The history of the model IF Tipo 8A

The Isotta Fraschini 8A was a car manufactured by Isotta Fraschini, successor to the Tipo 8 model with a new 7.3 litre straight-eight engine to replace the 5.9 litre unit used in the previous model. This new engine could produce 115–160 brake horsepower (86–119 kW).

This was the most powerful mass-produced straight-8 engine in the world at that time.

The Tipo 8A was offered only with bare chassis and engine for the coachbuilders.

The Isotta Fraschini car company promised that every car could do 150 km/h (93 mph).

The car was very luxurious and it cost more than a Model J Duesenberg. Around one third of these cars were sold in the United States.

The Tipo 8A's displacement was up to 7.4-liters, overhead valveoverhead caminline 8. Like the Tipo 8, there was no exterior intake manifold, instead the twin carburetors attached directly to the block. Transmission is a three-speed manual. The 8ASS (Super Sprint) package was also an option.
