BMW Concept M4 GTS previews track-focused future production car
One of the hottest introductions at the Monterey Car Week was the tantalizing BMW Concept M4 GTS. An exercise that the company says "showcases new technologies destined to make their series production debut in a new model to be unveiled at a later date," this supercoupe raises the performance bar of the M4 to higher levels.
"While the BMW M4 Coupe embodies the ideal combination of motor sport genes and unrestricted everyday usability, 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," said Frank van Meel, president of BMW M Division at the reveal. "Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense."
At its heart, the Concept M4 GTS features a modified 3.0-liter twin-turbo inline-6 engine fitted with the water-injection system BMW has been testing on the M4 Safety Car used in the MotoGP motorcycle racing series. This technology, which injects a mist of water into the intake plenum to cool the incoming air and reduce compression temperatures - allows for higher boost and enhanced timing which lead to increased power and torque. At the same time, it reduces thermal stress levels on various internal components. Water injection also improves fuel economy by up to eight percent. To further leverage its water injection setup, the Concept M4 GTS employs a cooling system that mates the main radiator with supplemental units for the transmission and turbocharger to maintain stable operating temperatures.
Finished in Frozen Dark Grey Metallic with Acid Orange accents, the Concept M4 GTS makes a bold back-to-the-track statement. The car sports a deep front splitter and prominent rear wing, both manually adjustable and rendered in exposed carbon fiber. The aggressively styled, aero-optimized nose of the Concept M4 GTS also has a CFRP (Carbon Fiber Reinforced Plastic) hood that trims weight and helps lower the center of gravity while the aft quarters features unique details of its own, including a more functional lower diffuser and new OLED (Organic LED) taillamps. More compact than conventional LEDs and producing full-surface, homogeneous illumination, BMW touts this technology a precursor to distinctive new lighting designs on its upcoming models. Rounding out the functional mix are a set of staggered size -- 19-inch front/20-inch rear -- lightweight alloy wheels wrapped in Michelin Sport Cup 2 performance tires.
While BMW has yet to officially confirm its plans, a limited-production version of the M4 GTS is expected to go on sale here sometime in 2016.
