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 8 Series coming in 2020

As good as the BMW 7 Series may be – and trust us when we say it is very good indeed – it just can't compete with the marketplace juggernaut that is the Mercedes-Benz S-Class, at least not where global sales are concerned. And with sales come profits, especially at the six-digit price point many of these high-end luxury cars sell for. Put simply, Mercedes is cashing in on the S-Class, and BMW wants a bigger piece of that pie. It comes as little surprise, then, that Autocar reports BMW is currently considering two proposals for a new 8 Series that would slot just above its current 7 Series. One option is the currently-en-vogue four-door coupe. The other option is a more traditional two-door coupe, likely with a cabriolet option. The last time we heard such rumors, BMW was dismissing them back in 2013. Whichever way BMW decides to take its 8 Series plans, Autocar suggests that a concept vehicle ought to hit the show circuit in sometime in 2018, with a production model following in 2020. The car would be based on the underpinnings of the latest 7 Series, with a price considerably less than the Rolls-Royce Ghost (which also falls under the BMW umbrella). Considering BMW's penchant for multiple model variants, we won't be surprised if all three options get the green light, with a Gran Coupe version standing as the flagship. With the 6 Series Gran Coupe currently priced just below the 7 Series (and at a hefty premium to a comparable 5 Series four-door), an 8 Series would likely brush up against $100,000 for a base price. That might not take much out of S-Class sales, but it would make some tidy profits for BMW. Related Video:

BMW recalling 1 Series ActiveE over bad drivetrain housing

There are always growing pains when automakers introduce new technologies. BMW is learning this with the electric powetrain used on the 2011 BMW ActiveE. According to the National Highway Traffic Safety Administration, about half of the all-electric 1 Series coupes currently in the hands of the public are being recalled for a potential problem that could leave the cars stranded.
With 700 ActiveE models running around the US, 360 of these cars have insufficient sealing between the electric motor and transmission, which could lead to premature wear to the connection between the two, which in turn could result in a loss of propulsion. BMW started notifying affected owners by phone earlier this month.
While no automaker wants a recall on its hands, it's much better for BMW to learn such a lesson now on the low-production, lease-only ActiveE ahead of the car's successor, the BMW i3, which is expected to be a much higher-volume EV. Scroll down for the official recall notification.
