I have owned both for long periods of time, and my mate has a vRS, and another a 182, when I had the 172 we often went for spirited drives, I guarantee there is nothing in it straight line speed. 0-60 times mean s**t but bragging rights, if you were rolling at 30mph in both it is dead even.
People depend far too much on stats, having never driven most of the cars they comment on.
People seem to think the Clio is some kind of unbeatable power machine, and can't hack that their shitbox cars aren't the fastest car on the road, especially against a Skoda diesel. But I guess you would get that on a Clio forum.
