The Volvo P1800 is a 2+2, front-engine, rear-drive sports car manufactured and marketed by Volvo Cars between 1961 and 1973. Originally a coupé (1961–1972), it was also offered in a shooting brake configuration toward the end of its production (1972–1973). Styling was by Pelle Petterson under the tutelage of Pietro Frua when Frua's studio was a subsidiary of the Italian carrozzeria Ghia, and the mechanicals were derived from Volvo's Amazon/122 series.

Pelle Helmer Petterson is a Swedish sailor and yacht designer. He is the son of Helmer Petterson and Norwegian-born Borgny Petterson, and studied design at the leading Pratt Institute in New York from 1955 through 1957. His father was also a designer who developed wood gas aggregates and Volvo PV444, strongly influencing his son to go in his footsteps. He is probably best known for designing the Maxi brand of sailing boats, which are still among the most common sailing boats in Swedish waters. He also designed Volvo's successful sports car, the P1800, while he was a student of Pietro Frua.
