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 could add all-electric Mini, X3 SUV

BMW's Mini sub-brand will add a battery-electric variant as the company looks to meet stricter emissions mandates around the world, according to an interview Bloomberg News conducted with CEO Harald Krueger. BMW is also planning an all-electric version of its X3 SUV and may start greening up models as large as its 7 Series sedan, though that prospect is far cloudier. The all-electric Mini will be available to the public as soon as 2019, while the battery-electric X3 SUV will likely start sales the following year. BMW didn't offer specifics about how much those models would cost or far they will be able to travel on a full electric charge, with Krueger only saying single-charge ranges would be "competitive" with other all-electric models. BMW this summer upgraded the battery in its i3 electric vehicle and boosted its single-charge range by about 40 percent to 114 miles. As for demand for BMW's i sub-brand vehicles, US sales of the i3 through September fell 27 percent to almost 5,800 vehicles, while sales of the i8 plug-in hybrid are down 19 percent to about 1,100 units, BMW said on Monday. Meanwhile, word got out earlier this year that BMW may dedicate the Rocketman concept hatchback as Mini's entrant to the electric-vehicle sector. BMW actually used a Mini as its first electric testing vehicle. The Mini E was produced in 2009 and 2010 before giving way to the BMW ActiveE, which was actually a converted 1-Series vehicle. Eventually, BMW started producing the i3. Related Video: Featured Gallery Mini Rocketman Concept View 25 Photos News Source: Bloomberg News Green BMW MINI SUV Electric

Rolls-Royce sketching out SUV for possible 'late 2017' release

With each new story on the Rolls-Royce SUV, the Goodwood automaker comes off as more at ease with their reluctantly birthed yet necessary sport ute. Company design chief Giles Taylor told Autocar that his team is still "sketching to assess the viability of the concept," which to ours ears means they're trying to figure out if such a beast is even possible within the confines of the brand. If it is, Taylor says it will be "a shooting brake, not a crossover with a sloping roof. A proper SUV."
A different company source, unnamed, seems confident that Taylor's team will figure it out, telling the magazine it would start at 200,000 pounds ($335K US). However, that same source said the vehicle will be "a kind of Mercedes-GLK-plus-plus," which is a baffling description in several ways. More reasonable is the speculation that it will ride on Ghost, not Phantom, architecture and make its debut sometime around late 2017.
That Ghost platform is expected to take cues from the carbon, aluminum and steel bones that supported the BMW Vision Future Luxury concept shown at the Beijing Motor Show and destined for the 9 Series. Some of those tricks will also go into the next-generation Phantom, which Autocar says will come in 2017 and not 2020.
