I prefere TC engines more, but if they want the Clio to remain N/A, than make it 100kg lighter, and with REAL 210bhp, and it would be a rocket.
However, with all those downsizing & ecology, they will probably install a downsized TC engine. 1.6T with 210bhp maybe? I don't think they would go for a 2.0T engine (although they could easily use a Megane R26 engine with the modified gearbox, and LSD) although it would be a BOMB! IMHO.
EDIT: 1.6T engine with ~210bhp - I don't think it's a good base for further tuning given in mind already good power on such small engine...of course, if they really decide to go that road.
But, with the R26 engine/gearbox/LSD in some Clio special edition (R28 maybe?
) this Clio would be very close to the current Megane RS. And with some tweaks that are already known when it comes to the R26 engine, it would be more fun to drive and faster....uhhhh....got me drooling now and it's not the Christmas lunch cooking...
