Mmmmm… what a concept

BMW Concept M4 GTS (800x599)

New BMW M4 GTS giving adrenaline-fueled high performance for the road and race-track

A year on from the launch of the BMW M4 Coupe, the car-maker is now 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 move sees BMW M Division once again returning to its roots. The BMW offshoot, founded in 1972 as BMW Motorsport GmbH, not only caused a sensation with its iconic BMW M1 racing car, but developed the first turbocharged engine to win the Formula One World Championship and was the force behind what remains the world’s most successful racing touring car – the Group A BMW M3.

The BMW Concept M4 GTS showcases new technologies such as the innovative 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 dynamic and exclusive presence of the BMW Concept M4 GTS is accentuated by the exterior paint shade Frozen Dark Grey Metallic, with the Acid Orange accent on the front splitter creating an effective contrast. The lightweight, forged and polished light-alloy wheels in 666 M styling also feature an Acid Orange accent. The 9.5 J x 19 (front) and 10.5 J x 20 (rear) wheels are fitted with Michelin Sport Cup 2 tyres (265/35 R19 at the front, 285/30 R20 at the rear). The mixed-size tyres provide the ideal conduit for the stand-out dynamic attributes of the BMW Concept M4 GTS.

The water injection system introduced by BMW M Division sees that 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.

This technology ensures an increase in output and torque, while at the same time reducing the thermal stress on performance-relevant components. All of which also enhances the stability and durability of the turbocharged engine.

The strong performance potential of the turbocharged six-cylinder in-line engine already demands an exceptionally sophisticated thermal management system for the engine and ancillary units.
