We haven't seen new spy shots of the 2010 Ford Mustang for a while, so leave it to an Autoblog reader to have his camera at the ready when one flies by on the highway. Brandon R. took these pictures on an undisclosed road somewhere in the U.S. (that should narrow it down for you) and tells us that the driver wasn't very interested in smiling for the camera. After he realized that the car was being photographed, the Mustang jockey slammed on the brakes and promptly pulled over, but not before Brandon had taken his pics and recorded video of the Mustang showing off its passing power.

It's all speculation as to what's powering this prototype, but it appears to be a GT model if wheel size and two grille-mounted fog lamps are any indication. Out back are dual exhaust pipes and what must be a rear spoiler all covered up, as well. The hood features a big bulge, but don't get too excited as we surmise it's not to make room for some monster engine but rather keep the contour of the new hood a secret. Studying the front end, we also get a clearer view of the Mustang's new headlights as well as the lower air intake. All in all, Brandon did an excellent job in his impromptu debut as a spy photographer/videographer and we hope he spends more time with the cruise control on and his camera riding shotgun. Thanks for the photos and video, Brandon!

Don't forget to check out Brandon's video after the jump.
