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.

BMW i Collection puts upscale treehugging in the palm of your hand

If BMW's new i sub-brand sounds more like it belongs to consumer electronics than it does to automobiles, that's probably no mistake. After all, electric vehicles bridge the gap between conventional automobile and electronic gadget - just ask our compatriots over at Engadget that report on them all the time. But to drive the point home even greener, BMW has, together with the new i3, launched a new collection of electronics accessories that make the Bavarian automaker as much a competitor with companies like Belkin or Griffin as it is with Audi or Mercedes-Benz.
The new BMW i Collection includes items like a solar charger for phones and MP3 players, a laptop bag made from felt-like recycled PET plastic and vegetable-tanned leather, and of course the requisite USB dongle. Other items include keyfobs, a shopping bag, notebook and ballpoint pen.
All the items, of course, are designed to extend the i3's upscale tree-hugging image to items you can hold and use while your EV is charging in the driveway. They go on sale starting next month with prices ranging from 15 euros ($20) for the pen or lanyard to 99 euros ($135) for the shopping bag. Details in the press release below and images of the whole collection in the gallery above.

BMW bringing X3 diesel, X5 PHEV concept to New York

We've seen the i3 and i8 plug-in vehicles at plenty of BMW auto show stands these past few years. At the upcoming New York International Auto Show, the automaker will spread out a bit by showing off both new diesel and plug-in hybrid SUVs. Bimmer will showcase its diesel-powered X3 vehicle, which starts sales this spring as a 2015 model, and a concept plug-in hybrid X5 SUV. There are lots of figures to digest for what will be called the X3 xDrive28d. The vehicle will be powered by a 2.0-liter four-cylinder twin-turbodiesel engine that will deliver 180 horsepower and 280 pound-feet of torque. Propelled in part by an eight-speed automatic transmission, the SUV will be able to go from 0 to 60 miles per hour in about eight seconds. It will be priced with an MSRP of $42,825, which is represents a $3,500 premium over the base X3. BMW hasn't made fuel efficiency figures available, but they should be a nice improvement over the base X3's 24 mile per gallon fuel-efficiency rating in the US. Bimmer is also supposed to bring the X5 eDrive concept plug-in hybrid stateside. We saw it in Frankfurt last fall and then in some on-the-road spy shots more recently. The SUV pairs a 245-horsepower four-cylinder gasoline engine with a 95-horsepower electric motor, and will be able to go as fast as 75 mph and as far as 20 miles on electric power alone. BMW says fuel efficiency will be about 62 miles per gallon, per the more lenient European Union test cycle. That's more than double the current diesel powered X5's 26 combined mpg rating handed out by the EPA. And the model's 0-60 time is less than seven seconds. If you'd like to know more, you can take the better part of the day and check out Bimmer's mighty long press release below.
