I honestly think it's Clarkson at fault here. He spoke nothing about the 3 modes the steering has along with the other settings that change the handling. Other video reviews I have watched go into some detail about them but I wouldn't be all surprised if JC just left it at default especially when he talked about the EDC settings on the M3.
He does have a hate for Audi after all!

Odd how the RS5 wasn't understeering to any noticeable manner when driven properly. Whilst there is no doubt it does, 90% of the 'public' watching Top Gear last night will now believe all RS5's will wash out by 20 feet when you simply turn the wheel off centre. The amount of times I've had someone at work, in the pub, in a shop talk about something utterly stupid they saw on Top Gear as if it were fact is beyond scary. Cardboard boot in the CSL etc etc etc
It was a little odd that. It was Clarkson at his lazy-review best, like when he did a hatchet job on the Vauxhall Vectra VXR by simply turning the wheel and flooring the throttle and acting surprised when a FWD powerful car understeers

I heard James May on Christian O'Connell's 5 Live show on Sat morning and he admitted that one reason they don't do 'normal' car reviews is that he doesn't actually know very much about them! Whether that was said tongue in cheek is another matter...
I thought the show was not bad, but perhaps a little below par. That said, as Fox and others have said, haters gonna hate & I MUCH prefer this Top Gear to the old style with Chris Goffey reviewing the Almera diesel and Quentin Wilson going on about used car prices. Perhaps that was one reason why Jason Dawe was binned after S1?
