New 2016 BMW M4 GTS available for the first time in the US.

BMW today announced the new 2016 BMW M4 GTS giving BMW M GmbH a new and exclusive technological masterpiece which elevates the potential of the BMW M4 Coupe to an impressive new level. With its powerful, motorsport-inspired looks and high-performance technology, the BMW M4 GTS has its sights set squarely on the race track. Thanks to an innovative water injection system helping boost power to 493 bHP and track ready chassis, this Special Edition M vehicle recorded a lap time of 7 minutes 28 seconds around the legendary Nürburgring-Nordschleife, the world’s most challenging race circuit, making a clear statement about this model’s exceptional dynamic abilities. At the same time, the sharpest BMW M4 of all can also hold its own on public roads. BMW M GmbH is launching the BMW M4 GTS in a special edition limited to 700 units worldwide, with 300 units of this high-performance Special Edition M4 available for the first time in the US market. In so doing, it is highlighting the innovative flair of the BMW M engineers in developing trailblazing M technologies on the powertrain, chassis and lightweight construction fronts.

The engine develops its maximum power of 493 bHP – an increase of 16 percent over the BMW M4 – at 6,250 rpm. Peak torque has been increased by 10 percent to 442 lb-ft, and is maintained over a very wide rev band (4,000 rpm to 5,500 rpm). It accelerates from a standstill to 60 mph in a mere 3.7 seconds, on the way to a governed top speed of 189.5 mph. Despite the significant extra power, the engine also excels on fuel efficiency, providing similar levels to those found in the BMW M4 Coupe.

“Special Edition models sharpen the character of the BMW M brand and embody an emotionally rich and exclusive driving experience. We’ve taken a radical route with the set-up of the BMW M4 GTS to create a sports machine for the race track that delivers top-end dynamics and inspirational performance. It allows us to demonstrate what is possible today with a road-legal car. Owners can drive their BMW M4 GTS to circuits such as Spa-Francorchamps, the Nürburgring or Laguna Seca – for clubsport events, for example – and then set lap times there that raise the bar to extremely high levels for road-legal cars.” says Frank van Meel, CEO of BMW M GmbH.

BMW M4 Safety Car Debuts with Water Injection

BMW M division previews new water injection technology in the latest iteration of the BMW M4 Safety car.  Water injection while interesting in theory has its ups and downs.  A big downer typically is reliability.  However, when it works, it can provide substantial gains through the use of vaporizing water in an intake plenum to cool the intake charger after the heat exchanger becomes heat soaked. The water injection allows for more efficient charge air cooling and sensitive components can be operated with a higher boost pressure.  Water injection works by injecting a fine spray of water into the collector which will lower the tendency of the engine to knock, thus enabling the point of ignition to come closer to the optimum value.

As a method to reduce the temperature of the intake air of the new BMW M4, BMW developed a solution to inject a fine spray of water into the intake manifold which will lower the tendency of the engine to knock, thus enabling higher boost pressures and maintaining an optimum ignition point.

As a consequence, this creates a more effective combustion process and at the same time it diminishes the combustion temperature. Since the cool air has a higher density which increases the oxygen content inside the combustion chamber, this means the higher pressure during the combustion process will improve performance and torque. Moreover, the lower thermal strain on the components will increase their lifespan.

The necessary water is stored in a frost-proof five-liter tank located in the M4’s trunk which also incorporates the water pump, sensors and valves which are controlled by the engine’s electronics. The pump feeds water into the injectors at a ten-bar pressure while the volume of water provided depends on the load, engine speed and temperature in order to grant optimal water consumption. BMW M says the water tank must be refilled before any “rigorous action out on the racetrack” while in normal driving on public roads they estimate a water refill once every five stops for refueling without requiring any extra maintenance.

The new water injection allows for outstanding driving properties and impressive performance parameters on the race track for those who demand the most of their M4.
