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.

BMW shows off 245-hp, hydrogen-powered 5 Series GT

With BMW's Innovation Days 2015 underway, the German luxury brand is showing off its latest piece of hydrogen-fuel-cell technology. Based in a 5 Series Gran Turismo, the system Í– co-developed with Toyota – promises to deliver on the promise of zero-emissions motoring, without the lengthy recharge times associated with plug-in electric vehicles. At the heart of BMW's latest FCV prototype is a new electric motor derived from the i sub-brand. It produces the equivalent of 245 horsepower, making it roughly comparable in output to the brand's latest 2.0-liter, turbocharged, four-cylinder gas engines. It draws its fuel from a hydrogen fuel tank that sits between the axles. The BMW-patented storage system can hold enough compressed hydrogen to take the hunchbacked 5 Series 300 miles before refueling. BMW and Toyota first inked their FCV partnership back in 2013, with the goal of having "an initial group of approved components ready by 2020," and sales beginning at some point in the next decade. While Toyota has been touting its successes with hydrogen in the form of the new Mirai, this 5 Series marks the first time since the agreement was signed that the German company rolled out one of its hydrogen-powered cars to the public. Check out the 5 Series GT fuel-cell vehicle in the gallery up top, and then scroll down for the official press release from BMW. Long range, short refuelling times, zero emissions: Hydrogen fuel cell drive system points the way to the future of BMW eDrive technology. As part of its research and predevelopment work in the area of drive technology, the BMW Group has focused on the use of hydrogen as an energy source for more than 30 years now. In 2006 the first luxury sedan for everyday use to be powered by a hydrogen combustion engine was unveiled – the BMW Hydrogen 7. And more than 15 years ago the BMW Group also began to direct its spotlight onto hydrogen fuel cell drive systems. A constant stream of significant advances – in terms of energy efficiency, performance capability and everyday practicality – have likewise been made with this technology, which converts hydrogen into power for an electric drive system, rather than burning it inside the engine. The results of the research and development activities in the field of hydrogen fuel cell drive systems will be presented in driving demonstrations for the first time during the BMW Group Innovation Days 2015.

BMW M4 Concept leaked ahead of Monterey debut

Last month, we heard that BMW might be bringing a concept previewing its next M4 sports coupe to this year's Monterey festivities. Well, thanks to the folks at USA Today, we have absolute confirmation of this by way of some leaked images. And goodness, she's certainly a looker.
While a few of us still find some of the 4 Series' design to be a bit awkward, it's hard to not immediately warm up to the aggressive bits of this hotter M4 concept. It certainly looks the business of a proper sports car, and a worthy successor to the M3 coupe. Of course, a lot of this will likely be toned down for the production version, which we'll likely be seeing at the 2014 Detroit Auto Show in January, along with its four-door M3 kin.
The official M4 Concept details will be revealed later tonight, but for now, have a look at a few shots of the golden show car in our gallery of leaked shots, above.
