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.

Tesla only 8th greenest automaker, BMW is best, says Newsweek

We imagine some readers will be surprised by this. Newsweek has just put out its rankings for the top "green" companies in the world, and while Tesla Motors chief Elon Musk can crow about how green his electric vehicles are, the company as a whole apparently falls behind some traditional automakers. Quite a few of them, actually. In Newsweek's Global 500 list of the greenest 500 largest publicly-traded companies in the world, BMW ranked best among automakers at Number 26. Not surprisingly, Toyota was close behind at 35, while Nissan came in at 152. What's a little more puzzling is that Tesla fell behind Ford (178), and General Motors (289). That's a lot of pickups versus a few Model S EVs. Go figure. Then came Hyundai (306) and Honda (316), which are a little more palatable. Tesla? It came in at 431. Newsweek's measurement standards include eight categories that include a lot of verbiage and involve things like energy productivity (which is defined as revenue in US dollars divided by total energy consumption), greenhouse-gas emissions productivity (revenue divided by GHG emissions), water usage, waste levels and something called "green revenue" (revenue derived from products that "contribute positively" to the environment). Newsweek says that its results are reproducable by a third party. Take a look at the list here and find the details on how the numbers are compiled here.

BMW 3 Series Gran Turismo gets leaked well ahead of Geneva reveal

The great power of the internet has allowed us to get an early first look at the all-new BMW 3 Series Gran Turismo, a car that is slated to be shown in full at the Geneva Motor Show next month, albeit without many details to go on right now. With pictures leaking out this early in the game, we'd expect that you won't have to wait until March to get the full lowdown, however.
Our first look at the 3er GT reveals a car that is, to our eyes, a tidier piece of design work than its 5 Series GT brother. The long-backside proportions are still a bit ungainly, at least from these images, but they're helped tremendously with the larger wheel/tire package and more aggressive fascia of the sport package.
Expect the 3 Series GT to hit the ground running, with the same turbocharged 2.0-liter four-cylinder and 3.0-liter inline-six found in the standard 3 Series sedan. BMW's popular xDrive all-wheel-drive system is a virtual lock for the option sheet, too.
