BMW Concept Roadster has two fewer wheels than we were expecting

The annual Concorso d'Eleganza Villa d'Este on the shores of Lake Como is an opportunity for some of the most beautiful vehicles in the world to descend on one of the poshest places on earth each year. Unsurprisingly, the event is also increasingly the chance for automakers to debut exclusive concepts to some of the wealthiest auto enthusiasts in the world. In the last few years, BMW has become the masters of this annual unveiling with automotive concepts like the Gran Lusso Coupé, BMW Zagato Coupe and motorcycles like the the gorgeous Concept 90, not to mention the just-revealed Mini Superleggera Vision. But this year the Bavarian automaker has been somewhat tricky.
What would you first think when you heard of the BMW Concept Roadster? A lithe, two-seat convertible? Nope. This roadster is a cut-down, minimalist motorcycle with an ultra-modern design. As opposed to the retro looks of the Concept 90, this naked bike looks like it could fit in a BMW showroom tomorrow and not seem out of place.
The Concept Roadster packs the brand's classic two-cylinder boxer engine displacing 1,170 cubic centimeters and producing 123 horsepower and 92 pound-feet of torque. That power is routed to the rear wheel via a cardan drive, essentially a driveshaft, with a single-sided swing arm rear suspension. It's all nestled in a tubular spaceframe.

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 reveals new X5 Security Plus in Moscow

A major player in the Russian market, BMW is heading to the Moscow Motor Show this month with a slew of local debuts... most of which we've already seen. But among all the new models making the trek from Bavaria to Moscow will be the new X5 Security Plus.
In a new-model launch that will surprise exactly no one, BMW's latest armored vehicle upgrades the X5 with enhanced protection for oligarchs against Chechen rebels, AK47-touting gangsters and missiles randomly falling on Crimean highways. Now meeting the VR6 standard of ballistic protection, the new X5 Security Plus incorporates reinforced bodywork, seats and joints, along with bulletproof glass.
Of course all that reinforcement (not to mention the jars of beluga caviar and bottles of Stoli in the glovebox) will come with a weight penalty, but the 4.4-liter twin-turbo V8 ought to do the trick, driving 450 horsepower through BMW's xDrive all-wheel-drive system to get the vehicle's occupants out of a war zone in a hurry.
