The final production variant was the "BR.20bis", which was effectively a complete redesign of the aircraft. It featured a fully glazed nose, a retractable tail wheel, and more streamlined fuselage, pointed fins, although the principal change involved was increased engine power from a pair of 932 kW (1,250 hp) Fiat A.82 RC 42 radial engines, along with an improved and heavier armament. The nose held a simple machine gun position rather than the turret used on earlier aircraft and two waist blisters were fitted over the wing trailing edge while the dorsal turret was a Breda Type V instead of the earlier Caproni Lanciani type. The BR.20bis was considered to be an improvement over the previous versions, particularly in terms of its aerodynamics. However, plans for production was delayed, in part due to technical issues that took time to resolve, and a decision by the "Regia Aeronautica" to place large orders for the competing CRDA CANT Z.1018 instead. Originally, 98 aircraft were ordered, but only 15 BR.20bis were built from March to July 1943, with heavy Allied bombing of Fiat's Turin factory preventing further production. There is no evidence that any of these were deployed under operation circumstances.
