The Jaguar XK140 is a sports car manufactured by Jaguar between 1954 and 1957. It was the XK120's replacement and came in the roadster, coupe, and drophead coupe body types. The car was designated XK140 SE in the UK and XK140 MC in North America.
The "M" or "Special Equipment" package, which was part of the MC option, came with a crankshaft dampener, a dual exhaust system, wire wheels, and more power.
The 3.4-liter Jaguar XK double overhead camshaft inline-6 engine, which William Heynes designed, provided power for the XK140. The XK120 Special Equipment upgrades increased the specified output by 10 bhp to 190 bhp (142 kW) gross at 5500 rpm as standard
More interior room, better brakes, rack and pinion steering, longer suspension travel, and telescopic shock absorbers in place of the previous lever arm design were among the improvements. Among all British sports vehicles ever made, the Jaguar XK120, XK140, and XK150 are three of the most recognizable models.
The XK140 had a number of significant differences from its forerunner, the XK120. The vehicle had a larger interior and was broader and longer than the XK120. The grille was more upright, and the front bumpers were modified from being two separate parts to one single item.
Along with better brakes, rack and pinion steering, longer suspension travel, and telescopic shock absorbers in place of the previous lever arm design, the XK140 also included these features.
