It was the unlikeliest of vehicles from the unlikeliest of automaker. It was the Jowett Jupiter, the one sports activities automobile constructed by Jowett Cars, Ltd. — a longtime British producer of 2-cylinder vehicles.
Introduced this week on the London Motor Show in 1949, it could go on to attain class wins on the 24 Hours of Le Mans and Monte Carlo International Rally.
But it did little to avoid wasting the corporate from extinction.
A modest begin

Our story begins when brothers Benjamin and William Jowett started manufacturing V-twin engines on the flip of the earlier century.
They went on to ascertain the Jowett Motor Manufacturing Co. in 1901 in Yorkshire, England, initially constructing bikes till they created their first prototype automobile in 1906. It would enter manufacturing in 1910. The firm reorganized after World War I, changing into Jowett Cars Limited, constructing 3,500 automobiles in a superb 12 months.
To generate cash, the Jowetts tried to go public in 1935, however their proposal was rejected. As a consequence, Charles Calcott Reilly took management after the brothers retired. Reilly added two extra cylinders to the Jowett side-valve flat 2-cylinder engine, whereas nabbing contracts to supply flat-twin-powered turbines throughout World War II.
But Reilly started considering the postwar market. He surmised that British market demand could be minimal, that means the corporate must export vehicles to proceed working. For that, he would a automobile designer.
Reilly discovered him in Gerald Palmer, then working MG’s design studio. Palmer joined Jowett in January 1942, the place he would get pleasure from an intensive quantity of freedom in creating vehicles, along with his first task being the creation of a six-passenger sedan.

A brand new automobile’s beginning
It arrived in 1946. Dubbed the Jowett Javelin, the looks of the brand new sedan revealed Reilly’s fondness for the Lincoln Zephyr. The automobile’s cabin proved notably spacious because of its aluminum 1.5-liter overhead-valve horizontally opposed 4-cylinder engine, rated at 50 horsepower.
Three years later noticed Palmer returning to MG, whilst Aston Martin’s Roy Lunn joins the agency as an engineer. Lunn had labored on the Aston Martin DB2, and would go on to grow to be the chief engineer for the Ford GT40.
He could be joined at Jowett by former Auto Union engineer Eberan von Eberhorst, whose credentials embrace the 1938-’39 Auto Union Silver Arrow 3.0-liter Grand Prix vehicles.

At Jowett, Lunn set about redesigning the Javelin’s entrance suspension with the considered producing a two-seat roadster in an effort to duplicate the MG TC’s success in America.
So, the corporate used the Javelin’s engine, transmission and suspension in a brand new tube-frame chassis and cloaked it new sheetmetal. For the brand new two-seat roadster, the engine was positioned forward of the entrance axle, with the radiator mounted behind it. It additionally bought an additional shot of juice, now rated at 60 horsepower.
The ensuing automobile, the Jowett Jupiter, debuting on the London Motor Show this week in 1949 sporting rack-and-pinion steering, mechanical brakes and curvaceous clothes. Weighing 1,500 kilos, the Jupiter might run 0-60 mph in 15 seconds.

Certainly, the automobile got here as a shock; the corporate had by no means constructed a sports activities automobile. But the little roadster proved very aggressive, attaining back-to-back class wins on the 1950 and ’51 24 Hours of Le Mans, in addition to first and second at school and sixth general on the 1951 Monte Carlo International Rally.
What occurred subsequent
While theJowett Jupiter might attain speeds of greater than 90 mph on the monitor, on the road, they proved extra problematic.

Tom McCahill, the influential automotive journalist for Mechanix Illustrated, wrote on the time that the Jupiter “dives into corners like a porpoise with heartburn and the steering is like winding an eight-day clock with a broken mainspring.”
Bad evaluations apart, the Jupiter tended to overheat, the transmission proved unreliable and the entrance suspension was inclined to interrupt. Chronically unreliable, each the prettier, extra dependable and equally priced, Jaguar XK120 and cheaper Austin-Healey doomed the Jowett Jupiter’s possibilities.
As if that wasn’t dangerous sufficient, gross sales of the Javelin sedan began falling off, and the Jupiter did little to compensate. But then, issues bought worse.
In 1953, the British authorities lops 25% off the acquisition tax on new vehicles, resulting in a surge in demand. The uptick leads Ford Motor Co. to purchase Briggs, which provided our bodies for Jowett. Facing a scarcity of our bodies, manufacturing stops in July 1954, after 825 Jupiters had been constructed.
The Jowett manufacturing unit is offered to International Harvester, which makes use of it to supply farm tractors. By 1955, Jowett is historical past.
