At the same time, the sharpest BMW M4 of all, can also hold its own on public roads. BMW is making available the BMW M4 GTS in a special edition limited to 700 units to celebrate the 30th anniversary of the BMW M3, which has been in production since 1986. In so doing, it is highlighting the innovative flair of the BMW M engineers in developing trailblazing M technologies on the powertrain, chassis and lightweight construction front.
The BMW M4 GTS uses the multi-award-winning six-cylinder inline turbo engine from the BMW M3/M4, but adds innovative water injection technology to give the 3.0-liter unit a substantial power boost. The water injection system raises the engine’s output significantly to 500 hp (368 kW) and increases torque to 600 Nm (442 lb-ft), yet still keeps fuel economy and CO2 emissions at the level of the BMW M4 Coupe (8.3 liters per 100 km, 194 g/km). This makes the BMW M4 GTS the most agile, radical and dynamically potent variant in the range. It races from a standstill to 100 km/h (62 mph) in a mere 3.8 seconds and hits a limited top speed of 305 km/h (189.5 mph).
Intelligent lightweight construction allows the BMW M engineers to limit the car’s DIN kerb weight to 1,510 kilograms (ECE kerb weight: 1,585 kg). Its outstanding weight-to-power ratio of 3.0 kg/hp provides the perfect platform for a highly dynamic driving experience. The rigorous weight-saving measures extend through both the interior and exterior of the car. Inside, carbon-fiber bucket seats, a lightweight center console, the lightweight construction of the rear seat panelling and boot area partition, and special lightweight door and side panel trim, including door pull loops in place of solid door handles, are clearly visible indications of the designers’ commitment to weight-saving.
The standard-fitted 7-speed M Double Clutch Transmission (M DCT) selects the optimum ratio for every driving situation with no interruption in the flow of power as it makes its way to the rear wheels. The driver can also select gears manually using either shift paddles on the steering wheel or the selector lever. The Drivelogic shift programs and Launch Control have been re-tuned to the engine’s increased output.
The three-way M coilover suspension specially tuned for the BMW M4 GTS can be adjusted to individual tastes and therefore also to the demands of different race circuits. The lightweight M carbon ceramic brakes offer a well-defined pressure point and ensure outstanding deceleration even under sustained heavy loads, such as at the limit on the race track.
The familiar two sets of twin circular headlights with four corona rings ensure the best possible illumination of the road surface. They combine cutting-edge LED (light-emitting diode) technology with BMW Selective Beam (dazzle-free high beam assistant) and Adaptive headlights. Rear lights are made up of L-shaped OLEDs (measuring just 1.4 millimeters in height). What’s more, the rear lights underline the width of the rear end, lend the car an even more eye-catching and powerful appearance and ensure it cuts a stand-out figure in both the light and dark.
Moving to the inside, there are the carbon-fiber, lightweight M bucket seats, lighter than those in the M4 Coupe, with Alcantara/Merino and M stripes on the backrests, three-point seat belts and door pull loops. The M Sport steering is made up of Alcantara,and in place of a rear seat bench, the BMW M4 GTS features a GFRP (glass-fiber-reinforced plastic) shelf and a rear panel in carbon-fiber sandwich construction. Both are covered in Alcantara, and together they enable a weight saving of around 40 per cent. Options to decked the M4 GTS into a track ready beast include the Clubsport Package, which includes a roll bar in Acid Orange behind the front seats, a race-specification six-point harness and a fire extinguisher.
The first high-performance special edition in the M3/M4 range is slated to be made available for the North American market; for the first time.
