The much anticipated M4 GTS is scheduled to make an appearance at Pebble Beach, but it seems that BMW is too excited in sharing their new machine with the world. Designed specifically to preview the production model, the M4 GTS concept is given a Frozen Dark Metallic finish for the exterior and dashes of Acid Orange accents.
The hood is made out of carbon fiber reinforced plastic and has wider air intakes to optimize “airflow and minimizes front axle lift”. It is also given a front carbon fiber splitter, a carbon fiber rear wing, OLED taillights and lightweight forged alloy wheels.
What lies underneath that CFRP hood is a 3.0-liter TwinPower six-cylinder engine equipped with the water injection system which promises to increase power and torque figure. “The water is injected into the plenums of the intake manifold as a fine spray. When the water vaporizes, 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,” explained BMW.
Clearly cooling is a major area that BMW is looking into for the GTS Concept as aside from the main radiator it also has additional radiators for the high and low-temperature circuits, transmission and turbochargers.
