In 1965, AC showed the powerful, Frua-bodied 7-litre AC Frua Spyder, which drew from the Mistral's shape. A coupé followed in 1967. In the same year, the Swiss racing driver and Ferrari importer Peter Monteverdi started to build a Frua-bodied sport coupé, the Chrysler engined Monteverdi High Speed 375S. He also designed the Monteverdi 2000 GTI, but this remained a one-off. Due to Frua's limited capacities, the production of the following High Speed models went to Fissore in Turin. However, the Monteverdi Hai 450 is believed to have been designed by Frua.
