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 Individual gives 760Li a Sterling reputation

Standard chrome too plebeian for your taste? You can order a Rolls-Royce with its Spirit of Ecstasy hood ornament made out of just about anything you want: gold, silver, glass... you name it. But if your sense of style is a bit less Anglo and a bit more Saxon, BMW has another option for you.
Feast your eyes on the BMW Individual 760Li Sterling edition. (But don't look directly at it. Don't you dare.) Crafted in partnership between BMW Individual and the silversmiths at Robbe & Berking, the special 7 Series is adorned with hammered sterling silver trim inside and out. The twin-kidney grille, the emblems, the interior trim panels... all hand-made in silver. So you won't want to park this particular Bimmer in the wrong neighborhood, because unlike the Rolls ornament, these don't retract safely under the hood.
The special edition gets a dark grey exterior tint and brown leather interior, the best to highlight the silver brightwork. Otherwise it's mechanically identical to any other 760Li (or so we would presume, as the press release didn't mention specifically), that being the flagship version of BMW's flagship sedan, complete with 6.0-liter twin-turbo V12 at the front end of a long wheelbase. Check it out in the gallery above, including the build process at both BMW Individual and Robbe & Berking, and press release below.

BMW 2 Series Active Tourer pulls its way onto the stage

We know what you might be thinking: here comes another BMW with yet another kind of roofline. Only this isn't just another BMW. It's the first front-drive BMW, and the first time we've ever seen it in person.
That model, of course, is the new 2 Series Active Tourer, debuting here in Geneva as the production version of the Concept Active Tourer and the beefier Concept Active Tourer Outdoor that followed. It shares about as much with the 2 Series Coupe as a jelly donut, but takes BMW into a new market segment - that of the high-roofed hatchback (or micro-minivan, depending on your perspective) occupied by the likes of the Mercedes-Benz B-Class and Volkswagen Golf Sportsvan.
Power comes from a choice of 1.5-liter turbo three, 2.0-liter turbo four or 2.0-liter turbodiesel - but aside from the forced-induction engines what they all the versions have in common is what makes the 2 Series Active Tourer newsworthy: they all sit up front, driving the front wheels. It's an idea BMW purists might not appreciate, but one we'd all better get used to just the same.
