Is BMW the only real competition to Tesla Motors?

Tesla Motors chief Elon Musk probably isn't losing a ton of sleep over the new plug-in efforts by the makers of the "Ultimate Driving Machine," but maybe he should. That's what the Motley Fool is saying, presenting the case that the California company's real competition will come from BMW. What about the plug-in efforts of General Motors or Ford? Musk can hit the snooze, Motley Fool says. Unlike automakers that are "jamming battery packs into the existing vehicle design," BMW has built its i3 battery-electric and i8 plug-in hybrid supercar from the ground up. Like Tesla, BMW puts its battery packs into the floor of its vehicles. Most importantly, the i3 - and especially the i8 - are real performers. While the i8 is about 40-percent more expensive than the Tesla, it matches the Model S's 0-60 mile per hour acceleration times and handily beats its top speed figures. Tesla sold about 6,900 vehicles during the last three months of 2013 and BMW had more than 10,000 i3 orders on the books by late November and the first year's allotment of i8s is already sold out. The German automaker has what the Fool calls an "outside chance" of selling more plug-in vehicles than Tesla by next year, but Tesla is gearing up its gigafactory to get ready to sell a half-million EVs in 2020, so the race is most certainly on.

BMW 7 Series could get M variant alongside Alpina B7

BMW is launching the new 7 Series with a limited engine lineup, but according to Car and Driver, there are more powerful versions on the way – including a potential M Performance model. The new 7 Series is initially being offered with a 320-horsepower turbo six and a 445-hp twin-turbo V8. European customers will also be able to spec a 261-hp diesel or a 320-hp hybrid. There's an M Sport package available as well with enhanced visual cues, but that won't be the extent of the performance choices when all is said and done. Expect a new 760i that will pack BMW's twin-turbo V12, and a new Alpina B7 to feature a more powerful twin-turbo V8 with around 600 horsepower. In parallel to the Alpina, however, C/D reports that an M Performance model could finally be in the works, which would ostensibly offer BMW the opportunity to go after the likes of the Audi S8, Jaguar XJR, and Mercedes S63 AMG, without changing tacks too drastically over the resolute position it's taken in the past against creating a full-on M7. C/D reports that there are more powerful diesels joining the lineup in the future, but those aren't likely to make their way to US showrooms anytime soon.

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.
