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: i8 sold out, i3 records 10k orders

Just in case anyone was wondering how plug-in BMW cars would be received, the answer is apparently "quite well." After speaking with BMW's global sales chief last week at the LA Auto Show, Reuters has learned that the plug-in hybrid i8 sports coupe is already sold out for its first year on the market.
There is no word as to how many i8s BMW sold, but the first example was delivered to a customer last week in Germany. As for the all-electric/range-extended i3 hatchback, the automaker has received more than 10,000 orders for this model before it even goes on sale. Likewise, we don't know how many BMW plans to sell, but we do know they'll be showing up in the US before next summer.
We've already spent some time behind the wheel of both plug-in BMWs, and you can check out our first drive of the production i3 and our first drive of an i8 prototype.

Refreshed BMW 6 Series sports an understated redesign in Detroit [w/video]

BMW is keeping its refresh for the 2015 6 Series family very subtle. The tweaks amount to an understated nose job for the luxury models and some new standard tech, as well. The Bavarian brand is definitely not going too far with this redesign for the vehicles, and they even remain mechanically the same. The most obvious change for the latest 6 Series models is the sharpened front end. BMW explains that the grille now features nine slats, rather than ten. Clearly, this is a major change in design. The lower air dam is slightly reworked to accentuate the vehicles' width, and, in addition, the four-door benefits from a tweaked window surround with the Gran Coupe name embossed near the rear doors. All versions also get standard full-LED headlights. Inside, there's high-gloss black trim covering the center and LEDs illuminating portions of the interior. Beyond these minor alterations, BMW is offering two new options packs for the family that tweak the looks. While the company doesn't have any earth-shattering changes in store, they are there. Try to spot the changes in the refreshed 6 Series models as they sit on the floor of the 2015 Detroit Auto Show. The new BMW 6 Series: Three Body Styles Rejuvenated and Ready to Take on the Competition Woodcliff Lake, N.J. - December 10, 2014 6:00pm EST/3:00pm PST... Through three generations, the BMW 6 Series has defined that unique blend of style and elegance with the performance and handling that one would expect of The Ultimate Driving MachineTM. For the 2015 model year the third-generation of BMW 6 Series receives a range of enhancements that refine the character that is unique to the 6 Series. Now offered in three distinct body styles – traditional two-door Coupe, open-air Convertible and unique four-door Gran Coupe – all three are again offered with a choice of BMW TwinPower Turbo engines, the 315 horsepower inline-six in the 640i models and the 445 horsepower V8 in the 650i models. Sitting at the top of the 6 Series range, in terms power and performance, is the BMW M6 with its 560 horsepower M TwinPower Turbo V8, again available in all three body styles. The 2015 BMW 6 Series will make its world debut at the North American International Auto Show and arrives in US showrooms in the first quarter of 2015.
