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.

Alex Zanardi talks new challenge at 24 Hours of Spa with BMW

"I have overcome greater things in my life than driving at night." When considering Alex Zanardi's tumultuous life and racing career, the notion that he might be worried about racing for the first time at night seems patently absurd the moment I pose the question. But as I've discovered previously, ask Zanardi a question and his reply - even a brief one - will offer analysis. "I'm really looking forward to it," he says, before adding: "Also, it will be much cooler." Zanardi is talking about the latest installment in his racing career - the 24 Hours of Spa - where he will race a BMW Z4 GT3 alongside fellow ex-Formula 1 driver Timo Glock and DTM driver Bruno Spengler. For the second year, Zanardi is running with ROAL Motorsport, and the team has the full weight of BMW behind it as it prepares to go up against 57 other cars on the historic Belgian circuit this weekend. I first met Zanardi last year at Brands Hatch on a hot May afternoon after his one-hour Blancpain Sprint Series race. He was exhausted and downing can after can of cola but still happy to chat to fans as he cooled off. I ask why, if that was such a tough experience, he is prepared to do it for 24 hours. "It's a good question, why would I?" he ponders aloud before quickly adding: "I am confident I am as well-equipped as I can be to face such an enormous commitment." That confidence comes from three developments that have allowed him to be the first disabled driver to race the Spa 24H. Firstly, his athleticism; since Zanardi lost both his legs in the horrific CART accident at the Lausitzring in 2001, he has drawn admiration for his subsequent achievements as a racing driver and paracyclist; the Italian won two golds and a silver at the 2012 London Paralympics in handcycling. The man is seriously fit. The next major change is inside the Z4 cockpit, where he has worked with BMW engineers to adapt the braking system without hindering his able-bodied teammates; having two others sharing the car with him is a new challenge for both Zanardi and BMW. New controls, particularly the brake pedal, were designed with impressive results. "[The engineers] made my life easier quite dramatically via ergonomics, pushing the brake pedal and the footrest where I put my prosthetic feet to the side of the space that was available. "This makes everything better for me. The ratio of the brake pedal is changed.
