220km/h is not a low topspeed for a ~200hp car with that shitty aerodynmaic. Means the gearing is set for topseed not for acceleration.
just to see the effect of the aerodynamic in combination with low power (by modern standarts)
sportauto tested the car with
north of 160km/h the car simple lack the steam to acclerate faster
the 1992 220hp Ford Escort Cosworth with sligthly more power and much better aerodynamic needed
and reached thanks to the better shape a slightly higher topspeed with 234km/h
the 1992 208hp Toyota Celica Turbo 4WD Carlos Sainz Edition
0-180km/h in 26.0s
0-200km/h in 40.4s
again thanks to better aerodynmic it reached a slightly higher topseed of 230km/h
the 1993 Celica GT4 with 240hp still needed 30.2s 0-200km/h
no way this Integrale can get to 200km/h in 22s only if tuned ~ 300hp
22s 0-200km/h is WRX STI, Evo IX, TT-S, NSX range of cars...
