We see them transform from their vehicular form to their "bipedal" form on the move numerous times in the movies. Several of these transformations happen at highway speeds (say 60-70 mph). Has it ever been established how fast they can actually run on foot? Obviously some would be faster than others so I'm looking for the fastest established or estimated foot speed.
I doubt if anyone has ever measured his speed, but Blurr is widely recognized as one of the fastest (if not the fastest) Transformer on foot. He's been described as being faster than the speed of sound on foot and clocking 800 MPH in vehicle mode.
