1970-1974 TRIUMPH Spitfire Mark IV specifications


Michelotti restyled the Spitfire for the 1970s using many cues from the recently launched Stag. Only the sills and door skins were carried over from the MkIII, A change to swing-spring rear suspension made a vast difference to roadholding. The engine is often said to have been de-tuned from Mk3 spec, but in fact only the system of measuring output changed – from SAE to DIN – so the drop from 75bhp to 63bhp was not a real one. The MkIV was slower though, thanks to both extra weight and the taller gearing used to improve economy.
