TYPES

In this area, you can learn a lot about the legendary production vehicles of the Jaguar XK series, from the Jaguar XK120 to the Series 3 of the Jaguar E-Type.

We are writing the year 1948, the war has been over for three years. One of the biggest car fairs of the post-war era, the London Motor Show on Earls Court is about to reopen. The show is scheduled for October 27. The Jaguar car manufacturer faces a dilemma. The newly developed 6 cylinder in-line engine XK as well as the chassis have been completed in time, but the body, which is manufactured by the company Pressed Steel, is missing. These three main components are part of a newly developed and fast travel limousine, the Mark VII. Jaguar expects a better deal from the limousine division and wants to introduce the new car at the Motor Show. As it becomes increasingly apparent that the timetable cannot be kept, an emergency solution is being found. Sir William Lyons, founder and master of Jaguar Cars Ltd., has the finished chassis of the MK VII shortened by 18 inches in order to achieve the right wheel distance for a sports car. He designs a matching, elegant open two-seater body on his own. Together with Fred Gardner, his man for practical implementation, he converts this into reality in Foleshill at the back of his work. The venture is only frighteningly short before the fair. This emergency solution will be produced in a small edition of about 200 vehicles to serve potential customers of the London Motor Show and to bridge the time for the introduction of the new MK VII. As you know, however, things are always different from what you think. The new Roadster strikes like a bomb and the orders are so numerous that it more than doubles the target number, not least because of the good price-performance ratio. It was then decided to produce the roadster in series. The Jaguar XK120 was born.

Jaguar XK120 OTS

The Roadster goes into production in July 1949, initially with an aluminium body, as the "Jaguar XK120 OTS". The "XK" stands for the type designation of the engine (X-Experimental/K series), the number "120" for the maximum speed, a tradition started before the war. Last but not least, the term "OTS", which stands for "Open Two Seater". For later vehicles, there are often additional optional designations behind the speed designation, such as "SE" for "Special Equipment" or "M" for "Modified", the designation for "Special Equipment" on export vehicles to the USA.

  • construction time, prices, production figures and vehicle numbers

    From July 1949 to September 1954, 7611 vehicles were built, of which the first 240 vehicles are equipped with aluminium bodies, as this raw material is available after the war. Between April and May 1950, the production of aluminium to all-steel body with aluminium doors and hoods was changed. A total of 1173 right-hand-drive (RHD) vehicles and 6438 left-hand-drive (LHD) vehicles will be produced by the end of production. The base price in the United Kingdom is £ 998.-.
    The body numbers do not distinguish between left or right-hand-steered vehicles, they are numbered and start with F1001.
    The chassis numbers consist of 6 digit number combinations and differ in those for vehicles with right-hand drive (RHD), starting with the number 660xxx and for vehicles with left-hand steering (LHD). starting with the number 670xxx. Certain chassis numbers have additional letter designations before and after the number combination. These have the following meanings:

    The engine numbers are not listed here, as they are not only used in OTS models, but in all Jaguar XK120 types, depending on the order. They start with W1001 and end with W9999.

According to research in the Jaguar archives, the last engine probably bears the number F4249. The addition -7 or -8 after the number describes the compression ratio of the motor.

Jaguar XK120 FHC

In March 1951, almost two and a half years after the first presentation of the Roadster, a closed travel coupe was presented at the Motor Show in Geneva, which is called FHC (Fixed Head Coupé) ex works. The curved shape of the roof is considered very successful and bears some resemblance to the earlier design of the Jaguar SS100 3.5-litre Coupé, which never went into production. The interior was comfortable and luxurious. In addition to a dashboard made of decorative walnut and wool carpets on the floor, there is even a heating system inside, which the roadster has always lacked.

Jaguar XK120 DHC

Another year later in April 1953, the convertible, commonly known as the Drop Head Coupé (DHC), finally came out. It has all the amenities of the coupé and has an easy-to-use, lined mohair folding top. The vehicle is an ideal compromise between the coupé and the roadster. Due to the late introduction of the DHC variant, it is on the one hand the most mature model and on the other hand, the one with the lowest production number. Most convertibles, like the roadsters and coupés, are sold on the North American market.
