Due to the many technical innovations, which have been gained in motorsport but also from the experience with the previous model, it is time to bring a successor model to the market after six successful years of production. 1954 at the London Motor Show on Earls Court, it is time again, Jaguar presents the XK140. The result surprises only a few, what one wants to change in terms of appearance, especially the optics were already part of the success concept with the predecessor. With the chassis and the body, everything with its elegantly curved sideline stays the same. The export, especially to America, continues even after 6 years and so one corresponds to the customer's desire for more Chrome, which is very popular in the 50's. It comes with large, one-piece bumpers, trims and only 7 wide, instead of the 13 narrow longitudinal struts in the radiator grille. In the future, a Jaguar emblem will be emblazoned on the trunk, reminiscent of the victories at Le Mans. Even today, many years later, it will be said that this decision was a great admission to the market. Due to the further development of the engine, driven by commitment in motorsport, the driver is now pleased with 190 horsepower. The sport version (SE version) is equipped with the new cylinder heads of the XK120C short C-Type, which increases the horsepower to 210. The removal of the battery and the installation of the engine block by 76mm forward provides additional space in the interior. Thanks to the won space, a Laycock de Normanville Overdrive is now also available, as well as a three-speed automatic transmission from the company Borg-Warner for coupé and convertible from October 1956. The model variants remain unchanged. There is also an "Open Two Seater" (Roadster), a "Fixed Head Coupé", as well as a "Drop Head Coupé" (Cabrio). The production time of the XK140 will take just over two and a half years.

The Roadster, produced from October 1954, sells very well, especially in the USA, and is more popular there than its sister models. In contrast to the motherland, for which only 73 right-hand-drive roads are built, of which only 47 remain in the Kingdom of Great Britain. Maginal but strikingly beautiful: for the domestic market, the spoke wheels are often painted in the colour of the car body. Unlike the coupé and convertible, the additional space gained is not extended by two emergency seats in the rear area, it is good for the foot space. The roadster remains a pure two-seater.

construction time, prices, production figures and vehicle numbers
From October 1954 to February 1957, 3354 vehicles were built. A total of 73 right-hand-drive (RHD) vehicles and 3281 left-hand-drive (LHD) vehicles will be produced by the end of production. The base price in the United Kingdom is £ 1127.-.
The body numbers do not distinguish between left or right-hand-steered vehicles, they are numbered consecutively and start with F10001.
The chassis numbers consist of 6 digit number combinations and differ in those for vehicles with right-hand drive (RHD) starting with the number 800xxx and for vehicles with left-hand drive (LHD) starting with the number 810xxx. Certain chassis numbers have additional letter designations before and after the number combination. These have the following meaning:Chassis numbers with a leading "A" stand for vehicles of the "Special Equipment" versions, referred to in America as XK140 M.Chassis numbers with a leading "S" stand for vehicles of the "Special Equipment" versions, with C-Type cylinder heads, referred to in America as the XK140 MC.Chassis numbers with a trailing "DN" stand for vehicles with built-in "overdrive"."

Some of the first Jaguar XK140 stake still uses engines from the XK120 production. In total, it is a Jaguar XK140 OTS (LHD) whose engine starts with the letter "F". According to research in the Jaguar archives, the last engine probably bears the number G9980. The addition -8 or -9 after the number describes the compression ratio of the engine. An additional "S" directly behind the compression ratio is available for C-Type cylinder heads ex works. -

The coupé comes on the market at the same time as the Roadster and the Drop Head Coupé and undergoes the most major changes. Due to the magnification of the interior, it is equipped with larger side and larger rear window, for better all-round visibility. In order to achieve the magnification, the spray wall, which now encloses the rear part of the engine, and the A-pillar with window front is moved forward. The bonnet is shortened somewhat according to the total length. In the rear, two emergency seats are created, which makes it a 2+2 seater and more space in the footwell.

The Drop Head Coupé is by no means just a modified XK140 coupé with top, although it also has two emergency seats, while the XK120 Drop Head Coupé was a pure two-seater. Unlike the XK140 Coupé, the space for this is not created by changes to the spray wall, A-pillar and windshield, but only by the general installation of the engine block and a reduction in the trunk. The proportions of the doors and the top remain almost identical to the previous model. Only in the case of the convertible is the two 6 volt batteries behind the seats, a 12 volt block in the engine compartment.
