In Britain’s late-1970s automotive scene, Jaguar balanced traditional luxury with a taste for sportier silhouettes, making 1977 a notable year for collectors and enthusiasts alike. These models turn up at shows and on country roads, offering a clear window into the marque’s approach to comfort, engineering and style at that time.
There are 12 1977 Jaguar Car Models, ranging from the Daimler Double-Six to the Jaguar XJ6C. For each model I list Body style, Engine (L), Production (units) so you can compare design, power and rarity quickly; you’ll find those details below.
How do the 1977 Jaguars differ in engine size and body style?
The 1977 lineup covers sedans, coupes and long-wheelbase luxury variants, with powerplants running from straight-sixes up to V12s, so performance, weight and fuel consumption vary significantly between models; check the Body style, Engine (L), Production (units) columns below to see where each car sits.
Are parts and maintenance for these 1977 models hard to source?
Common mechanical parts remain available through specialist suppliers and aftermarket channels, but rare trim pieces, specific electrical components or certain body panels can be scarce—joining a Jaguar club or working with experienced restorers usually makes sourcing and maintenance much easier and more cost-effective.

Images and Descriptions
Jaguar XJ6 4.2
The heart of Jaguar’s lineup, this long-wheelbase sedan was the brand’s bestseller worldwide. It offered a legendary smooth ride and classic styling, though US-market cars received larger, less elegant safety bumpers required by federal regulations.
Jaguar XJ6 3.4
A more economical version of the XJ6, the 3.4-litre model was primarily sold in the UK and Europe. It provided the same luxury appointments and elegant looks as the 4.2L but appealed to buyers concerned with fuel costs and taxation.
Jaguar XJ12
As one of the world’s only V12-powered sedans, the XJ12 was the flagship performance model. It delivered silent, effortless power and immense refinement, cementing its status as a super-saloon that competed with the most expensive European luxury cars.
Jaguar XJ-S
A grand tourer designed for high-speed cruising, the XJ-S featured a powerful V12 and futuristic styling with distinctive ‘flying buttress’ rear pillars. By 1977, the manual gearbox was gone, making the smooth GM automatic transmission standard on all models.
Jaguar XJ6C
1977 marked the final year for this beautiful pillarless coupe. Based on the XJ’s short-wheelbase platform, the XJ6C combined the sedan’s reliable inline-six engine with a sleek two-door body, always featuring a standard vinyl roof to cover panel seams.
Jaguar XJ12C
Pairing the elegant pillarless coupe body with the formidable 5.3L V12 engine made the XJ12C a true “brute in a suit.” As production ceased in late 1977, its combination of stunning looks and massive power makes it exceptionally rare and desirable today.
Daimler Sovereign 4.2
The Daimler-badged version of the XJ6, the Sovereign, was distinguished by its traditional fluted grille and more opulent interior. It was marketed to a more conservative clientele who desired Jaguar’s engineering with a different, stately image.
Daimler Sovereign 3.4
Offered in the UK and Europe, this model provided the prestigious Daimler badge and luxurious trim with the more fuel-efficient 3.4-litre engine. It was an attractive option for executives and officials seeking classic British luxury with lower running costs.
Daimler Double-Six
The ultimate Daimler sedan, the Double-Six was the counterpart to the Jaguar XJ12. It combined the silent, potent V12 engine with the highest level of standard Daimler luxury, making it an exclusive and opulent flagship model for discerning customers.
Daimler Double-Six Vanden Plas
The absolute pinnacle of the range, these cars were hand-finished at the Vanden Plas coachworks in London. They featured a bespoke leather interior, Wilton carpets, rear picnic tables, and unique colour schemes, representing the ultimate in British Leyland luxury.
Daimler Sovereign Coupe
A rare and distinguished pillarless coupe, this model featured Daimler’s signature fluted grille and upmarket interior on the beautiful XJC body. Its production run ended in 1977, securing its status as a desirable and collectible classic for Daimler enthusiasts.
Daimler Double-Six Coupe
The rarest production model in the 1977 lineup. This car combined the most exclusive Daimler badge, the powerful V12 engine, and the elegant two-door pillarless coupe body. With very few ever made, it is the ultimate collector’s version of the XJ coupe.
