A year on from the launch of the BMW M4 Coupé, the BMW Group is presenting an initial preview of a high-performance model for use on the road and, above all, on the race track: the BMW Concept M4 GTS.
The new BMW Concept M4 GTS continues the tradition of spectacular BMW M3 special models: BMW M3 Evolution (1988), BMW M3 Sport Evolution (1990), BMW M3 GT (1995), BMW M3 CSL (2003), BMW M3 GTS (2010) and BMW M3 CRT (2011).
The dynamic and exclusive presence of the BMW Concept M4 GTS is highlighted by the exterior paint shade Frozen Dark Grey Metallic, with the Acid Orange accent on the front splitter and polished light-alloy wheels creating an effective contrast.
The BMW Concept M4 GTS is optimised down to the finest detail with a manually adjustable front splitter and rear wing – both in exposed carbon – ensure perfect aerodynamic balance and allow the BMW Concept M4 GTS to be adapted for both individual race tracks and for use on the road. Additionally, the engineers’ rigorous adherence to a lightweight design is evident with the CFRP (carbon-fibre-reinforced plastic) bonnet, which lowers the car’s weight and centre of gravity further still. A wide front air intake optimises airflow and minimises front axle lift.
The engine powering the BMW Concept M4 GTS is equipped with an impressive water injection system which generates a noticeable increase in output and torque. Water is injected into the plenums of the intake manifold as a fine spray. When the water vaporises, the intake air cools significantly. As a result, the final compression temperature in the combustion chamber – and therefore the engine’s tendency to “knock” – is reduced, enabling the turbocharged engine to use higher boost pressure and earlier injection timing.
The BMW Concept M4 GTS is fitted with innovative rear lights featuring OLED technology. OLEDs are a new type of light source producing full-surface and homogenous illumination. This technology enables extra flexibility and forges an unmistakable appearance that signals exceptional precision.
