William Lyons’ masterpiece. In a series of articles, we celebrate an automotive high watermark as it marks its 50th anniversary.

“Without any doubt at all, the XJ6 is my personal favourite. It comes closer to than any other to what I always had in mind as my ideal car.” Sir William Lyons.
One bright spring morning in 1967, two men strode towards a lock-up garage in the grounds of an imposing Victorian stately home, amid the rolling Warwickshire countryside. As the dew shimmered on the immaculately tended lawns and borders of Wappenbury Hall, Sir William Lyons, Chairman, Chief Executive and spiritus rector regarding all matters aesthetic, led his European Sales Director, John Morgan to where Jaguar’s vitally important new car lay sequestered, in seemingly definitive prototype form.
An autocrat to the tips of his highly polished brogues he may have been, but Lyons nevertheless regularly canvassed the opinions of those he trusted, although having done so, he would for the most part, take his own council.
Unfastening the gate, Sir William reveals the secret new Jaguar. “Is that going to be alright for you,” he enquires. Aghast at what he later described as a “really bland” grille arrangement, Morgan articulates the first thought that enters his head, indelicately suggesting that it looks like a 1955 Studebaker. Lyons is horrified, and demands an explanation. Morgan stands his ground. “Well, it does, Sir William, it’s that solid front.” Intensely irritated, the Jaguar Chairman dismisses his subordinate and mulls the matter over.
A few days later, Morgan is once again summoned to Wappenbury to view the now-revised XJ prototype. “I’m not going to do anything more to it,” Lyons insists, as he reveals the altered treatment. “Now Morgan, he demands, does it look like a Studebaker?” Sir William had instructed every second horizontal bar to removed from the grille, creating the definitive crosshatch arrangement for which the XJ6 is synonymous.
Not all great art is created by a lone genius and while the Jaguar XJ6 was clearly not the work of Lyons alone, the libretto was orchestrated and minutely directed by him. It is comparatively rare for a creative peak to occur towards the close of one’s career, but XJ6, while perhaps a logical culmination of fifty years in the business of art and commerce, was conclusively both Sir William and Jaguar’s finest opus.
Undoubtedly the definitive Jaguar; it cemented an image of the marque for over half a century, one which retains a strong relevance today. Unquestionably the most significant car in the marque’s history, and equally, its best realised.

Aesthetically, an inspired distillation of Lyons’ decades of stylistic experimentation, conceptually, a groundbreaker, and dynamically, the most accomplished Jaguar saloon then made. Yet the car which launched to such lavish acclaim in September 1968 deviated markedly from that which was originally envisaged.
Sir William Lyons began sketching out a ‘four-seater E-Type’ as early as 1961, having realised first hand at that car’s US launch that its cabin was simply too cramped. But what began initially as a long-wheelbase E-Type soon morphed into a different animal entirely.
With Jaguar’s US distributors agitating for a pillarless 2-door rival to Buick’s elegant 1963 Riviera, Lyons expanded his ideas into a vehicle (dubbed XJ4) which in appearance combined the production centre section, with an E-Type inspired nose and tail. A version of this was released to Pressed Steel Fisher (who carried out the bulk of Jaguar’s body engineering) as early as April 1962, but was not proceeded with.
Between 1961 and 1964, Lyons appeared to prevaricate, before electing to proceed with a version of the car in both two and four-door form. Meanwhile, he evolved the styling, first with a more formal and upright nose treatment which reflected that of the contemporary Mark Ten, and then at the tail, where the rounded E-Type treatment was abruptly foreshortened.
After that it would be the habitual trial and error before the definitive style emerged, with Sir William the sculptor painstakingly teasing out the nuance buried within. The car’s engineering package also informed its style, the wide wheels and low-profile tyres helping define the car’s appearance, with the body stretched tautly around them.
Having eschewed a more traditional sharply falling bodyside crease for something a good deal more subtle and linear, and utilising the car’s broad track to define its stance, the definitive XJ combined a athlete’s muscularity with supreme confidence and grace.
XJ4 benefited from Lyons’ magpie eye, its body style combining elements from previous Jaguar saloons, alongside those of the Italian carrozzieri in the delicate canopy treatment, and Jaguar’s resident aerodynamicist, Malcolm Sayer’s E-Type, in surfacing and form language. But it was how Sir William’s cohort of gifted metalworkers (under his watchful guidance) treated these elements that led to such outstanding results.
In terms of proportion, stance and overall form; in the relationship between body and canopy, and the manner in which these various stylistic elements were melded, the XJ6 remains a masterclass of understated flamboyance. To emphasise this interplay between exaggeration and restraint, no identifying script appeared on the early cars whatsoever, apart from badging which denoted engine capacity.
But even in this seemingly inviolate arena, difficulties arose. With Lyons’ 1966 market research illustrating that pillarless bodies were outselling saloons by a fifty percent margin in the United States, it was felt that Jaguar should prioritise the 2-door version, with their US distributors informing them they were only interested in this model. However, in Autumn 1967 Pressed Steel stopped work on the two-door XJ4 body owing to BMC’s Maxi gaining a priority slot. But with Jaguar now a subordinate cog of the failing BMH combine, there was little Sir William could do.
But the setbacks didn’t end there. Having met with resistance over the grille treatment, Lyons would face an even more frustrating stylistic impasse perilously late in the car’s gestation.

How incredible, just last night I saw a beautiful S2 XJ6 in Camden Town,(below), and my first thought was “gosh, I wish Eoin would write an AROnline style article on these”, and lo and behold the following morning you do! Fantastic, lookig forward to the rest!
Apologies for my pedantry, but that’s actually a 1975 Daimler Sovereign 4.2 LWB with only 64K miles and the MOT has only just expired, on 10th August. Hopefully, it will be looked after properly.
IIRC, the Jaguar version never had the chrome strip on the side and rarely had vinyl roof coverings (except in the U.S.).
Not pedantry at all, you are quite right, on all counts! I was a passenger in a fast-travelling car when I spotted it, I barely had time to snap it (hence the rear three quarter view). Initially I thought it might be an XJC, courtesy of the vinyl roof, but of course then I noticed the four doors. I thought it must be an LWB but I never noticed the chrome strip, and it makes sense that the vinyl roof should be a Daimler feature due to its contemporary association with luxury. I don’t normally like the vinyl roofs, but in this case I have to say I think it really emphasises the lowness of the shape.
Unlike many other designers, Lyons seemed to be able to develop his ideas over a long run under one roof. Painters and composers can do this and it means you can see a progression over time as their work constitutes a kind of long running project where themes are developed. Lyons´ cars constitute his attempt to show his ideas for the his ideal cars. That anyone wanted to buy them was almost secondary. That is why the XJ is such a rarity: it is the result of decades of thought about a specific notion of the car. Everyone else has to be opportunistic and almost never has any chance at continuity.
Richard, while it is true that Sir William had a singular vision (if not as extreme as Bugatti’s), even a serial XJ owner (sufferer? – S1 Daimler V12, S2 XJ6, S3 Sovereign V12 and, not in quite the same breath, 2 x X300s) has to admit that there are one or two other reasons for relative rarity, mainly reputational.
They are exquisite, but flawed devices; the best description ever in my view being David E Davis’s Car and Driver piece in which he compared a Merc to a machine tool, a BMW to a good camera and (I paraphrase slightly here) the XJ to your favourite mistress’s best silk knickers. Worth the odd glitch, then.
For good or for ill, Lyons certainly took his time. There was nothing wrong with the rationale that a four door E-Type was a saleable concept, and the photos of prototypes in this mode that have surfaced (one being shown above) certainly bear this out. Jaguar could have launched that car much earlier and still gained all the plaudits, whilst easing Jaguar’s troubled cash flow so that it did not fall into the hands of BL.
There is also a lesson here for the future. I have said this before but I will say it again: the XJ should be a coupaloon version of the F-Type. A car like that would sell at a premium any day of the week.
I too saw an XJ6 recently, an early one, puzzling at the apparition (front on)
in the distance, its now radical proportion of width to height, before recognition.
Indeed a beautiful thing, and a poignant commentary on contemporary styling.
Lyons had decades to work on the idea before getting to that point. One could write quite a lot about why that car is beautiful and demands repeated viewing. Perhaps the interest comes from the idiosyncracy of the designers´ vision.
