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.

The Homer to contest 24 Hours of LeMons

It's finally happened. A 24 Hours of LeMons team has built the definitive interpretation of The Homer from The Simpsons for competition in an upcoming race. As you may recollect, The Homer is the fictional car designed by Homer Simpson for his brother's car company. Designed with a separate compartment for screaming children and other Homer-centric goodies, the animated machine bankrupted its parent company and put Homer's brother out of a job. Now we get to watch it race other crap cans as it tackles Southern California's Buttonwillow Raceway on June 29. Scott Chamberlain, Kris Linquist, Reid Conti, Ben Reilly and Mike Yepes will helm the machine, and Jeff Herman serves as the team's creative director.
The racer is the latest incarnation of a well-abused BMW 3 Series. The team campaigned the same E30 under the "Prickstine" banner as a Chrysler Imperial tribute and "Porcubimmer," the latter being a riff on the ever-popular joke about the difference between porcupines and BMW models. Never gets old. You can check out a video of the finished Homer below, and be sure to like the team on Facebook to see updates from the race. Now, about that Canyonero...

BMW M4 sheds some camouflage for latest test run

Last time we saw the upcoming BMW M4 out testing, it was heavily clad with camouflage and decidedly homely looking (as most early development mules are). But in this latest set of photos, the M3 coupe successor has started to come into its own skin, and we're seeing a shape more closely akin to that of a rendering we brought you a few months back.
Unsurprisingly, the M4 coupe looks very similar to the 4 Series Concept that BMW debuted at the Detroit Auto Show earlier this year. And while non-M version of the 4er will likely look a bit more sedate, these spy shots clearly show an aggressive front fascia, large wheels and the usual quad-exhaust rounding out the rear end.
Naturally, the M3 sedan will launch before this M4 coupe (and convertible), and powertrain details are still unclear as of this writing. We understand that the current M3's naturally aspirated V8 will be axed in favor of some sort of turbocharged six-cylinder engine, and we've heard plenty of rumors as to what, exactly, it might be, but we have yet to hear any official confirmation.
