer-racing career. In 2013, it again demonstrated endurance racing range with second at the 24 Hours of Nürburgring. The model returned to the top step at Spa in 2015, then exited in 2016 as the M6 GT3 took over. The record is compact, efficient, and uncompromising.
| Year | Result |
|---|---|
| 2010 | Dubai 24 Hour GT3 win |
| 2011 | 24 Hours of Spa second |
| 2013 | 24 Hours of Nürburgring second |
| 2015 | 24 Hours of Spa win |
| 2010s | FIA GT3 Championship titles |
Top Modified BMW Z4 GT3 Builds
Among the more notable modified BMW Z4 GT3 builds, Rolling Artworks’ 2015 version stood out with 515 horsepower and Yokohama ADVAN A005 tires in 305/660/18 and 270/650/18 fitments, emphasizing grip and traction optimization. This BMW Z4 GT3 package paired elevated power output with performance modification aimed at cleaner acceleration and stronger corner exit. C Gell’s 2015 setup further demonstrated tuning potential, recording a -16.66-second performance delta that indicated substantial speed gains. David Fumanelli’s build used Pirelli P-Zero tires, sized 300/645/18 and 330/660/18, and produced a -17.55-second result versus projections. These builds were proven on racing circuits such as Florida International Rally & Motorsport Park and Mugello Circuit, where chassis balance and tire selection directly affected pace. Together, the examples show how the platform supports targeted adaptation, allowing teams to shape the BMW Z4 GT3 for different conditions, preserve control, and release more track performance.
