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 Alpina B6 Gran Coupe challenges the M6 in New York

Despite being a well-respected outfit for decades, Alpina remains something of a mystery to many stateside BMW fans. In Europe, Alpina has established itself as a first-rate source for breathed-upon high-performance Bimmers, and it's looking to continue picking up traction on our shores. The US has received a handful of Alpina models through BMW factory channels, namely the 7-Series-based B7, and now we're getting another fast four-door with the debut of the BMW Alpina B6 xDrive Gran Coupe at today's 2014 New York Auto Show.
The B6 Gran Coupe stands as an interesting sibling to the factory's M6 Grand Coupe. Both are propelled by a 4.4-liter twin-turbo V8, but the tunes are quite different. The Alpina produces 540 horsepower and 540 pound-feet of torque, which is 20 hp less than the M6, but with 40 lb-ft more torque. An eight-speed automatic and all-wheel drive mean that the B6 is about half a second quicker to 60 miles per hour than BMW's own creation. Plus, the B6 has an unrestricted top speed of 198 mph, making it one seriously rapid 6 Series Gran Coupe.
The sport sedan also wears other Alpina goodies like 20-inch versions of the brand's 21-spoke wheels and exclusive color options. The B6 Gran Coupe goes for $118,225 (including destination), and will be available through BMW dealers immediately after the auto show ends. More info about the B6 is in the release below.

BMW brings burlesque, Warhol, M1 and 6 Series Grand Coupe to Paris Photo LA

BMW has worked with Paris Photo for ten years. This year, the photography exposition lands in Paramount Studios in Los Angeles for the first time, and BMW is not only coming with it, the Bavarians are bringing the Art Car that started it all: the 1979 M1 painted by Andy Warhol. For those attending the show, there will also be making-of video of Warhol working on the car - but if you remember the mini lecture that EVO magazine's Henry Catchpole gave on the Art Cars, you'll remember that Warhol finished the car so quickly that the cameraman barely had time to get the film rolling.
With that will also be a series of photos of the BMW 6 Series Gran Coupe dropped into noir scenes accompanied by burlesque models, all taken by photographer Uwe Düttmann. It's the first time they'll be exhibited at Paris Photo. You can check out a few of them in the high-res gallery above, and there's a press release below with more info.
