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.)

2015 BMW X4 slides in on the diagonal starting at $45,625 in the US

If BMW has shown us anything, it's a knack for creating niches and expanding its product portfolio. Go back to the early '90s and it had essentially four models: the 3 Series, 5 Series, 6 Series and 7 Series. End of list. Since then, the Bavarian automaker has not only taken on Mini and Rolls-Royce, but has expanded its own range of models exponentially. You can chalk a big part of that up to crossovers, and another sizable chunk to giving existing models a different roofline and calling it something new. What we have here is a prime example of both.
Previewed in concept form the better part of a year ago at the Shanghai Motor Show, the slantback version of the X3 (and the baby brother to the X6) is now here in full production guise. Mechanically it's essentially the same as the new X3 on which it's based, but amps up the "sport" at the expense of the "utility" part of the SUV equation.
BMW will undoubtedly offer a wide range of powertrain configurations in markets around the world, but back in the United States it'll be offered in two specs: the X4 xDrive28i, packing a 2.0-liter inline-four with 240 horsepower and a $45,625 sticker price (including destination), or the X4 xDrive35i with the 300hp 3.0-liter six and a $48,925 MSRP. Either way, you're getting an eight-speed automatic and all-wheel drive.

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.
