This weekend’s Pebble Beach Concours d’Elegance near Monterey, California is shaping up to be the unveiling venue-of-choice for a whole bevy of new luxury automobiles, with the latest announced guest being a new BMW M4 GTS concept.
Integral to novelty of this new concept – and what truly sets it apart from the production M4 – is a water-injection system with a 1.3-gallon tank. In essence, the system works by injecting a fine mist of water into the intake plenum during operation; when the water evaporates, it takes some amount of thermal energy out of the intake charge.
This means that the BMW M4 GTS has a substantially lower intake charge temperature than it would otherwise, allowing the engineers to dial-in more boost pressure and injection timing without risking detonation.
Also unique to this new BMW M4 GTS concept is a new hood which, apart from looking totally boss, is composed of carbon fiber-reinforced plastic for reduced weight. A new cooling system is comprised of a main radiator, plus a separate unit for the transmission, one for the turbochargers, and additional units for each the high- and low-temperature circuits.
Finally, as you may have spotted in the picture above, the BMW M4 GTS features an adjustable front splitter and rear wing, both made of exposed carbon fiber.
Beside offering customers the chance to easily optimize the balance between front and rear aerodynamic downforce, in a less practical sense, they state in no uncertain terms that the new BMW M4 GTS is mean, capable, and ready to hit the track.
