There are some differences in the suspension, steering, brakes and the ECU is different, plus they are 89kg lighter.
Having driven both a mk2 172 and a Cup for a good few miles (mates Dad owns local Renault dealer) I was surprised how different they were...
The Cup is a sharper drive than the normal 172 and there is more of a surge at 5000rpm, when it comes on cam, like the older mk1 did, but you still get more low down grunt that the mk2 has, but the mk1 lacks.
I nearly bought one...
