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 mulled ten, eight, and six-cylinder engines for i8 before going hybrid

There's little doubt that the 2015 BMW i8 is one of the most radical and groundbreaking performance cars this industry has seen in a long time. From its unique carbon-intensive construction to its 1.5-liter, three-cylinder and electric motor plug-in powertrain to its concept-car appearance, the flagbearer for BMW's new i venture challenges the very notion of what it takes to be a supercar.
Yet apparently the i8 almost didn't do that at all. Yes, it probably still would've had innovative assembly techniques, serious performance and come-hither bodywork, but according to a new report in the Telegraaf, it was very nearly a much more conventional beast, drawing its power from a V10 engine. According to the report, that line of development never got much beyond the drawing board, but BMW engineers then shifted their focus to both V8 and six-cylinder motivation, going so far as to build prototype cars. The higher cylinder-count engines were eventually dropped altogether after BMW decided to turn the i8 into a hybrid, with the six-cylinder reportedly nixed due to heat management and weight issues. In the end, of course, BMW went with the PHEV powertrain that offers a total system output of 362 horsepower and 420 pound-feet of torque - plenty of thrust for this lightweight, all-wheel drive coupe while still enabling an incredible 94 miles to the gallon on the EU cycle. Regardless of how it turned out, it's still fascinating to think that BMW didn't have a much firmer conceptual idea of what it was after when it started the i8's development.
Here at Autoblog, we're genuinely thrilled about this new generation of greener hybrid super- and hypercars, a movement spearheaded by the i8, Porsche 918 Spyder, Ferrari LaFerrari and McLaren P1. But even so, our inner-gearheads can't help but wonder what might have been had BMW pursued a more conventional i8, either in place of, or in addition to, the car they did build. What do you think?

Recharge Wrap-up: Derailing Malaysia's B10 plans, Tesla and Solyndra

Tesla Motors will lease the Solyndra building near its Fremont, California factory. The manufacturing facility is more than 500,000 square feet, but the cost of the lease and the production capacity remain undisclosed. The lease of the building, "located conveniently down the road from the Tesla Factory, gives us the space to expand our manufacturing and build more engineering labs as we build up production," says a Tesla spokesperson. The added manufacturing space will help Tesla meet its production goals for the upcoming Model X electric SUV. Trip Chowdhry, senior analyst at Global Research Equities, says that shifting some engineering duties from the Deer Creek facility to the new one could help solve current parking shortages, as well.

Malaysia recently announced that it would use crude palm oil to make the B10 blend that would be required to be sold beginning in October, up from the current B7 mandate. "In our tests with B10 biodiesel worldwide, we have found technical challenges," says BMW Group Malaysia Managing Director and CEO Alan Harris, such as the fatty acid methyl ester in palm oil thinning motor oil. Mercedes-Benz also urges reconsideration of B10. The Malaysia Automotive Institute says it will include representatives from the auto industry in talks with the Malaysian Palm Oil Board.

In 2009, ethanol suffered a price drop that forced Pacific Ethanol to decrease production and declare bankruptcy for four of its plants. Now its base extends from the West Coast to the Midwest, as Aventine Energy Holdings has four plants in Illinois and Nebraska. The merger more than doubles Pacific Ethanol's production capacity, making it the fifth-largest ethanol producer in the US. Read more from The Sacramento Bee.
