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. Would you have named one of these to the top three list instead? POLL 14386429 Green BMW Mercedes-Benz Volkswagen 2015 ny auto show world green car of the year vw golf gte

BMW M235i Racing takes to the track

Last month, BMW showed off a motorsports version of its new 2 Series Coupe called the M235i Racing. While that single image was obviously a rendering or design model, BMW Motorsports has now released a video showing the real deal being tested.
From what we can tell from beneath the camouflage, the wide-body fenders ­- to accommodate a 3.5-inch track stretch - are slightly different than the image BMW previously released. Still, the body is noticeably different from the stock coupe. The video, which is posted below, shows glimpses of the race-prepped interior, including a full FIA roll cage, but more importantly we get to hear the 333-horsepower engine and its throaty exhaust in action.

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.
