1951 Jowett Jupiter

Jowett Jupiter Restoration

The Jupiter was produced in limited numbers between 1950 and 1953 by Jowett Cars LTD and was the second postwar model built by the company, following the Javelin sedan. Jupiter was first shown at the British Motor Show in New York in April 1950. It was announced as “the race-bred, high speed 3-seater” and in fact enjoyed some racing success: In its inaugural race outing, a lone Jupiter claimed a class victory at the Grand Prix d’Endurance at Le Mans in June 1950, averaging 75.8 MPH for 24 hours. Another Jupiter took class honors at the 1951 Monte Carlo Rally.

Approximately 46 Jowetts were sold in the U.S. in 1951.

This example was imported by Max Hoffman on 19 March 1951.

Its four known owners have all resided in Maryland.

The current owner acquired the car, barely running, in 1972.
