The
Cupra R has a stronger front subframe, different suspension and steering compared to the
Cupra. There are many detail differences and the handling is very different. The
Cupra R has the Audi S4 front assembly whereas the other cars have what I assume is the standard Golf/Audi A4 set up.
Having owned both
Cupra and
Cupra R cars, I've noticed a difference in the way the turbo delivers power too. The 180bhp cars are fitted with the K03 turbo, while the R has the larger K04 turbo. Clearly the R is more powerful and faster, but I've always found the cars with the K03 turbo respond more quickly initially when the throttle is opened.
