The first genuine Jaguar XKSS to be built in almost 60 years was given its world debut presentation at the Petersen Museum, Los Angeles by Jaguar Classic. 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Often referred to as the world’s first supercar, the XKSS was originally made by Jaguar as a road-going conversion of the Le Mans-winning D-type, which was built from 1954-1956.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.
In 2016 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 £1 million each.
The Jaguar 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 body of the Jaguar 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 Jaguar 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’ Jaguar 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 in 2016, and it is estimated that 10,000 man hours will go into building each of the new XKSS cars.
