well for a start JT confirmed it will be n/a, so rules out the possibility of the 225 engine, meaning i'd expect a moer stressed and modified f4r engine to be supplied
as edde says, around 190-195bhp is expected, they don't want the clio to be too much quicker than the flagship megane
trev - i expect it may use a box similar to the megane so as they can use the 6th gear the 182 should have had, i don't think size is much of an issue for the new clio though as the car appears quite a bit bigger than the previous model
