2017 Jaguar XKSS

Jump to Images

The Jaguar D-Type was one of the most sensationally successful race cars of the 1950s. Built from 1954-1957, the D-Type in its last year of production not only won Le Mans, but took 5 of the top 6 places. Although the D-Type was an inspiration behind the famous E-Type of the 1960s (note the E-Type following the D-Type), the actual roadgoing version of this car was the XKSS built in 1957. Jaguar originally planned to build 25 cars, but a fire at the Browns Lane plant on February 12, 1957 destroyed 9 of the cars, so only 16 were produced, most being sold in the United States.

Jaguar has decided to complete those 9 missing cars 60 years later, and has painstakingly constructed these beautiful cars to their original specs. The cars will feature magnesium alloy bodies, like the original, and will be formed on new but historically accurate bucks by hand-wheeling.

The cars are powered by a 3.4 liter inline-6 putting out 262 hp and breathing through 3 Weber carburetors. All mechanical differences between these last 9 cars and the originals from 1957 are minimal, related to safety, and invisible to the occupants. For example, the fuel cell uses stable modern materials to handle the fuels we would use today.

Every new XKSS will have 10,000 man hours invested. Final price is said to be north of £1 million, and it's not surprising that all of them have already been sold.

(from Jaguar Press Release) The ‘New Original’: Jaguar XKSS makes World Debut in Los Angeles

  • Jaguar Classic reveals ‘new original’ XKSS to media at Petersen Museum in Los Angeles
  • One-off car has been authentically produced to exact 1957 specification by Jaguar Land Rover Classic’s expert craftsmen
  • Nine examples to be hand-built in the UK with deliveries to customers beginning in 2017
  • New film captures XKSS driven for the first time in Los Angeles by Jaguar Classic Engineering Manager Kev Riches

The stunning XKSS, finished in Sherwood Green paint, has been created by the Jaguar Classic engineering team ahead of the production of nine cars for delivery to customers across the globe in 2017.

Often referred to as the world’s first supercar, the XKSS was originally made by Jaguar as a road-going conversion of the Le Mans-winning D-type, which was built from 1954-1956. In 1957, nine cars earmarked for export to North America were lost in a fire at Jaguar’s Browns Lane factory in the British Midlands; meaning just 16 examples of XKSS were built.

Earlier this year Jaguar announced that its Classic division would build the nine ‘lost’ XKSS sports cars for a select group of established collectors and customers. The new one-off XKSS presented in Los Angeles is the summation of 18 months of research and will be used as a blueprint from which the nine continuation cars are built.

The nine cars will be completely new, with period chassis numbers from the XKSS chassis log. All cars are now sold at a price in excess of £1million each.

The XKSS is the second continuation car to be created by Jaguar, following on from the six Lightweight E-types that were built in 2014. This project helped the team learn to engineer cars that are faithful to the specifications to which they were built in period, and this knowledge has been enhanced in creating the ‘new original’ XKSS.

The XKSS unveiled in Los Angeles is a period correct continuation, built using a combination of original drawings from Jaguar’s archive and modern technology. The Jaguar Classic engineering team scanned several versions of the 1957 XKSS to help build a complete digital image of the car, from the body to chassis, and including all parts required.

The body of the XKSS is made from magnesium alloy, as it was in 1957, and because the original styling bucks do not exist, Jaguar Classic produced a new, bespoke styling buck based on the original bodies from the 1950s. The bodies of the nine new cars will be formed on this buck, using a traditional process called hand-wheeling.

Jaguar Classic’s expert engineers worked with the original frames and from there produced CAD to support build of the chassis. In partnership with the Classic team, frame maker Reynolds – famous for their 531 tubing – was briefed to craft bespoke new parts using imperial measurements, rather than metric. The frames are bronze welded in the same way as the period XKSS chassis tubing. The continuation cars feature period specification four-wheel Dunlop disc brakes with a Plessey pump, and Dunlop tyres with riveted two-piece magnesium alloy wheels.

Under the bonnet, the XKSS is supplied with a 262hp 3.4-litre straight six-cylinder Jaguar D-type engine. The engine features completely new cast iron blocks, new cast cylinder heads and three Weber DC03 carburetors.

Inside, the ‘new original’ XKSS features perfect recreations of the original Smiths gauges. Everything from the wood of the steering wheel, to the grain of the leather seats, through to the brass knobs on the XKSS dashboard, is precisely as it would have been in 1957.

Minor specification changes have been made only to improve driver and passenger safety. The fuel cell, for example, uses robust, modern materials to support throughput of modern fuels.

Customer vehicles will be hand-built beginning this year, and it is estimated that 10,000 man hours will go into building each of the new XKSS cars.

The XKSS is one of the most important cars in Jaguar’s history, and we are committed to making the ‘new original’ version absolutely faithful to the period car in every way. From the number, type and position of all the rivets used – there are more than 2,000 in total – to the Smiths gauges on the dashboard, everything is the same as the original cars, because that is the way it should be.
