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 M4 Concept leaked ahead of Monterey debut

Last month, we heard that BMW might be bringing a concept previewing its next M4 sports coupe to this year's Monterey festivities. Well, thanks to the folks at USA Today, we have absolute confirmation of this by way of some leaked images. And goodness, she's certainly a looker.
While a few of us still find some of the 4 Series' design to be a bit awkward, it's hard to not immediately warm up to the aggressive bits of this hotter M4 concept. It certainly looks the business of a proper sports car, and a worthy successor to the M3 coupe. Of course, a lot of this will likely be toned down for the production version, which we'll likely be seeing at the 2014 Detroit Auto Show in January, along with its four-door M3 kin.
The official M4 Concept details will be revealed later tonight, but for now, have a look at a few shots of the golden show car in our gallery of leaked shots, above.

Audi leading rival BMW in worldwide luxury sales race

If you thought competition among the German luxury automakers was hot before, it looks like things are just getting started. For the first two months of the year, Audi has sold more cars than BMW worldwide by just 383 cars.
Audi claims to have sold 242,400 vehicles through February, up 9.3 percent from last year, compared to 242,017 units from BMW, up 8.9 percent, in the same period. While the advantage is tiny, its implications could be huge because Bimmer has been the leader in the premium car segment for the last nine consecutive years. Mercedes-Benz lags behind them somewhat at 229,630 vehicles through February. According to Bloomberg, at this time last year Audi had sold 429 fewer cars than BMW.
The growth is all part of Volkswagen Group's goal to become the world's largest automaker. It currently ranks in second when its heavy truck businesses are considered. The German automotive giant also wants to be the world's leading premium carmaker. "Competition in the premium segment is more intense than ever," said Audi CEO Rupert Stadler to Bloomberg.
