- Fiat-Abarth OT 2000 Coupé America: introduced in February 1966, it was based on the 850 Coupé but powered by a two-litre engine.[18] It differed visually from the 850 Coupé in having a barred grill between the headlights, a split front bumper flanking a spare wheel which projected forward below the grille,[18] widened front and rear tracks and wings, and a vented front bonnet. The 1946 cc twin cam four-cylinder produced 185 hp (136 kW) and could propel the car to 240 km/h (149 mph).[15][19] Three examples were produced.[20]
Seriously one problem may be engine direction of rotation limiting choices available.
