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 reveals Concept Compact Sedan in Guangzhou

While our eyes were fixed on Los Angeles, BMW turned its attention to Guangzhou, China, where the German automaker unveiled the Concept Compact Sedan. The show car envisions a Bavarian rival to the likes of the Mercedes-Benz CLA-Class and Audi A3 sedan. Munich released little in the way of technical details. Instead, the Concept Compact Sedan is all about the design. Relative to its form, the show car rides on a long wheelbase, with the wheels pushed to the corners, and a greenhouse set back behind a long hood. The details are distinctly Bimmer, from the signature double-kidney grille to the Hofmeister kink in the C-pillar. The horizontal lines of the front and rear fascias are designed to maximize the vehicle's visual width, and the muscular design integrates touch-sensitive door handles below the swage line for a cleaner look. All that is rendered in liquid metal bronze paint, offset by polished aluminum brightwork and 20-inch split-spoke alloys. Geared towards the "life of a generation of youth in China," the interior is designed around the driver, but also seeks to maximize rear-seat space despite the vehicle's compact footprint. The horizontal treatment continues inside to give the impression of space, with upscale materials like three-tone Nappa leather, open-pore wood, and brushed aluminum trim with orange accents and ambient lighting. All the auxiliary surfaces are controlled by touch panels on the steering wheel, center stack, center console, and door handles. There's a panoramic roof, a head-up display for the driver, and an 8.8-inch screen in the dashboard. The sum total is a compelling preview of what a four-door addition to the 1 Series and 2 Series could look like. And to our eyes, it looks like it would be just as home on American roads as it would be in China, Europe, or anywhere else for that matter. Check it out in the high-res image gallery above and the details in the press release below. BMW Concept Compact Sedan. Sporty, elegant, exclusive – the perfect statement-maker. 20.11.2015 Munich/Guangzhou. The BMW Group has chosen Auto Guangzhou 2015, one of the largest international motor shows in China, to present a very special new development to the global public: the company's vision of a four-door sedan for the compact segment. "The BMW Concept Compact Sedan reveals the potential we see in a compact sedan," says Adrian van Hooydonk, Senior Vice President BMW Group Design.

BMW discussing supercar collaboration with McLaren

BMW is reportedly considering a new halo supercar. But rather than go it alone, word has it that the Bavarian automaker is discussing a potential partnership with McLaren to make the idea a reality. This according to Britain's Car magazine, which suggests that negotiations are well underway. The proposal would see the BMW supercar based on the same architecture that will to underpin Woking's P16 project that's set to replace current 650S. Rather than use the 3.8-liter twin-turbo V8 that McLaren developed together with Ricardo, the Bimmer version would use Munich's own engine: a 4.0-liter V8 with quad turbochargers – two conventional spools and two more electrically driven chargers. Their combined effect would net an expected 750 horsepower. Further differentiations on McLaren's carbon monocoque architecture for use in the BMW would include custom bodywork, aerodynamics, and interior fitments to include a unique instrument panel. Production, however, would be handled at the McLaren Production Centre in Woking, to the tune of several hundred units per year. The project would take the place of several aborted programs undertaken internally at BMW. One called for an entirely unique supercar developed in-house, referred to internally as the M100. When that project was aborted so that BMW could concentrate on the i sub-brand, BMW's own skunkworks shifted its focus to developing a more performance-focused version of the i8, known by some as the i8 CSi. When that project was canned as well, discussions with McLaren commenced. It wouldn't be the first time BMW would outsource development of its own supercar, or even the first time BMW would collaborate with McLaren on such a project. Initial development work on the original M1 in the 1970s was undertaken by Lamborghini before being taken in-house. And, of course, BMW provided the engine for the legendary McLaren F1. Meanwhile McLaren performed a similar function for Mercedes-Benz with the SLR, demonstrating Woking's experience in building flagship supercars for German automakers. This latest project could suffer the same fate as the M100 and i8 CSi programs. But if it is approved, it could yield both coupe and convertible versions, with the first slated to surface at the Frankfurt Motor Show in 2017 and reach dealerships in 2019.
