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.)

Acura TLX Type S vs. BMW M340i xDrive | Sport sedan comparison test

Luxury sport sedans are still turning up on the market, and the Acura TLX Type S is one of the freshest cuts of meat in the window. It’s AcuraÂ’s big return to Type S performance models. Benchmarked against the proverbial best performance sedans of the segment, Acura is aiming to not just to compete, but to win dogfights like these. To see if the return of Type S is all itÂ’s cracked up to be, we decided to pin it up against the historical king of sport sedan shootouts: a BMW 3 Series. Specifically, the Type S is taking on the M340i xDrive, which is this AcuraÂ’s most natural competitor from Munich. Should the diehard BMW driver make the switch to Japanese performance? Does Type S do enough to lift this Acura up to best GermanyÂ’s finest? There are a lot of variables at play here, and they all make it complicated to choose a winner. The similarities between these two begin from the top of the spec sheet and go down. Both have 3.0-liter turbocharged six-cylinder engines — BMW arranges its cylinders inline, while Acura chooses a V configuration. Quick-shifting automatic transmissions are standard. BMW uses an eight-speed unit, while Acura uses a 10-speed. Both get electronically-controlled dampers, big brakes and sticky summer rubber. They each offer up usable backseat space and reasonably-sized trunks. WeÂ’d feel just as confident showing up to an important business meeting in either one as we would at a track day. ThatÂ’s the beauty of this mid-tier performance segment. After looking at their specs, it shouldn't be surprising that the M340i is the quicker of the two here. Its 382 horsepower and 368 pound-feet of torque hit noticeably harder from any speed than AcuraÂ’s 355 horses and 354 pound-feet of torque. The Acura is also carrying an extra 232 pounds of curb weight over the Bimmer, which makes the M340iÂ’s 1-second advantage in the 0-60 mph sprint make perfect sense. For the record, BMW quotes a 4.1-second time, and Acura only offers an approximate time of 5 seconds. Both estimates feel accurate. Beyond sheer acceleration, both engines offer up their own version of tingly feel-goods. BMWÂ’s inline-six is as smooth as ever as it plays its sonorous note all the way to the 7,000 rpm redline. There are few sounds in the automotive universe that surpass the glee we feel when listening to a BMW inline-six at full-chat, and that rule still applies to the M340i.

These are your top 10 worst-selling vehicles of 2012

Despite 2012 being the best year of auto sales this country has seen since 2007, not every vehicle got an equally large share of the sales pie. Some barely got a sliver, as evidenced by this year's list of the top 10 worst-selling vehicles of 2012. We've dug through sales data from every automaker to come up with this year's list and, like last year, we've set some parameters to ensure it includes legitimately bad-selling vehicles. The first parameter is a starting MSRP under $100,000, which automatically excludes what's parked in most one-percenters' garages. We're also excluding vehicles cancelled in 2012, even if they garnered sales through the end of the year while dealerships sold off remaining inventory. This includes models like the Mitsubishi Eclipse, Mercedes-Benz R-Class and last year's worst-seller, the Acura RL. Next, vehicles are considered as they are reported by the automaker, which means that, while sales of the Murano CrossCabriolet were probably low enough to make the list, because Nissan reports only one number for all Murano sales, it was excluded. Cadillac, however, reports sales of the Escalade EXT separately from the Escalade, hence its repeat appearance. Finally, there was the question of whether or not eligibility should be given to Suzuki vehicles, as the brand announced in November that it would end sales in the US as soon as its current inventory ran out. We decided Suzuki vehicles should be included as the brand was offering 2013 models at the time of the announcement, and as far as we can tell, inventory levels remained high enough to satisfy demand through the end of the year. Without further ado, below are the top 10 worst-selling vehicles of 2012. Top 10 Worst-Selling Vehicles of 2012 10. Volvo C30 MSRP: $25,500 Units Sold: 2,827 Last Year: – 9.
