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.

Check out 90 years of BMW Motorrad in 90 seconds

After ninety years in business and first-to-market motorcycle innovations like the one-piece 'tunnel' crankcase, hydraulically dampened front forks and full fairings, as well as that trademark boxer engine, BMW Motorrad is celebrating its nonagenarian status with a video: You can follow the ride on BMW motorcycles from 1923 to now in just 90 seconds.
Okay, so there's more than a video - some anniversary-themed bikes and a new retro boxer model celebrating the R 32 "airhead' from 1923 also commemorate the occasion. But you can start with the video, and that's below.

BMW M2 to pack 365 hp

The BMW M2 was spied testing several times last summer, but there has been little news about the upcoming entry to the M family as of late. More info is finally leaking out though, and it potentially confirms some past reports, while giving a better idea of what the coupe looks like. We have to take any of these leaks with a grain of salt, but according to a user on the 2addicts forum citing insider sources at BMW headquarters, M2 production begins in November. This person also reiterates that the coupe uses BMW's N55 turbocharged 3.0-liter inline-six. In this tune, it would reportedly make 365 horsepower and 343 pound-feet of torque. Plus, an over-boost system would allegedly push twist by about 25 lb-ft at low revs. At launch, this rumor also suggests that BMW might keep the M2's color palette limited to just four choices: Alpine White, Black Sapphire Metallic, Long Beach Blue Metallic and Mineral Grey Metallic. Inside, there're purportedly even fewer hues with the only one being black with blue stitching. Assuming these numbers are accurate, the M2 seems to represent a decent upgrade over the already capable M235i. It also uses a version of the N55 but a version making 320 hp and 330 lb-ft. In addition to the extra grunt, previous spy shots show the M with a front fascia akin to the M3/M4.
