BMW has wowed audiences with this fantastic M4 GTS Concept, revealed at this week's Pebble Beach Concours event.
It follows in a long line of special edition M models, going back to the M3 Evolution of 1988.
Based on the standard M4 car, the GTS features bespoke touches including alloy-forged wheels and a carbon fibre reinforced plastic bonnet.
This track-focussed concept also has a manually adjustable front splitter and rear wing, both created from lightweight carbon fibre.
Despite all these additions, the GTS is still a fully-fledged road car, only with a reported 500bhp. Frank van Meel, president of BMW M Division, said: "Despite its outstanding track ability, it is still fully road legal. This is racing technology for the road in the truest sense".
The GTS also utilises a water injection system to provide more power and torque. This system was featured on BMW's M4 MotoGP Safety Car with great results. It boosts power whilst also reducing stress on the engine caused by heat.
Van Meel went on to point out that: "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."
Unit numbers for the previous-generation GTS were limited, so BMW is sure to set the figure for this latest model at a similarly small number.
