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 i3 owners in California get $1,000 to delay charging

It's fairly rare to get paid for doing absolutely nothing, but that's exactly the case for a select group of BMW i3 owners in California. A hundred people are part of the ChargeForward pilot program in coordination with BMW and Pacific Gas & Electric Company, and each participant gets a $1,000 gift card to not plug in their cars – at least not whenever they want to. It's all part of an attempt to develop strategies to reduce the strain on the grid during peak usage. The trial runs from July 2015 to December 2016 in California's Bay Area. According to the automaker's website, when plugged in, BMW has the ability to delay the charging of the i3s by up to an hour. There are no necessary mechanical or software modifications necessary, either. Although, if drivers desperately need the juice, they can also opt out of the program for a day. At the end of the experiment, the people are eligible for a second gift card for up to another $540, depending on their involvement. According to Bloomberg, with 65,000 electric vehicles in Northern California, the power company estimates the area has among the highest concentrations of EVs in the country. While all of those emissions-free miles are great for the environment, plugging them all in once just adds to the load on the system. As a second part of the program, used Mini E batteries are being repurposed to create a solar-powered, stationary storage system that Pacific Gas can also use to supplement the grid.

BMW launches new M Performance accessories for M5, M6

Those looking to make their stock BMW look like an M model might be interested in an M Sport package. But those who already drive an M model and want that extra bit of attitude to take it over the top look towards the M Performance Accessories catalog, to which BMW has just added a new range of add-ons for the M5 and M6.
The new range of accessories include a titanium exhaust from Akrapovic that's 22 pounds lighter and an extra bit throatier than the stock unit. BMW's also offering a carbon-ceramic brake kit and 20-inch alloys to accommodate them, as well as a carbon aero kit, carbon interior trim and those trademark stripes for the truly extroverted BMW performance enthusiast.
You can check them out in the gallery above and the press release below to see what Martin Tomzczk, the DTM driver sponsored by BMW M Performance Accessories, chose for his matte black M6 Gran Coupe daily driver.
