The origin story is delightfully unglamorous. Born in the seaside town of Blackpool in 1901, William Lyons was the son of a piano repair man. However, as he grew, the young Lyons was not smitten by Blackpool’s numerous theatres and music halls, but by what was happening on the streets outside. The cars and motorcycles that were becoming more commonplace were what excited him. Despite his headmaster’s warning that he ‘would never get anywhere messing about with engines’, he bought his first motorcycle, a 1911 Triumph from an older schoolmate, which he rebuilt to his own design. When the Walmsley family moved in up the street, William’s eye was caught by their son’s homemade sidecar, a streamlined polished aluminium body on an ash wood frame. William Walmsley, a veteran of World War 1, was nine years older than Lyons and had learned the basics of bodywork by helping his coal merchant father build wagons in his yard. The sidecar was a similar shape to the Zeppelin airships which were thrilling the world following the war.
Lyons suggested that they go into partnership to manufacture the sidecars. Walmsley was lukewarm about the idea; he was happy to lead a leisurely life and make the odd sidecar for friends as a hobby. Walmsley’s parents were concerned by this attitude, and supported Lyons in trying to persuade their son, and eventually, with a £1,000 overdraft guaranteed by the two fathers, the Swallow Sidecar Company was created in 1922.
The Swallow Sidecar Company made a name for itself by doing the simple things exquisitely: clean lines, good fit, and a sense of style that lifted the product beyond mere utility. Within four years, they were producing over 100 units per month, however William Lyons only saw sidecars as a stepping stone to his ultimate dream.
The partnership with William Walmsley was an odd one: Lyons was restless and commercially alert; Walmsley deliberate and faintly reluctant. Yet the combination worked, particularly once the business moved from sidecars alone into the equally modest business of building bespoke bodies for Austin, Morris and Standard chassis. Retaining the standard chassis and running gear, Swallow did not make cars any faster; it did, however, make them look faster, longer, and better resolved, a lesson Lyons absorbed completely. By the end of the decade, he understood something British manufacturers would take another twenty years to learn properly: aspiration sells.
The Swallow car bodies were a hit, yet that soon lead to problems. Lyons was getting complaints about the sheer numbers of chassis from the Austin works at Longbridge which were rolling into Blackpool Talbot Road station, completely congesting the goods yard. In 1926, Lyons convinced Walmsley that the solution was for the Swallow factory to move to Coventry; by then Britain’s answer to Detroit; a legacy of the city’s 19th century clock and bicycle makers from which Britain’s car manufacturers had emerged.
In 1931, Lyons designed his first complete car, a graceful coupe named the SS1, using a chassis and engine supplied by the Standard Motor Company. A few weeks before its launch, he was taken ill with appendicitis. Upon his return, to his horror, he found that Walmsley, concerned by the practicalities of the low roofline, had raised it a couple of inches. Lyons was furious; “The effect was ruinous to the appearance. The door sill line was two inches above the scuttle and the bonnet, giving the top a conning tower look… I hated it and felt very depressed”. For him, the styling of the car was everything, even if it meant sacrificing some headroom. It was too late to change it back before the launch, and thankfully it didn’t dampen the enthusiasm of the motoring press. The Daily Express praised its “£1,000 look” although it only cost a mere £310. Soon after this episode, Lyons parted ways with William Walmsley, who went on his own to build caravans. From then on, Lyons was solely in charge with no interference.
By the mid-1930s, the business was trading as SS Cars, and the company’s own models -most memorably the 1935 SS Jaguar saloons – hinted at performance with a polish uncommon in the class, but, with archaic four- and six-cylinder Standard engines, didn’t have the performance to back up the sleek looks. Some of the motoring establishment dismissed them as ‘Wardour Street Bentley’s’, an unkind dig at the less than respectable Soho base of the emerging British film industry. Lyons knew that to gain real credibility, he needed to design and build his own engines from scratch. He began recruiting suitable talent, but then Hitler’s armies spoiled his plans by invading Poland.
By 1940, virtually all British car production was put on hold, as the entire industry was diverted to wartime production. Any development for future models was also forbidden. As the government had now become his sole customer, Lyons couldn’t afford to fall foul of the rules, so he went undercover.
Firewatchers were volunteers on the home front who were charged with keeping watch for blazes caused by incendiary bombs. Lyons volunteered for Sunday nights and arranged for three other volunteers to join him: Bill Heynes, Claude Baily, and Wally Hassan.
He had hired Heynes from Humber to be his chief engineer in 1934, before SS Cars even had a drawing office, but Heynes found his approach irresistible, as his new boss told him that he aimed to build ‘one of the world’s finest luxury cars’.
Claude Baily was a designer that Lyons had attracted away from Morris with the promise of designing a new engine from scratch. Hassan was a wild card; taken on as a 15-year-old shop boy by Bentley, he graduated to be the mechanic on the Le Mans racer of Woolf Barnato, one of the famous ‘Bentley Boys’. With his experience of exotic, hand-built machines, he was an unlikely choice for a company gearing up for mass production, however Lyons was impressed by his skills at extracting more power from the Standard-derived engine in the SS100, and Hassan’s skills were perfect for what Lyons had in mind – he wanted some of that Bentley magic sprinkled on his first in-house engine.
As they huddled together in the blackout, listening for bombers, Lyons laid out his requirements and ideas. No-one knew how long the war would last, or what to expect when it ended, but Lyons stuck fast to his plan for a truly high-performance model that he had promised Heynes that he would build one day.
To Baily’s and Hassan’s dismay, Lyons insisted that the new engine would be a twin overhead cam design, which was popular on European racing engines, but rarely seen on mainstream British machines. Hassan, who had seen such engines firsthand in his Brooklands days warned that such an engine would be expensive and probably fairly noisy too, but Lyons obstinately stuck to this requirement, and the requirement that the engine had to be as good looking as famous racing engines of previous years, so when you opened a Jaguar bonnet you would be looking at power and be impressed. Lyons, always with an eye for style, even cared how his cars looked under the bonnet.
Knowing that the boss always got his way, Hassan and the others fell into line, and began planning on scraps of paper the engine that they would go on to build after the war.
A month before VE Day, with the initials ‘SS’ carrying unavoidable associations, William Lyons changed the name of his company to Jaguar. The choice of the name was not accidental. A jaguar is not brutish; it is efficient, controlled, and supremely capable over distance. It would prove an oddly accurate metaphor. Jaguar emerged into a Britain short on materials but hungry for exports, glamour and speed. The company’s answer was not merely a new car, but a new heart: an engine that would carry Coventry’s ambitions all the way to the Mulsanne Straight.
The XK straight-six was the turning point. Conceived during the conflict and revealed to the world in 1948, it arrived wrapped in the XK120 – nominally a show car, quickly a production sensation – whose very name read like provocation. Here was a machine that looked expensive, went like a thoroughbred and, crucially, could be sold abroad. In those early post-war years, Jaguar learned to think in terms not just of style, but of sustained performance: speed that did not wilt, engineering that could take a hammering and come back for more.
It is no accident that endurance racing beckoned. Jaguar’s competition chief, Lofty England, understood the value of a French June weekend to a company selling cars to America. The C‑type made the point decisively. Light, disciplined and free of unnecessary ornament, it won on debut in 1951 and again in 1953, the latter victory marking the arrival of disc brakes as a racing – and soon road – standard. Jaguar’s contribution here was not novelty for its own sake, but proof under duress. If something worked for twenty‑four hours at Sarthe, it would work on the A‑road to Coventry.
The D‑type refined the argument into something unmistakably modern. Malcolm Sayer’s aerodynamics were not artistic flights but engineering solutions, born of slide rules rather than sketchpads. The monocoque structure, the stabilising fin, the relentless attention to airflow – all served a single purpose. The car was designed to be quicker for longer.
It won Le Mans in 1955, then repeated the feat in 1956 and 1957 – an era that also demands the sober reminder of the 1955 tragedy that changed the sport’s safety thinking forever. Through it all, the D-type remained the symbol of Jaguar at full voice: fast, efficient, and unflappably quick over distance.
That the final two wins came with private teams – most famously Ecurie Ecosse in 1956 and 1957 – only burnished the legend. Jaguar had created a machine so fundamentally right that others could take it to France and beat the might of the works efforts. Back in Coventry, the lessons filtered into the showroom: the disciplined cooling, the high-speed stability, the confidence in braking, the sense that a Jaguar ought to feel composed at an indecent pace.
Look back far enough, and the romance resolves into craft. The sidecar makers who cared about a straight seam and a clean curve became a car company that cared about airflow, weight, and the way a machine holds itself together after a long night at speed. Post-war Jaguar’s Le Mans years were not a lucky streak so much as a coming-of-age: proof that beauty could be engineered, and that elegance – properly understood – could win.
