Sorry but this based on your experience driving how many of these?
I've driven both generations of the V6 and was lucky enough to be working for Renault at the time of the original cars launch.
First off the Wiki story is just that, a story, Renaultsport have a history of producing cars of this nature, as has been said already the Clio V6 is a succesor to the R5 Maxi. It was also the basis for a very good one make race series.
As far as the drive goes, in terms of straight line speed and acceleration the V6 was killed by its curb weight and the Mk 1 was also very tricky on the limit.
The Mk 2, while not being massively faster is a much better drivers car and it was not neutered in any way, in fact the revised suspension improved the cars handling massively.
As far as understeer goes, its a car that needs to be driven in quite a similar manner to a 911, its weight bias is strongly to the rear and does need a slow in approach.
In closing, yes the 182 is in many ways a faster car, but the world would have been a much poorer place without the Clio V6, it turns heads and sounds great.
