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.)

Audi investing $30.3 billion through 2018 for product expansion

How does Audi plan to reach two million units in annual sales and pay for the 11 new models it's adding to its lineup - an expansion that may include models named SQ2, Q9 and F-Tron? By increasing its investment to 22 billion euros ($30.3 billion US) between now and 2018. That figure represents an increase of about 500 million euros over the previously planned outlay, according to a report by Automotive News, and that could be due to Audi wishing to goad the momentum that pushed it to 1.5 million annual sales two years ahead of schedule.
It's also about staving off the challenges from BMW and Mercedes-Benz. Now that BMW has been able to turn some of its attention away from its "i" series of Megacity cars, it will reportedly spend more than planned in 2014 as it continues the rollout of ten all-new vehicles and 15 new-generation vehicles through the end of next year. Mercedes, having been dropped to third in the sales race, is preparing to add 13 new cars over the next six years.
Audi's money is going into technology, into product like the next-generation TT and the Q1 and production expansions and upgrades all over the world. The expenditure represents just under a fourth of Volkswagen's 84.2 billion-euro ($115.7 US) outlay devoted to taking the number-one global automaker title away from General Motors and Toyota by 2018.

BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.
