Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)

BMW X3 spied with nip and tuck nearly complete

With the style-driven BMW X4 coming along in development, it looks like some of the forthcoming crossover's design could trickle over to its utilitarian sibling, the X3. Captured in these spy shots, it appears that the 2015 BMW X3 is preparing for a minor facelift, and from what we can tell, the biggest change will center on the CUV's headlights.
There is plenty of camouflage on the front and rear fascias to suggest updates will occur there, too, but we can definitely tell that the X3 will be getting LED-equipped headlights - at least as an option, anyway. The halos are slightly different from the current offering and there is also an LED strip above the headlights used as turn signal indicators. Another interesting thing we notice in these pictures is the nub at the bottom of the grille (also visible in recent X4 spy shots). While this could be some sort of test sensor for this prototype, it could also be a front-mounted camera for a possible parking assist system.
We don't expect any changes to the powertrain and we're not sure what updates could be in store for the interior, but we're guessing that that the 2015 X3 will debut shortly after the X4 goes on sale next year.

What does the open patents deal mean for Tesla ... and BMW?

Gift to the world or trade bait? Tesla Motors announced this week it would open its patents for other automakers to use. That has analysts guessing whether the California-based electric-vehicle maker is looking to either swap trade secrets with other automakers or to expand the proverbial pie that represents the plug-in vehicle market. For its part, Tesla says the answer is B. BMW, which is establishing its i sub-brand of plug-in vehicles, would be a natural collaborator with Tesla, Forbes says. In fact, executives from the two companies met in Europe this week. Details were not released, but a BMW spokesman said, "Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level." While Tesla brings battery technology to the table, BMW offers its carbon-fiber advancements that lighten vehicle-body weight. Those advancements are key to range-extending efforts and could do wonders for Tesla on its journey to help spur technology for the sake of getting more of the general public to accept plug-in technology as a viable first-car option. Then again, Forbes says Tesla, whose investors include Mercedes-Benz parent Daimler and Toyota, may be keeping its best technologies to itself by not patenting certain advancements at all. What's in Tesla's patent pool? uAutoInsurance analyzed Tesla's 249 patents and found that 104 of them related to battery technology, while 28 pertained to recharging activity, which wasn't surprising (about a quarter of those 249 patents couldn't readily be categorized). Tesla also has nine patents related to sunroof technology. The company is based in California, after all.
