BMW pays tribute with Z4 racing livery

Whether it's from Martini or BMW, there's something that makes us a little weak in the knees when we see a racing livery of dark blue, light blue and red stripes over white. Like the one on this BMW racer that will compete at Sebring next weekend. Presented alongside its spiritual predecessor at Amelia Island this weekend, this BMW Z4 GTLM has been decked out in a throwback version of the Bavarian automaker's iconic color scheme. It's a tribute to the BMW 3.0 CSL that scored the marque's first victory at the legendary Floridian endurance race 40 years ago and even wears the same number 25. It's as good a reason as any to bring back a racing livery we love, but then we'd probably take just about any occasion to appreciate it anyway. 40 years after the first win in Sebring: BMW presents anniversary design of the BMW Z4 GTLM for the 12-hour race. Munich (DE), 14th March 2015. On 21st March, BMW Team RLL will contest the 63rd staging of the legendary 12-hour race of Sebring (US) in the US state of Florida. The endurance classic is also the second race of the 2015 United SportsCar Championship (USCC). BMW Motorsport and BMW of North America celebrate a special anniversary on their return to Sebring this season: 40 years ago, BMW Motorsport got its first Sebring victory, with the BMW 3.0 CSL. In honour of that success, the two BMW Z4 GTLMs of BMW Team RLL will sport special designs as they compete on the "Sebring International Raceway". Car number 25 will carry the colours of the winning BMW 3.0 CSL of 1975. At an unveiling ceremony, which was part of the "Amelia Island Concours d'Elegance" in northern Florida, BMW of North America presented the anniversary design of the vehicles to the public for the first time. Many of the successful heroes of that time took the opportunity to attend the presentation. Forty years after the historic victory, then winners Brian Redman (US), Sam Posey (US) and Hans-Joachim Stuck (DE) were reunited on Amelia Island. Jochen Neerpasch, the first managing director of BMW Motorsport GmbH, and BMW Motorsport Director Jens Marquardt were also among the guests. They all had front row seats as current BMW Team RLL driver Bill Auberlen (US) completed the first presentation laps in the BMW Z4 GTLM with the anniversary design. 1975 was a significant year in the history of BMW in North America: BMW of North America was founded, and just a few days later came the historic first victory with the BMW 3.0 CSL in Sebring.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.
