Check out the trick way you access the tire valve on this BMW Alpina B6

The wheels are one of the first things you notice when checking out the 2015 BMW Alpina B6 xDrive Gran Coupe. The 20-inch aluminum alloy rollers have 21 spokes that spray out from their hubs, creating one of Alpina's signature design features. But there's also plenty of function to go along with the stylistic form of this hotted-up BMW 6 Series Gran Coupe.
By rotating the Alpina roundel and unlocking the center hub, you gain access to the tire valve and bolts, which are hidden inside. They're literally kept under lock and key, and they protect your Alpina's wheels from the elements and theft. This unique center-fill system employing a hollow spoke isn't a new setup for the favored BMW tuner, but since Autoblog had one in our offices this week, we thought we'd take the opportunity to show the unique mechanism in case you haven't seen it before. Check it out in our brief video below.

BMW makes X7 in Spartanburg official

BMW has made it official - there will be a flagship crossover called X7, and it will be built right here in the US of A. The announcement was made today, confirming rumors of the new model at the Spartanburg, SC factory that broke earlier this week.
"Plant Spartanburg was built to enhance and expand the BMW lineup, underscoring the BMW Group commitment to the United States" said Dr. Norbert Reithofer, chairman of the BMW board of management in a statement. "In addition to the X3, X5, X6, and the new X4, we are today announcing another all-new, larger X model to be manufactured exclusively at this plant for our world markets: the X7."
BMW will spend $1 billion by 2016 upgrading its South Carolina factory, which already produces the X3, X5 and X6. The plant is currently capable of producing 300,000 units per year, but with the big investment from BMW, capacity will climb to 450,000 units. 800 jobs will be added as a result of the investment and new and upcoming models.
