BMW's M Division has officially unveiled the first track-focused M4 in the market called the M4 GTS. The thinly veiled concept car is set for its first public appearance in Pebble Beach. According to BMW, the M4 GTS concept continues the BMW M3 tradition of making track-oriented models that started with the E30 M3 Evolution, followed by the E30 M3 Sport Evolution , E36 M3 GT, E46 M3 CSL, E92 M3 GTS and E90 M3 CRT.
Now called the F82, the M4 GTS concept gets a BMW Individual Frozen Grey paint finish with Acid Orange accents on the front splitter and bespoke wheels. The GTS concept also gets a carbon-fiber reinforced plastic hood and blacked-out kidney grills. A pair of extra intakes are said to “optimize airflow and minimizes front axle lift." while the carbon-fiber front splitter rounds up the changes done to the front of the car. At the back, the M4 GTS concept gets a carbon fiber rear wing and OLED taillights. The M4 GTS concept rides on lightweight forged alloy wheels measuring in at 19 inches in front and 20 inches at the back.
Apart from downforce upgrades, the M4 GTS concept recieves tweaks under the hood. While the 3.0 liter, twin-turbocharged engine is shared from the standard M4, The GTS concept recieves a water injection system. The system was first applied in the M4 MotoGP safety car which isn't available to the public. According to BMW, "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."
“The BMW Concept M4 GTS previews an emotionally powerful and exclusive special model conceived with an eye for trailblazing technology and a keen focus on the race track. Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense.”, said Frank van Meel, President of BMW M Division.
