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.

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.

Pininfarina Battista hypercar's output specified at 1,873 horsepower

Even in a galaxy far, far away, the Pininfarina Battista would stand out. After a delay of about three years, the official specifications of the all-electric hypercar have been revealed: Full power is rated at 1,873 horsepower, outputting 1,697 foot-pounds of torque. Sixty-two miles per hour arrives in 1.86 seconds, with 124 mph coming in 4.75 seconds. 217 mph is the estimated top speed. (The Rimac Nevera recently hit 258.) The 120kWh battery pack should enable a range of about 280 miles from a single charge. A pair of electric motors are mounted to each axle, each motor powering a specific wheel and giving the Battista full torque vectoring capability. Pricing — and this is one of those cars that, if one has to ask, just move on — is about $2.2 million, which places it in the territory of the Bugatti Chiron. For those customers considering an upsell, a limited “anniversario” edition will comprise five of the expected 150-unit build run. It differs from the standard version by some cosmetic alterations, which lifts the price by some $70,000-plus. 0r you could buy a BMW M3 as a chase car. The two-seater Battista is named for Battista “Pinin” Farina, who founded Carrozzeria Pininfarina in 1930. A lot of its battery, carbon-fiber chassis and motor components come from Rimac, the nascent Croatian electric supercar maker that recently paired with Porsche to take over Bugatti.  Many more details about the carÂ’s development, several photos and our driving impressions can be found in this Autoblog post from August.   Auto News By the Numbers Green BMW Bugatti Green Automakers Green Driving Coupe Performance Supercars Pininfarina Battista
