BMW M6 GT3

In 2016, the BMW M6 GT3 will replace the BMW Z4 GT3, which has been in action since 2010. The new car is powered by a 4.4-liter V8 engine with M TwinPower Turbo technology, which has been modified for use in motor racing. The power train has dry sump lubrication and generates up to 585 hp – with the whole car weighing less than 1,300 kilograms.

Further technical characteristics of the BMW M6 GT3 are the drive concept, six-speed sequential racing transmission, and high-performance motorsport electronics. The aerodynamic properties of the chassis have been optimised in the BMW wind tunnel. The engineers worked meticulously to fine-tune the BMW M6 Coupé, which formed the basis for the new car and was already perfectly suited to outings on the racetrack.

Priority was given to ensuring maximum driver safety. To offer the drivers of the BMW M6 GT3 as much protection as possible against the effects of an accident, BMW Motorsport itself developed and produced the FIA-approved safety cell in accordance with the very latest safety standards. The engineers also placed great importance on efficiency and ease of maintenance, as well as reliability, which is particularly crucial at the 24-hour classics. The development of the BMW M6 GT3 incorporated all the experience that BMW Motorsport gained with the car’s successful predecessor, the BMW Z4 GT3. For example, the new GT3 racing car boasts many improvements, particularly when it comes to driveability and economy. The positioning of the driver’s seat towards the centerof the car and the long wheelbase make driving the BMW M6 GT3 a unique experience in the world of motor racing.

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.

BMW M235i Racing – New top sports car for the “Green Hell”

BMW Motorsport is expanding its range of cars within the BMW Sports Trophy Customer Racing programme.

“The basis our engineers had to start with when developing the racing version of the BMW M235i Racing was exceptionally good,” said BMW Motorsport Director Jens Marquardt. “The production models from the BMW M Performance Automobiles range are already incredibly sporty. Because of this, we did not have to make many modifications in order to get the BMW M235i Coupé up and running as a racing car. BMW Motorsport can look back on a long tradition of allowing ambitious teams and drivers an affordable way into motor racing – and of offering them an absolutely competitive car. That was the case recently with the BMW M3 GT4, and that is now being superseded with the BMW M235i Racing. While the BMW Z4 GT3 spearheads our range, the new car means we are now also excellently positioned for the coming years in the field of production-based racing cars.”

The motorsport genes are also easily recognisable in the production version of the BMW M235i Coupé, courtesy of the aerodynamically optimised body design. It is propelled by the most powerful petrol engine developed so far for a BMW M Performance Automobile: a six-cylinder in-line engine with M Performance TwinPower Turbo technology. With a capacity of 2,979ccm, the racing version is capable of generating 333hp (245kW).

Motorsport-specific driving aids such as ABS, DSC and traction control ensure that the motorsport newcomers can also handle the BMW M235i Racing surely and safely. The car also comes with mechanical limited-slip differential, which is also available for the BMW M235i Coupé in the original BMW Parts range. The racing car is also fitted with features such as the FIA-certified safety cell and the modern safety tank. On top of this come components from the BMW M Performance Parts range, such as the rear and front spoilers, diffusor and carbon wing mirrors.
