If you try to remember last year Pebble Beach Concours dElegance you will find out that BMW used the event to unveil the new M4 performance coupe. The crowd was impressed, so BMW decided to take the stage this year also. This time with two impressive concepts. One of them is the M4 GTS, a tradition continuation of BMW M3 special models.
The BMW Concept M4 GTS showcases new technologies destined to make their series production debut in a new model to be unveiled at a later date. For example, the BMW Concept M4 GTS features the water injection system that has already provided a significant output and torque boost in the BMW M4 MotoGP Safety Car.
In addition, the BMW Concept M4 GTS has rear lights with OLED (organic light-emitting diode) technology that give the high-performance model a whole new look when darkness falls.
The 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.
The engine powering the BMW Concept M4 GTS is equipped with the same innovative water injection system that has endowed the BMW M4 MotoGP Safety Car with a noticeable increase in output and torque.
The BMW Concept M4 GTS is fitted with innovative rear lights featuring OLED technology. OLEDs (organic light-emitting diodes) are a new type of light source producing full-surface and homogenous illumination – in contrast to LEDs, which emit light to a single point. They have low installation height of just 1.4 millimetres.
The water injection system introduced by BMW M Division sees the engineers using the physical effect of water when vaporising to draw the required energy from the ambient medium. The water is injected into the plenums of the intake manifold as a fine spray. When the water vaporises, the intake air cools significantly. This technology ensures an increase in output and torque, while at the same time reducing the thermal stress on performance-relevant components.
