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.

Toyota, Mercedes, BMW top automakers included in List of Best Global Brands

Interbrand, a consultancy firm, has published its 13th annual list of the best global brands. Besides seeing some shakeups at the top - Apple and Google unseated Coca-Cola (a company that has dominated the survey since its birth), the 100-item list features 14 automakers, most of which enjoyed double-digit gains in brand value.
Toyota managed to retain its spot as the study's top automaker. It finished the survey in 10th position overall (the same as last year), despite a 17-percent improvement in its brand value, from $29.33 billion to $35.34 billion. Mercedes-Benz, BMW and Honda all made the top 20, at 11th, 12th and 20th place, respectively. Hopping a ways down the list, we come across Volkswagen in 34th place, up from 39th in last year's study, with a brand value of $11.12 billion, a 20-percent improvement over 2012. Ford and Hyundai round out the automakers in the top 50, at 42 and 43.
Porsche made the largest year-over-year gain of any automaker, with its brand value increasing 26 percent to $6.47 billion. Chevrolet meanwhile, cracks the list for the very first time at 89th place. As Interbrand notes, Chevy's inclusion is notable because of the sheer number of vehicles it moves for General Motors and its recent push in developing markets. The final interesting note on this survey is the position of an automaker that takes its name and logo more seriously than perhaps any other - Ferrari. The Italian exotic manufacturer finished 98th out of 100, with just $4.01 billion in brand value, a six-percent improvement over 2012.

Which car should win 2015 World Green Car of the Year?

There were three finalists for the World Green Car of the Year announced about a month ago at the Geneva Motor Show: the BMW i8, the Mercedes-Benz S 500 Plug-In Hybrid and the Volkswagen Golf GTE. With the New York Auto Show upon us and the winner scheduled to be announced tomorrow, we thought it's high time to ask our readers which one should win. There were seven other vehicles named to the finalists list: the Hyundai x35/Tucson Fuel Cell, the Volvo XC90 T8 Twin Engine, the Audi A3 Sportback E-Tron, the BMW X5 xDrive40e, the Kia Soul EV, the Nissan e-NV200 and the Opel Adam 1.0 Direct Injection Turbo ecoFLEX Start.
