We propose some images that reveal the presence of the famous vehicle of the Halo franchise, the Warthog, racing in Forza Motorsport of the expected 4. The version of the vehicle in the game will be Halo 4, and appear only in Autovia mode, so it will not be driveable, but with the support we can explore the device Kinect to admire its features while Cortana, the Master Chief's AI companion, there illustrate the features. We leave you with images.

Update: there is now a video showing the vehicle mode Autovia Force. I'll show below.
