It produced 708 kW (950 hp) and was used by the Regia Aeronautica for fifteen years to power their Fiat BR.2 and BR.3 bombers.

When Fiat were advised by the government to simplify their water-cooled product line, they focussed on the A.20, A.22 and A.30 models, so the A.25 was not further developed.

They concentrated their higher power development effort on radial engines instead.

[3] The only series produced types powered by the A.25 were the Fiat BR.2 and BR.3 single engine bombers.
