Handling is subjective as such, just because a car has more mechanical grip and can corner faster, it may not actually be the better handling car of it does not communicate it's responses back to the driver giving them the ability to react to that information.
While driving the Mk8 in the video Sutcliffe highlights it's capabilities, but lack of communication comparing the steering response to a video game.
He hardly slated it, but appeared to favour the mk7 on balance. Now if he had compared a mk7 Ed40 or CS-S at the test track, it may have been more decisive?
Sutcliffe has years of experience and is more than handy behind the wheel, I am yet to drive a Mk8, but having owned Mk1, 2, 3,5 &7, I found this comments on the earlier cars accurate, particularly his remarks on the wallowy Mk3 and it's long suspension travel.
