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 Concept 90 Motorcycle debuts at Villa d'Este

The Concept 90 is one of two new vehicles BMW is showing off at the Concorso d'Eleganza Villa d'Este on the tony shores of Lake Como in Italy. This year is the 90th anniversary of BMW Motorrad and the 40th anniversary of the R 90 S (inset) - the first production motorcycle to come with a front fairing - and BMW has worked with custom bike builder Roland Sands Design to craft a homage to the Daytona Orange boxer from the Seventies.
While following the line of its forbearer, obviously the Concept 90 has been sexed and sleeked up. The bodywork is of hand-worked aluminum, the giant halogen lamp of the 1975 model (which is when Daytona Orange was introduced) has gone LED, and the front engine cover, valve covers, exhaust and wheels have been made with a contrast-cut milling process.
For a finer description of the Concept 90 check out the press release below, or skip the words and go straight to the high-res images above.

BMW calls in 50,000 motorbikes over fuel pump leak

If you don't often see motorbikes being recalled, it's probably because there's less to go wrong on a motorcycle. But a problem with the fuel pump on a wide array of BMW Motorrad products has prompted the National Highway Traffic Safety Administration to issue a recall for over 50,000 of the Bavarian two-wheelers across America.
The issue revolves around the fuel pump flange on R-model, K-model, S 1000 and HP2 motorcycles built as far back, in some cases, to 2005 and as recent as 2012, depending on the model. The flange was found to be prone to crack and leak fuel, which NHTSA evaluated as a fire risk. As a result, precisely 50,184 such motorbikes are being recalled to have their flanges reinforced or, where necessary, to replace the entire fuel pump. If you're the owner of such a Bimmer bike, expect a call from your dealer sometime next month, but you can read the full notice below.
