1955 Jaguar XK140 Image
from Classic to Modern
The XK140 Jaguar sports car was, in essence, a further development of the XK120.
Launched at the London Motor Show in 1954, it introduced a number of refinements to improve driveability. These included:
The more powerful engine and stronger torsion bars preciously fitted to the XK120SE variant then became standard equipment on the XK140 sports car.
The engine and bulkhead were moved three inches further forward in order to create sufficient additional space to fit a small occasional rear seat, something that was absent in the convertible variant.
In terms of external appearance, the only change from the "120" was the addition of heavier bumpers and over riders, as used in the Mark 7 saloon, plus flashing indicators, which were activated from a switch on the dashboard, and were positioned above the rear bumper.
In the centre of the boot lid there was a red emblem, presented in gold, commemorating "Winner of Le Mans 1951-3".
Other changes in respect of the XK120 included:
Following on from the "120", the fixed head and drop head variants also had the dashboard and internal door coverings finished in walnut, whilst the equivalent in the convertible were finished in leather. Jaguar cars performance:

As with the XK120, there were three body styles available:
The XK140 Jaguar sports was powered by a 3.4 litre, straight 6-cylinder, twin overhead cam, XK engine fitted with two H6 SU carburettors, which developed 190 bhp at 5500 rpm, and 203 ft/lbs of torque at 3000 rpm.
The was also a higher performance XK140SE variant, using the same engine, but fitted with two larger H8 SU carburettors and a "C" type aluminium head, which developed 210 bhp at 5750 rpm, and 213 ft/lbs of torque at 4000 rpm.
All three variants featured:
The SE variant was also fitted with wire wheels, fog lights, overdrive, and an uprated exhaust system.
When production ended in 1957, the output for each variant was: Convertible = 3350, Fixed Head Coupe = 2800, Drop Head Coupe = 2793
This model was a further evolution in the range of Jaguar cars.
A 1954-57 Jaguar XK140 in very good condition would fetch in the region of £75,000/$120,000 to £90,000/$145,000, whilst a really superb example would command around £120,000/$200,000.
