Automakers teaming with Google to bring Android to cars this year

Remember how we mentioned that Hyundai would be offering a BlueLink infotainment app for Google Glass? And how last week, we told you about a rumored partnership between Audi and Google? Well, both of these things were just part of a much bigger deal.
Google has teamed up with Audi, General Motors, Hyundai and Honda to form the Open Automotive Alliance. With the help of chipmaker NVIDIA, the group aims to bring Google's Android operating system to the auto industry on a large scale. While the speed with which Android will be adopted by the industry remains unclear - the OAA's own press release says "timing for each automaker will vary" - we could see the first Android-equipped vehicle by year's end.
For those that keep their ear to the ground in the automotive tech world, this is a big deal for more than just one reason - Honda, GM and Hyundai are all partners in the Siri Eyes Free program from Apple. The future of that relationship now that three of its automakers are in bed with Apple's arch-rival, though, could be under threat.

Audi spotted running R8 E-Tron at the 'Ring

An electric version of the original Audi R8 may never have come to fruition – at least not in a form you could actually buy. But with the introduction of the all-new, second-generation model, Audi is getting serious about the prospect of producing the R8 E-Tron. And if you don't believe it, just look at these latest spy shots. Spotted testing at no less punishing a location than the Nurburgring is the upcoming new 2016 Audi R8 E-Tron. It looks just like the one we saw in Geneva earlier this year, painted in that same shade of electric blue, which we think suits the car rather well. It even has that orange strip of lighting around the side intakes, which drives the point of its electrification home in a rather stylish way, too. This prototype is wearing different wheels, and looks like it has some testing equipment mounted inside. Otherwise, this is pretty much what we can expect to see when Audi begins selling its electric supercar. We're sure there are more than a few eagerly awaiting customers who want to get their hands on an EV different from the Teslas or Nissan Leafs every other tree-hugger in the neighborhood has plugged in to their garages. To that end, expect the order books to open sometime later this year or maybe early into the next. Then the dream of an electric coupe with 456 horsepower and 679 pound-feet of torque, good for a 0-60 time in the three-second range and capable of tackling the Nordschleife, will finally become a reality. In the meantime, you can check out a piece of the action in the image gallery above.
