Leaked Images Show Former Design for Siri in the Car?

Developer Steven Troughton-Smith has posted photos of what appears to be a former design for Siri in the Car.

Troughton-Smith tweeted "~7 months old (former design?)" alongside the images shown below.

Yesterday, he leaked several screenshots of what may be the current design for Siri in the Car. Apple is expected to release the feature sometime this year, perhaps with iOS 7.1?


Take a look at the photos below and let us know which design you think is best in the comments.
