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 to unveil X4 in March

It's been about half a year since BMW unveiled the X4 concept in Shanghai. But if you've been waiting for news on when it will reach production, the latest intel indicates it'll be announced next March.
Just when in March? That's the strange part. Inautonews reports having been told by BMW that the new X4 will be announced on March 14. So, the Geneva Motor Show, then? Not quite: although that show will still be going on then, the doors open to journalists like us on March 4, not 14. So either someone has got some details mixed up, or BMW - for some reason - is planning on waiting until after Geneva to reveal the production X4.
Whenever it does, we'll be looking at a slantback version of the X3, much like BMW did with the X5 and X6, giving Bavaria a rival to the Range Rover Evoque and Porsche Macan.

BMW i8 headed to Frankfurt

According to Edmunds, BMW will reveal its production i8 hybrid sports car at the Frankfurt Motor Show next month. The i8 is the second vehicle to come from the automaker's new "i" initiative, following the debut of the smaller i3 hatchback last month.
The BMW i8 makes its debut nearly four years after the original Vision EfficientDynamics concept bowed at the Frankfurt expo in 2009. The production car is expected to use a 1.5-liter three-cylinder engine that drives the rear wheels, coupled to an electric motor that drives the front wheels. Combined output is said to be something like 393 horsepower and 406 pound-feet of torque, based on our earlier reports. The i8 is also expected to be very light, with curb weight coming in somewhere around 3,125 pounds. Finally, the i8 is said to have a pure electric range of 20 miles, and should be able to hit 62 miles per hour in just under five seconds.
Other publications had the chance to ride along in the i8 (in prototype form) and came away impressed. We're hoping we'll feel the same when the car officially goes on sale sometime in early 2014. Stay tuned for more at the i8's official unveiling in just a few weeks.
