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 3 Series Gran Turismo gets leaked well ahead of Geneva reveal

The great power of the internet has allowed us to get an early first look at the all-new BMW 3 Series Gran Turismo, a car that is slated to be shown in full at the Geneva Motor Show next month, albeit without many details to go on right now. With pictures leaking out this early in the game, we'd expect that you won't have to wait until March to get the full lowdown, however.
Our first look at the 3er GT reveals a car that is, to our eyes, a tidier piece of design work than its 5 Series GT brother. The long-backside proportions are still a bit ungainly, at least from these images, but they're helped tremendously with the larger wheel/tire package and more aggressive fascia of the sport package.
Expect the 3 Series GT to hit the ground running, with the same turbocharged 2.0-liter four-cylinder and 3.0-liter inline-six found in the standard 3 Series sedan. BMW's popular xDrive all-wheel-drive system is a virtual lock for the option sheet, too.

BMW revises X1 to tide it over until replacement

It's been over five years since BMW first introduced the X1 at the 2008 Paris Motor Show, and a bit over a year since it brought the compact crossover to these shores. Soon the Bavarian automaker will replace the X1 with a new model based on the company's new front-drive architecture, but not before it gives it a few updates to keep it fresh.
Set to be unveiled at the Detroit Auto Show next month alongside the Z4 Pure Fusion Design and the new M3 sedan and M4 coupe, the enhanced X1 benefits from some new exterior accents, a spruced-up interior and new technology packed inside.
New air intakes in the bumper and integrated daytime driving lights distinguish the front end, with new wheel and color options available. Inside, certain versions get a new dashboard treatment, among other minor trim updates, and BMW has installed its latest ConnectedDrive suite to keep it up with the times.
