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 i8 will be first production car to use Gorilla Glass

What do smartphones and the BMW i8 have in common? Glass. Scratch-resistant Gorilla Glass, that is. The i8 will be the first production car to use the chemically hardened material, which is more durable, lighter and provides more sound deadening than conventional laminated automotive glass. We thought it would be a natural replacement for windshields, but, according to Autoweek, BMW said it will be used for the rear window for sound deadening purposes. The Gorilla Glass will still be laminated, with two 0.7mm thick layers of it sandwiching an acoustic sheet, reports Autoevolution.
BMW reportedly claims the i8 will weigh less than 3,285 pounds, and to offset the heavy hybrid powertrain to reach that goal the automaker has implemented lightweight materials normally not found in mass-production automobiles. With a carbon fiber reinforced plastic (CFRP) monocoque used for both the (relatively) pedestrian i3 and the upscale i8, it's not surprising BMW was also the first to jump onto Gorilla Glass, especially given the timing of a report that a high-end automaker would introduce it within the year.
Be sure to check out our First Drive review of the i8 to see if BMW's newest sports car is living up to the hype.

Auto execs surveyed say VW, BMW most likely to grow

A new survey of top global automotive executives indicates both Volkswagen and BMW are the most likely to grow their market share over the next five years.
Tax advisory firm KPMG LLP has released its 14th annual Global Automotive Executive Survey, which includes responses from over 200 executives. A total of 81 percent of respondents said they expect to see Volkswagen make gains, compared to 70 percent last year. BMW, meanwhile, saw 70 percent of those surveyed say they believe the company will increase its market share. That's a jump of 7 percentage points over last year. This is the first time in the history of the survey that BMW has claimed the second-place spot.
Meanwhile, Hyundai has seen its perceived market share potential slacken for the third year in a row. Around 61 percent of those surveyed predicted gains for Hyundai, down from 63 in 2012. Toyota also has a surprising year, but for just the opposite reason. While the manufacturer had slipped in ranking since 2011, it enjoyed the largest increase of any company in the 2013 survey, jumping to 68 percent from 44 percent last year.
