Jaguar Overview
In the 1920s, Jaguar (then called Swallow Coachbuilding Company) was making its money by creating motorcycle sidecars. It wasn’t until the 1930s that founder William Lyons started making car bodies, and then entire cars. By 1945, he had changed the company’s name to Jaguar Cars, Ltd. and had begun to make history.
In this article, you’ll learn all about some of Jaguar’s most famous models, starting with the Jaguar XK120. A sensation right out of the gate, the XK120 (which referenced its 120 mph top speed, incredibly fast for its day) combined exhilarating performance with incredible value, all in a sleek, futuristic package.
The E-Type was the pinnacle of the already legendary Jaguar lineup.
Continue on to learn more about the Jaguar lineup, from the early six-cylinder cars to the later twelve-cylinder roadsters, complete with car profiles and photos.

Jaguar XK 120
It’s no exaggeration to say the Jaguar XK 120 helped rejuvenate a nation’s belief in itself. Its seductive shape and magnificent engine brought acclaim -- and orders -- from all continents, reassuring Britons that their beleaguered island still could produce something of international value after World War II’s devastation.
A seminal sports car for both Jaguar and Britain was the XK 120. It used a
sedan chassis and a torquey new twincam six that proved an instant classic.
It wasn’t until after the war that his cars got their own engine, however: a 3.4-liter inline-six with an exotic-for-the-day twincam head and hemispherical combustion chambers. The work of Lyons’s chief engineer, William Heynes, this engine would be Jaguar’s soul into the 1980s. The six was strong and durable because it was intended for use in a sedan due in 1950. But Lyons knew there was greater publicity value in putting it in a new sports car.
Lyons always said he drew the XK 120 with a few quick strokes of the pen, although its basic shape could be seen in an experimental streamlined body he had done for the SS 100 in 1938. Regardless, the XK 120 was a masterwork, a low-slung roadster with pouncing-cat fender lines of disarming grace. Its underpinnings were less exciting: a shortened version of the heavy sedan chassis, independent torsion-bar front suspension, live rear axle, recirculating-ball steering, and drum brakes. No matter. Unveiled late in 1948, the car was an immediate sensation, especially at a price of around $3000.

Jaguar XK 140
So advanced and successful was the XK 120 that Jaguar didn’t need to replace it for a full six years, with the XK 140. This allowed the factory to get heavily involved in motorsports, producing the LeMans-winning C-type in 1951 and the wind-cheating D-type three years later.![]() Given the success of the XK 120, Jaguar made only considered changes to its successor -- and took pains to retain the overall styling. |
Standard horsepower increased by 30 to 190, same as the previous $800 “special equipment” package. An “M” package added wire wheels and fog lamps, while a new “C” option brought LeMans-proven C-type cylinder heads, which were painted red and gave the 3.4 -liter inline-six one horsepower for each of its 210 cubic inches.
![]() Total XK 140 production was 8884; 38 percent were roadsters and the balance was split evenly between Fixed Head and Drop Head coupes. |
In June 1955, Road & Track tested a $3745 MC roadster -- the lightest XK 140 -- and saw 0-60 mph in 8.4 seconds. That, it said, was “performance per dollar excelled by no other car . . .”
These were sports-car fellows and this was sports-car nirvana. There were things Detroit still didn’t seem to understand.
“The quality of finish is immediately apparent on the outside,” R&T said of its Jaguar, “but a look under the hood shows attention to detail that is in marked contrast to that found under a domestic product.”

Jaguar XK 150
Some say the XK 150 proves that Jaguar's first postwar sports cars hung on too long. They may be right, but the 150 was also the most thoroughly developed of the early XKs, if arguably the least sporting. This final variation on the original XK 120 theme was Jaguar's response to recently introduced rivals such as the BMW 507 and Mercedes-Benz 300SL, which bettered the XK 140 in catering to American demands for more comfort and refinement.

Jaguar's final XK 120 variation was the XK 150. It bowed in 1957 as a revamp of
the XK 140. Its styling was stodgier, it was heavier, and at first it had no more
power. But it was among the first cars with standard four-wheel disc brakes.
See more pictures of Jaguar sports cars.
Initially, the XK 150 was offered as a coupe and convertible. The roadster returned after nine months, but now with wind-up windows. Engine specs were the same as the 140, but the 150's extra weight prompted more buyers to pop for the 210-hp option, which now produced peak torque at 3000 rpm, not 4000. Not coincidentally, the extra-cost automatic transmission also garnered more orders, a sure sign of change in the sports-car world. 
Fewer buyers ordered manual transmission, but those who did could activate
overdrive with a floor lever rather than a dashboard toggle.
Though not the longest-lived, the 150 proved the most profitable of the original XK series. Tellingly, where roadsters had been the best-selling XK 120 and 140 body styles, the coupe was by far the most popular 150, accounting for 52 percent of sales. The roadster was the least popular, at just 13 percent. William Lyons had correctly read the evolving market and, with the XK 150's successor, he'd do it again.

Jaguar XK-SS
If the XK 120 rejuvenated Britain’s confidence, the LeMans winners it spawned restored the country’s spirit. Creating a “super sports” highway car from a LeMans victor was a fine idea -- or so it must have seemed. Jaguar tried it with the XK-SS, a high-performance roadster with roots in the world’s most prestigious sports-car race.![]() The XK-SS was one of those short-lived legends that make sports-car lore so rich. Jaguar built just 16 of a planned 100 before a factory fire destroyed its tooling. |
It won in 1951 and 1953 with the XK 120C (for “competition”). These were XK 120s with space-frame chassis, redesigned suspension, and aero bodywork. The fastest got 220 hp from the twincam 3.4 six and outbraked rivals on terrific four-wheel discs. Next came the lighter, slipperier D-type, a beautiful sports-racer that won in ’55, ’56, and ’57. With its 3.4 enlarged to 3.8 liters and 306 hp, the ’57 winner hit 179 mph.
![]() The XK-SS was a way of getting added value out of the retiring LeMans-winning D-type by modifying the race car just enough to make it suitable for road use. A competition-spec, triple-Weber 3.4-liter six was used, though racing cams concentrated power in the upper rev range. |
To wring some added value from the D-type at the end of its reign, Jaguar converted some into road-legal sports cars called the XK-SS. It shaved off the driver’s headrest fairing, widened the monocoque, added some upholstery, a passenger-side door, a folding top with detachable side screens, and flimsy little bumpers. The only place for a muffler was on the left rocker panel, and the only place for luggage was on a decklid rack. Retained was the 44-gallon rubber-cell racing fuel tank and the dry-sump competition 3.4-liter engine.
The XK-SS was ferociously fast, stopped on a sixpence, and had a remarkably comfortable ride. But it also was cramped and noisy, and the exhaust heated up the aluminum bodywork. Racing cams concentrated power in the upper rev range, making every drive an all-out affair. Reviews were mixed. Was the XK-SS too untamed to succeed? We’ll never know.
On February 12, 1957, three weeks after the car’s introduction, the part of the factory where it was built caught fire, destroying tooling, jigs, and partially completed cars. Jaguar was out of the super sports business, but the idea of a sports car built along D-type lines was worth pursuing. Jaguar would, and in the process create its most famous automobile.

Jaguar E-type
In the world of ’60s sports cars, this is where sex appeal came for lessons. Ferraris were provocative. Jaguar’s E-type -- XK-E in America -- was positively suggestive. An awed Road & Track subtitled its test report, “The greatest crumpet collector known to man.”![]() One of the most famous and recognized of all sports cars, the Jaguar E-type backed its libidinal lines with superior performance. |
Of course there was far more to it than libidinal lines. Its performance was predatory. Jaguar took the hot S-spec 3.8 from the XK 150 and moved the big inline-six rearward to redistribute weight 49/51. The new car was shorter and lighter than its predecessor, and added a vital component even the LeMans winners lacked: independent rear suspension.
Construction, too, improved on the racing D-type’s, with a monocoque (unitized) bodyshell in a choice of roadster or new hatchback coupe. Styling was by aerodynamicist Malcolm Saver, making this the first production Jaguar not shaped by William Lyons. Still, the founder’s hand was evident in the overall character of the car, as well as in its well-appointed, if cozy, cabin and in its reasonable price.
Jaguar unveiled its E-type in March 1961 at the same Geneva show that launched the XK 120 13 years before, and to the same frenzied reception.
![]() The Jaguar E-Type basically was a well-sorted production version of the LeMans-winning D-type racer, though with independent rear suspension. Jaguar’s grand 265-hp 3.8-liter six was mounted to provide a near-even weight balance. |
The E-type of 1965 got a displacement increase to 4.2 liters for better torque but no more horsepower. The following year brought a 2+2 coupe with a nine-inch-longer wheelbase, taller roofline, and optional automatic transmission. Styling of Series 2 models suffered in the late ’60s from side marker lights, clumsier bumpers, and upright exposed headlamps. But that hardly dulled their appeal. The E-type helped define the 1960s and to this day is one of the precious few sports cars to command the attention even of people who care little about automobiles.

Jaguar E-type Series 3 V-12
History repeated itself with the Jaguar E-type Series 3 V-12. It was a smashing success once, in 1948, when Jaguar debuted its robust new engine in a sports car instead of the sedan for which it was designed. But the inline-six that met its public in the XK 120 was 23 years old by 1971, and enfeebled by emissions regulations. The E-type was 10 years old and needed new life. Why not put the new passenger-car V-12 in a revised version of the aging sports model? Thus, the E-type Series 3 V-12 was born.
Its classic inline six enfeebled by emissions standards, Jaguar in 1971 turned
to V-12 power for the E-type. This created the Series 3, which came as a two-
seat convertible (shown) or a 2+2 coupe, both on the longer of two wheelbases
that had been offered on the six-cylinder E-types.
The new engine fit in the same bay as the six, but for better leg room Jaguar shelved the convertible’s 96-inch wheelbase and gave all Series 3s the 105-inch span previously exclusive to the 2+2 coupes. A larger radiator inlet with formal grillework and subtle wheel arches to clear wider tires were other changes. Larger, softer in nature, with weight redistributed 53/47, the E-type had lost the wilds of its youth.
![]() New safety rules mandated rocker switches on the Jaguar E-type Series 3 V-12's still-handsome dashboard. |
Jaguar had not duplicated its success of 1948, and it would be years before any of its sports models generated even a flicker of that excitement. Encounter a V-12 E-type, though, and see if you don’t study it long and hard.

Jaguar XJ220
Jaguar’s XJ220 appeared to have it all: a beautiful aluminum body, buyers queuing up with cash in hand, a 200-mph top speed. How then was it reduced to a fender-banging embarrassment in cable-TV exhibition races? And why did Jaguar end up suing some XJ220 customers?![]() The XJ220 had the potential to be a highly successful supercar, but ended up an embarrassment. It was very fast and very beautiful, but some customers who had put down their money far the exotic V-12 version refused delivery. |
The production XJ220 completed in June 1992 was a two-seat mid-engine coupe visually similar to the original. But it had a 542-hp 3.5-liter twin-turbo V-6, rear-wheel drive, and conventional steering and doors. It was quiet, comfortable, and very fast; even if it didn’t reach the 220-mph target that was the basis of its name, it confidently exceeded 210.
![]() Jaguar unveiled the mid-engine two-seater XJ220 in 1988 with a V-12, jackknife doors, and all-wheel drive and steering. When it went into production in 1992, circumstances had changed and the car had a twin-turbo V-6, rear drive, and conventional doors. |
To promote the car, Jaguar and the ESPN sports network cooked up Fast Masters, in which retired race drivers ran XJ220s at tiny Indianapolis Raceway Park. The long-legged exotics were out of their element. AutoWeek’s Denise McCluggage likened it to “racing thoroughbreds around the dining room table.” Much lovely aluminum was rearranged. On the open road, the XJ220 delivered. It was others who broke their promises.

Jaguar XK8
New Jaguars don't appear that often, so the 1996 arrival of the XK8 was a big event. Not only the first clean-sheet Jaguar since 1987’s “XJ40” sedans, it’s the first with a V-8 -- itself only the fourth major engine in Jaguar history. Moreover, this new coupe and convertible are the first XK Jaguars since the beloved E-type (a.k.a. XK-E) died 21 years before.![]() The XK8 puts Jaguar’s sports-car credentials in order for the first time since the E-type.It comes as a coupe and convertible and features Jaguar’s first V-8 engine. |
The XJS was hooted on its 1975 debut for abandoning sports-car basics as much as for its controversial coupe styling. But Jaguar knew what people wanted. With steady improvements to its big V-12, and the later addition of convertible and six-cylinder models, the S actually gained in annual sales as time passed.
![]() The XK8 mates beautifully with a new five-speed automatic transmission from Germany’s ZF that changes gears like a mercury switch. |
It was thus logical that the XK8 would follow a similar formula. The XK8 originated soon after Ford bought Jaguar in 1990 and axed an erstwhile E-type successor dubbed XK-F (some of which was later salvaged for the Aston Martin DB7).
Meanwhile, Jaguar was investigating V-8s and had a prototype engine running by late 1991. Two years after that, Ford approved a V-8 XJS replacement coded “X100,” and the XK8 was a showroom reality just 30 months later. That was warp-speed for tiny Jaguar, but the X100 team received valuable timesaving pointers from the Ford crew working on the new ’94 Mustang.
The result blends traditional Jaguar elegance with American manufacturing professionalism. XK8 not only is rock-solid and free of quirky details, it’s agile like the XJS never was. It’s fast, too, thanks to that muscular new “AJ-V8.” An all-Jaguar, all-alloy, twincam engine (what else from Coventry?), the AJ-V8 relishes revs, yet never rises above a muted growl. And it mates beautifully with a new five-speed automatic transmission from Germany’s ZF that changes gears like a mercury switch.
A pure sports car? No, the XK8 is far too refined for that, but it is a genuine sporting Jaguar and modern in every way. If that’s not something to celebrate, nothing is.
