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.

Monsoon rains disrupt production for Ford, BMW in India

Even modern production techniques can be stymied by Mother Nature. This was demonstrated most recently in India, as torrential, monsoon rains caused a deluge that forced multiple automakers to suspend production. Ford, Renault, and BMW all halted work at their Indian facilities around the southern city of Chennai, also known as Madras. The annual rains disrupted public transport around the city, preventing employees from making the trek into city's factories. According to Automotive News, Chennai saw 48 inches of precipitation last month alone, which is more than Seattle, WA saw in all of 2014. While Ford and BMW closed things down for all of December 1, Renault just cancelled a pair of shifts at its Chennai factory. This is the second time in the past month that automakers in southeast India have been forced to stop production due to severe flooding, and things aren't likely to improve. According to The Weather Channel, forecasts call for thunderstorms over five of the next seven days, while the chance of rain won't fall below 80 percent until December 8. Ford, Renault, and BMW are far from the only automakers that could stand to be impacted by the rains. The city has been nicknamed "The Detroit of India" for its extreme automotive presence. Daimler, Hindustan, Hyundai, Mitsubishi, and Nissan all own factories in the region.

BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
"What we'd like is more focus on lightweight engineering." -Matt Collins
