Mercedes-Benz C-Class named 2015 World Car of the Year

It's been a good morning for Mercedes-Benz, with three of the company's wares taking home awards today at the New York Auto Show. The 2015 World Car of the Year awards have just been announced, and the charming new C-Class sedan has taken top honors, beating both the new Volkswagen Passat and Ford Mustang. But Car of the Year isn't the only award Mercedes received this morning. Here are the other World Car announcements, where M-B was honored two more times. World Performance Car of the Year: Mercedes-AMG GT World Luxury Car of the Year: Mercedes-Benz S-Class Coupe World Green Car of the Year: BMW i8 World Car Design of the Year: Citroen C4 Cactus Congratulations, all around, to this fantastic group of cars.

Tesla in talks with BMW about batteries, charging collaborations

With Toyota and Daimler no longer holding Tesla shares, the electric vehicle company might be looking for a new partner – possibly a Bavarian one. In a new interview with Germany's Der Spiegel, CEO Elon Musk confirmed that he has had talks with BMW execs about future collaboration. "We are talking about whether we can collaborate in battery technology or charging stations," Musk said in the interview, according to Reuters. However, a Tesla spokesperson has tempered things by saying no formal agreements are in place at the moment. In the same interview, Musk reportedly praised BMW's use of carbon-fiber-reinforced plastic in its i sub-brand offerings, and said he would like to have a battery factory in Germany in the next five or six years. The possibility of technological cooperation between Tesla and BMW has been a hot topic this year. In June, Musk reportedly met with BMW execs, and the two companies were also rumored to have met with Nissan to discuss charging technology. When Daimler sold off its shares, there was talk of it opening the way for possible collaboration between the two automakers, as well.

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.
