sentences:  The Jupiter achieved competition success with a record-breaking class win at the 1950 Le Mans 24 Hour race, a class one-two in the 1951 Monte Carlo International Rally, an outright win in the 1951 Lisbon International Rally, and a class one-two in a gruelling four-hour sports car race on the public road at Dundrod Circuit in Northern Ireland in September 1951.This was a resurrection of the famous Ulster Tourist Trophy races of 1928-1936 previously run on the Ards circuit.Le Mans was again class-won in 1951 and 1952, and lesser events were taken in 1952 but by 1953 newer faster cars were proving a match for the Jupiter which was after all a well-appointed touring car first and foremost.
