I put a list of the differences with the 220 and facelift 220 in the 220 trophy register blog. Mechanically they are identical. The Akrapovic doesn't improve performance, but does improve noise (but pre facelift noise still nice when putting the foot down).
The main differences to the RS200 are the turbo, larger air intake, faster steering rack, lower ride height, different spring rates, different roll bars, shorter travel on paddles, different gearbox software, stop/start (now on all facelift models), different exhaust, Michelin Pilot Super Sports, some software settings.
The update model is a slightly nicer place to be inside, but pre facelift had unique seats with Trophy logo.
All of the release info said a larger turbo and on one of my posts I did actually find the model. I think physically it is the same size, but it spins faster (different model to RS200).
I believe it is very similar to the NISMO Juke motor, but with more power.
And the ride? Well it depends on what you are used to. I find my wife's Liberty too soft. I think it is better than my previous Megane Cup. The hydraulic bump stops really stop the car crashing over the bumps, but the car is firmly sprung. Personally I think it suits the car. Very relaxing to drive on the highway if that helps.
Fastest regular production Clio built so far. Almost as fast as the stripped out R26R at the Nurburgring. I seem to recall Motor Mag recorded a 6.4s 0-100km/h. But of course it is all about the corners. Check out FastestLaps.com.
I knew the facelift was coming when I bought mine and I do like the update lights, but I got a good price. Mind you I do like that RS18 all in black. I notice some damn good prices going around for the pre facelift, including some basically new ones. Full retail on one of these is over $42000, which is a lot of money. If I had to replace mine, I would save the money and buy a pre facelift one. And I do like the diamond cut wheels better!
