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.

Recharge Wrap-up: BMW X5 PHEV debuting in Shanghai, Proterra sets up shop in CA

South Carolina-based Proterra has received funding to build electric buses in California. The California Energy Commission has awarded the company, which is headed by former Tesla executive Ryan Popple, a $3-million grant. Proterra will use the funds for a facility in the LA suburb the City of Industry, where its largest customer, Foothill Transit, also operates. Proterra has also opened an office in San Bruno, just south of San Francisco. Read more at SFGate or at ValueWalk. Despite its "urban mobility" design, the BMW i3 has become popular outside of large cities. Rather than singular urban centers, "The strongholds in this country are parts of California, Texas and southern Florida," said BMW North America CEO Ludwig Willisch. He also says the electric car hasn't been particularly successful in the Northeast, with cities like New York perhaps not being as mindful of sustainability as California. BMW is also nearing i3 sales of 12,000 a year, which Willisch calls "a sustainable rate." Read more at Automotive News. BMW will debut its X5 xDrive40e plug-in hybrid at the Shanghai Motor Show this month. It is the first PHEV from BMW's core brand (not from its i sub-brand). It uses a turbocharged four-cylinder engine and electric motor for a total of 313 horsepower, and a combined fuel economy of about 70 miles per gallon (according to the ECE test cycle). Press days for the Shanghai Motor Show are April 20-21. Read more in the press release below. BMW at Auto Shanghai 2015.
