This spider version of the 308 GTBi shared both its line and engine. The fuel injection system gave both models much smoother power delivery. Unfortunately, meeting anti-pollution regulations meant that a few horses had to go, and the cleaner engines were less powerful than the previous carburettor ones. Aware of this situation and the need to re-establish its cars at the top their class, Ferrari immediately began further development of the V8 engine with the aim of increasing power whilst still keeping exhaust emissions within acceptable levels.
