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 02 Series mini-documentary makes us fall in love all over again

BMW's current reputation of building Ultimate Driving Machines can be traced back through history all the way to 1966, when the German automaker introduced the world to its 1600-2 two-door at the Geneva Motor Show. The car's name was simplified in 1971 to BMW 1602, and it went on to spawn the 2002, one of the most famous BMW models of all time.
BMW looks back on its past successes in a video that you can see below. As the automaker itself says in the video description, "This series was extraordinarily successful in reinterpreting the concept of the sports saloon and played a major role in motor sport long after production had come to an end." The 2002 would be replaced in 1975 by another legendary model from BMW: the 3 Series.
We'd be lying if we said we didn't long for something along the lines of the classic 2002 from BMW today. Since that doesn't seem likely to happen anytime soon, join us in remembering the cars that helped make BMW a household name by scrolling down below.

Xcar checks if BMW's i8 offers moves as electrifying as its looks

If you were to plot the general opinion about hybrids since their introduction among auto enthusiasts, the resulting graph would likely be shaped somewhat like a "V." In the beginning interest was high, simply due the novelty of these new powertrains, then the line would gradually fall as the models got the stereotype of being boring commuters. Today, though, things might be back on the upswing. Vehicles like the McLaren P1, Porsche 918 and BMW i8 are showing that a hybrid doesn't have to be synonymous for dull. In its latest video, Xcar Films aims to find out if BMW's electrified sports coupe actually earns the brand's old moniker as the ultimate driving machine.
While the focus here is on what the i8 is like behind the wheel, one of the main highlights for the viewer is the interesting ways that Xcar shoots the BMW. It's not necessarily a beautiful vehicle, but seeing it in motion reveals all sorts of little intricacies that still photos don't pick up. For example, our eye catches the flying buttresses and little crevices scooped out of the corners when we get a look at the rear. It's just a fun car to look at.
With its 1.5-liter, turbocharged, three-cylinder engine and electric motor, the i8 positions itself as the future of automotive performance. But its intriguing looks and cutting-edge use of carbon fiber would be wasted if the coupe didn't drive well. We won't spoil the final verdict, though, you'll have to watch the video above.
