Features
While the XK120 had a new overhead-camshaft XK engine, the Mark V retained the 1946-48 driveline including the overhead-valve pushrod straight-6 2½L and 3½L engines, now since 1946 produced by Jaguar, which the company had purchased from the Standard Motor Company before the Second World War and the four-speed single-helical gearbox produced by both Jaguar and the Moss Gear Company of Birmingham. Automatic transmission was not available at this time. The 1½L Standard engine used in previous models was not offered in the Mark V. Claimed power output in this application was 102 bhp[1] for the 2664 cc Mark V and 125 bhp for its more popular 3485 cc sibling.[1][8]
The chassis frame was new with deep box sections and cross bracing for improved stiffness in handling and cornering, and independent front suspension by double wishbones and torsion bars, an arrangement that would be used by Jaguar for many future vehicles. It has weldments and brackets provided for both Left Hand and Right Hand Drive brake and clutch pedal linkages, so the chassis could be assembled in either configuration. It also had hydraulic brakes, which were necessary with the independent suspension, and which Jaguar had been slow to adopt compared to other manufacturers, and an all pressed steel body on the saloon, though the DHC still had wood framing in the doors. Another new feature was that the rear of the chassis swept over the rear axle to provide greater movement for improved comfort, whereas on previous models it had been underslung.[9]
The styling of the car followed prewar SS-Jaguar lines with upright chrome grille and the leaping Jaguar radiator cap mascot was available as an option. The Autocar called it rich yet with unostentatious looks, in outline halfway between the old and new.[10] There is a distinct hint of the recently modernised Bentley look in the style of the front grill.[8] The wheels were 16 in steel-disc type, significantly smaller than the 18 in wheels on the MK IV. From the side, a distinctive styling touch on the saloon was a "tuck in" curve at the base of the rear quarter window following the curved profile of the side glass, a feature retained on many subsequent models. Rear-wheel spats were standard. There was also a drophead coupé version.
For the UK and most foreign markets, 7.7" Lucas PF770 headlamps were used, along with flip-out trafficator semaphore turn indicators. For the important American market, 7" sealed headlights were used, along with flashing turn signals incorporated into the front side lamp and rear tail lamp units in place of trafficators.[11][12]
The Mark V was available in 12 single paint colours, in various combinations with 7 upholstery colours, but the factory did not offer two-tone treatment, nor did they offer white wall tyres. Two cars were done by the factory in two-tone schemes, and 32 others in various special colours, for unknown reasons. Others may have been repainted as two-tone by American dealers before or after the sale, as well as fitting white wall tyres.[13]
