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.

Recharge Wrap-up: Tesla Gigafactory gets high-tech neighbors, BMW i8 still comes with a long wait

Switch plans to build a large data center near the site of Tesla's Gigafactory battery production facility in Reno, Nevada. The 3 million square-foot facility in the Tahoe-Reno Industrial Center will cost $1 billion to build, and eBay is expected to be the main tenant when the first portion is finished in 2016. Apple is also building a data center nearby. One draw for companies like Switch, Apple and Tesla is access to the region's clean power, and the Reno area could become the next big center for high-tech manufacturing. Read more at GigaOm. Daniel Sparks of investing website The Motley Fool has shared his insights after living with the Tesla Model S for four months and 10,000 miles. After driving his 85-kW version through various conditions, including a 2,200-mile road trip, Sparks is optimistic about the car and the company behind it. From his experience, he says that charging is easier than most people believe, and that range anxiety isn't a problem. He calls Tesla's growing Supercharger network a "game changer," citing their quickness, availability and the fact that charging is free for life. He also says that most people seem to know very little about the car. Still, he calls Tesla stock "pricey" with the growth already priced into the shares. Read more at USA Today. The wait for a BMW i8 is about a year, despite efforts to ramp up production. BMW is reducing production of the i3 in order to increase the number of i8s by more than 50 percent for 2015, but the bigger batch won't become available in the US until October. Ludwig Willisch, CEO of BMW North America, says that he doesn't expect cheap gas to slow sales of the i3. He also denies rumors of an i9 positioned above the i8. The new 7 Series appears to be taking some cues from the i8, though, with carbon fiber, magnesium and aluminum construction, as well as improved connectivity. Read more at Automotive News.

2015 BMW X3 gets a new nose, diesel power

The second-generation BMW X3 launched in late 2010, and while it's never really wowed us, it's still a solid offering in a highly competitive class. In an effort to keep things fresh, BMW has given its X3 a nip/tuck for the 2015 model year, but perhaps the biggest news (for the US market, anyway) involves what's found underhood.
In addition to the 2.0-liter turbo-four and 3.0-liter turbo-six, BMW will now offer an X3 xDrive28d, fitted with - you guessed it - the 2.0-liter turbodiesel inline four-cylinder engine found in the 328d sedan. Output for this engine is rated at 180 horsepower and 280 pound-feet of torque, and BMW says this oil-burning mill will help the X3 reach 60 miles per hour in just under eight seconds. The automaker hasn't released any information about real or predicted fuel economy figures for the diesel X3, as yet.
What's more, BMW will once again offer a two-wheel-drive X3 in the States - the sDrive28i. Pricing for the refreshed 2013 X3 starts at $39,325, not including $925 for destination. Opting for that diesel will set you back $42,825. Scroll down for the official press release, and check out a new brace of shots live from the soft-roader's Geneva Motor Show debut.
