Behind the scenes of BMW's 'Driftmob' [w/videos]

All this, for one minute and 47 seconds of action-packed footage with no official plot.
We arrive in Cape Town, South Africa, on the third and final practice day for the drivers of a BMWStories internet video called The Epic Driftmob feat. BMW M235i. We are immediately whisked to a large, empty parking lot on the outskirts of Cape Town, where tires are squealing and chunks of rubber are flying as five red BMW M235i coupes churn up more smoke than a California wildfire. And the smell - it smells like heated metal, the kind of thing rev limiters are made for. Times five.

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's plans for next plug-in i model, due after 2020

BMW entered the fight in the green car ring with gusto thanks to the one-two punch of the i3 and the i8. However, it seems that there could be a wait ahead before the German's i sub-brand is ready to land another strike at the market. "We are still in the strategic research phase where we brainstorm," Klaus Frohlich, BMW Group development boss, said to Automotive News Europe about the future vehicle. He indicated the next new model to bear the i prefix wouldn't arrive until after 2020. Frohlich also underscored that the sub-brand's products wouldn't be based on a standard BMW product. The German brand was at one point rumored to have a model called either the i5 or i7 on the way that would have added a plug-in hybrid drivetrain to the 5 Series. Frohlich's statement would seem to invalidate that possibility. Although, there's nothing stopping the vehicle from carrying regular BMW branding in the vein of the X5 xDrive40e PHEV. The current i-badged models won't just stagnate on the market in the meantime, though. "We have a minimum 20 percent battery density improvement every three years, thus over the i3 and i8's life cycle, we will offer more performance, more range or a combination of the two," Frohlich said to Automotive News Europe. Sadly, current owners won't be able to upgrade to the improved parts, though. Rumors about a third i sub-brand model go back years with much of the talk swirling around the i5. In addition to the speculation about a 5-Series-based version, there was also supposed to be a stretched variant of the i3 with that name, possibly even with a hydrogen fuel cell version. Although, BMW claimed the vehicle was purely "hypothetical." Related Video:
