BMW details track-only M4 GT4by Ronan Glon
The M4 GT4 will make its competition debut next year.
BMW has introduced the track-only M4 GT4 after a long teaser campaign. The race car will make its public debut this weekend at the Nurburgring 24 Hours race, though it's not officially competing in the event.
Power comes from a 3.0-liter straight-six engine that's turbocharged and direct-injected. The GT4 is the first BMW race car compatible with power sticks, meaning teams can dial in the precise amount of power they need and plug the settings directly into the ECU. The six makes 430 horsepower in its most basic configuration, and it exhales through a GT4-specific exhaust system.
A seven-speed dual-clutch automatic transmission channels the engine's output to the rear wheels, while six-piston front calipers borrowed from the bigger M6 GT3 safely bring the action to a stop. The long list of suspension modifications includes special shock absorbers, springs with three settings, adjustable stabilizer bars, and a motorsport-specific dynamic stability control (DSC) system.
To shed weight, BMW manufactured the doors, the hood, and most of the body kit out of carbon fiber. The cabin has been pared down to just a driver's seat, a rectangular steering wheel, a digital instrument cluster, and a GT4-specific center console.
The BMW M4 GT4 is on-sale now. Pricing starts at 169,000 euros in Germany, a sum that represents about $190,000 at the current conversion rate. Deliveries will start before the end of the year, and the GT4 will start racing next year.
