Depends which year model you are buying.
2008 onward Cupras have over the FR black grille, nicer wheels, bigger/better brakes, uprated suspension, black interior,
Cupra badging, better seats (although FR seats are similar in newest cars), gloss black pillars on side, front bumper with black trim at bottom, oval exhaust, 40bhp more power with little difference in C02 or economy, ability to map up 60bhp to 300bhp where FR will only map to what the
Cupra starts at.
Early cupras (2007 models) had Xenons as standard and silver grille.
The only thing the FR offers over the
Cupra is DSG option on petrol models, and the diesel engine option.
