Announced today at WWDC 2013. All these badges will feature the functionality next year. Hopefully including Corvette 7.
Apple has been teasing an extra level of integration with cars beyond the likes of iPod Out or Siri Eyes Free, and it just gave us substantially more today. A new iOS in the Car feature will directly link iOS 7 with cars' infotainment systems, giving drivers an optimized interface for maps, messages and music. They'll be waiting awhile to plug in, however, as a number of automakers (including Ferrari) only expect to implement iOS in the Car sometime in 2014.
