context_page_description: The Jowett Jupiter is a British car which was produced by Jowett Cars Ltd of Idle, near Bradford.
  Following the launch of the all new Jowett Javelin and its successes in competition, Jowett decided to use its power train in a sports car for export in the hope of increasing their inadequate steel allocation.
  The chassis only was displayed in October at the London Motor Show which opened 28 September 1949 and the complete car for the first time in New York in April 1950. Again the chassis only was given its continental launch at the Geneva Motor Show which opened 16 March 1950. It continued in production until 1954.
context_section_description: The flat four overhead valve engine of 1486 cc was more highly tuned than in the Javelin and had its compression ratio raised from  7.2:1 to 8.0:1 developing 60 bhp (45 kW) at 4500 rpm giving the car a maximum speed of 85 mph (137 km/h) and a 0-50 mph time of 11.7 seconds. Two Zenith carburettors were fitted. A four speed gearbox with column change was used.
