Jowett Javelin


The Jowett Javelin was an executive car which was produced from 1947 to 1953 by Jowett Cars Ltd of Idle, near Bradford in England. The model went through five variants coded PA to PE, each having a standard and "de luxe" option. The car was designed by Gerald Palmer during World War II and was intended to be a major leap forward from the relatively staid designs of pre-war Jowetts. Just over 23,000 units were produced.

All steel and new right through

The new Javelin, not yet in full production, made its first public appearance on Saturday 27 July 1946 in a cavalcade to celebrate 60 years of the British Motor Industry organised by the SMMT. Started by the King in Regent's Park the cavalcade passed through Marble Arch around London's West End and Piccadilly Circus and back up to Regent's Park. Series production was not fully underway until November 1947.
In a 1949 road test report The Times' correspondent welcomed the Javelin's good performance and original design. The engine mounted ahead of the front axle briskly accelerates a body which could carry six persons. The moderate size of the engine, the car's light weight and good streamlining all contribute to its excellent performance. Controls were all light to operate and it was a restful car to drive.

Powertrain

The flat four overhead valve engine of 1486 cc with a compression ratio of 7.2:1 was water-cooled and had an aluminium block and wet cylinder liners. It developed at 4100 rpm giving the car a maximum speed of and a 0- time of 13.4 seconds. Two Zenith carburettors were fitted and PA and PB versions had hydraulic tappets. The radiator was behind the engine. A four-speed gearbox with column change was used. Early cars had gearboxes made by the Henry Meadows company. Later, Jowett made the gearboxes, but the decision to make the gearboxes in-house proved to be a costly mistake. Even though Jowett had some experience in transmission manufacturing, the project went disastrously wrong; powertrainless bodies stacked up in the assembly line because of problems in gearbox production.

Design features

Design features included aerodynamic styling with the headlights faired into the wings and, for the time, a steeply sloped, curved windscreen. The body was of pressed steel, incorporating a box-section chassis, and was made for Jowett by Briggs Motor Bodies in their Doncaster factory. The suspension used torsion-bars on all wheels and internal gear-and-pinion steering. PA and PB models had mixed Girling hydraulic brakes at the front and mechanical braking at the rear. Later versions were fully hydraulic.

Dimensions

The car had a wheelbase of and a track of. Overall the car was long, wide and weighed about a ton depending on model and year. The car was expensive, costing £819 at launch.. The Jowett was competing against cars such as the Jaguar 1½ litre, Lanchester LD10, Riley RM 1½ litre and the Singer Super 12.

Performance

A de-luxe saloon version tested by The Motor magazine in 1953 had a top speed of and could accelerate from 0- in 20.9 seconds. A fuel consumption of was recorded. The test car cost £1207 including taxes.

Sporting achievements

An early example won in its class at the 1949 Monte Carlo Rally and another won the 2-litre touring-car class at the Spa 24-hour race in the same year. In the 1952 International RAC Rally a Javelin again won its class and also took the "Best Closed Car" award, and in 1953 the International Tulip Rally was won outright by a privately entered Javelin.
