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.

Jeep Grand Cherokee, BMW i8, Ford F-150 win 2015 Green Car Awards in DC [w/video]

There were three shiny trophies handed out at the Washington Auto Show last week by Green Car Journal, and they went to three different examples of what "green" means in the automotive industry today. The Jeep Grand Cherokee EcoDiesel won the award for the 2015 Green SUV of the Year, the BMW i8 was named the 2015 Luxury Green Car of the Year and the Ford F-150 took the 2015 Green Car Technology Award honor. There is a case to be made that the aluminum body of the new Ford truck will make a bigger impact in the overall fuel usage in the US than almost any other vehicle, given the numbers of F-150s that Ford sells each year. The B20 biodiesel-capable Jeep gets up to 30 miles per gallon on the highway. And the i8 puts all sorts of new, fuel-saving technologies into an attractive package. Looking over the winners, and the list of finalists you can see in our photo gallery, and you can see that the definition of green is expanding every year. You can watch Green Car Journal editor Ron Cogan hand out the 2015 awards in the video below and we'll for sure be paying attention to what wins next year. 2015 Luxury Green Car of the Year, Green SUV of the Year and Green Car Technology Winners Announced WASHINGTON, Jan. 22, 2015 /PRNewswire/ -- Green Car Journal has named the Jeep Grand Cherokee EcoDiesel its 2015 Green SUV of the Year™ and the BMW i8 its 2015 Luxury Green Car of the Year™, with the aluminum-bodied Ford F-150 earning the magazine's 2015 Green Car Technology Award™. Winners were determined by a jury of Green Car Journal editors and automotive experts. The prestigious awards were announced in Washington, D.C. today at a Green Car Awards™ press conference held during the Washington Auto Show's Public Policy Day at the Washington Convention Center. "These are truly commendable vehicles representing the 'best-of-the-best' in so many ways," said Ron Cogan, editor and publisher of the Green Car Journal and CarsOfChange.com. "The auto industry's very early focus on small cars and efficiency-for-environment tradeoffs has evolved to now include a more dynamic field of 'greener' models in all vehicle classes. Those wanting greater efficiency or better environmental performance are no longer constrained by limited choices or vehicle types that fall outside their top purchase preferences.

2014 BMW 320i

When BMW switched its entry level 3 Series, the 328i, from a naturally aspirated, 3.0-liter six-cylinder to a turbocharged, 2.0-liter four-cylinder, we weren't entirely sure what to think. Sure, from a pure numbers perspective, the new 2.0-liter cooked the old 3.0's goose, delivering more torque at far more accessible engine speeds while boosting horsepower and fuel economy.
While we miss that revvy six-pot, the numbers for the 2.0 were just way too good to pass up. Then we received news of an even less-powerful 2.0-liter 3 Series - the 320i. This was interesting, as it saw BMW delving into a power level previously owned solely by the anemic Lexus IS 250 and its six-cylinder engine.
Could BMW make a sub-200-horsepower sedan that still drove the way we expected a 3 Series to drive? To find out, we borrowed the new 320i for a week of testing.
