Road testing a left-hand-drive XKSS is a first, not only for this writer, but for the entire Jaguar community worldwide, as all the 16 original Jaguar XKSSs built in 1957, and all seven Lynx hand-crafted reproductions constructed since, came out of their respective factories in right-hand-drive form.The only left-hooker in existence appears before our eyes, as if a mirror-image of perfection, and this is the story of how such a unique XKSS came about.The clien t - In recent years, Lynx has found its comprehensive website to be an efficient tool to prime prospective clients on what is available. "It is an effective way of taking Lynx to our prospective customers," said Lynx proprietor John Mayston-Taylor.In this case, the client is a computer consultant who designs web cafes in the Czech Republic. Young, but very knowledgeable, this car enthusiast was after a really special car that he would relish driving, but that would also not attract attention like a new Ferrari. "We are seeing a new generation of customer in their 30s, who do not remember the 1950s cars when they were new, but yearn for the simplicity and directness of such cars," said John. "The feeling of freedom, the good power-to-weight ratio and less traction from skinny tyres are all part and parcel of the appeal of a car that you have to drive." By the time the customer visited Lynx, not only had he set his heart on an XKSS, he had done his research very well indeed, which helped Lynx immensely too. It was clear that he fully understood how and why Lynx do certain things to achieve its legendary high standards, and he appreciated why some things cost as much as they do. "Acknowledging that we had never built a LHD XKSS before, he was willing to be the first and to pay for the extra work this would entail," said John.
Having seen more than one original XKSS, it's fair to say that in terms of detail finish a Lynx reproduction improves on the quality of the 1950s original, which was, after all, based on a raw racing machine. In fact, in those respects, as well as the resulting driving experience. Lynx cars always feel more like the original would have, had it been developed for longer. A 1950s design built with present day knowledge, expertise and precision is a fair way to sum up a Lynx reproduction. While the Lynx XKSS (and D-type) recreations gain sophistication in ride and handling by using the E-type independent rear suspension, the body construction process for the Lynx XKSS is very much as per the original Jaguar factory car. Bearing in mind that the XKSS was the road-going version of a Le Mans winning racer, the entire bodyshell is made from aluminium. It comprises a central monocoque with the front and rear sections welded or riveted together to form the various body units that attach to that central monocoque. The front chassis frames are new and are fabricated from rectangular steel tubing and bolted to the front bulkhead of the monocoque. The later Jaguar E-type continued to use this method of construction, albeit with a steel body. However, the tubing Lynx uses has 25% more torsional rigidity than the original E-type, which used Reynolds steel tubing. The body panels that give the XKSS its curvaceous lines have incredibly complex compound curves that have to be hand-formed from flat sheets of aluminium. This difficult task and labour intensive process is done using an English Wheel, a unique device that a skilled operator uses to shape the metal to exactly cover the contours of the wooden body bucks. Designing and fabricating the LHD conversion added nearly four weeks to the car's build, but the process was substantially easier than converting an existing RHD car. The work was made simpler by the fact that the engineers were starting with a clean sheet of aluminium, so to speak. However, the task was not quite as straightforward as mirror imaging the RHD car. For instance, the passenger side footbox is shorter than the driver's side, and the exhaust system had to be re-routed to suit the modified floorpan. Understanding the complexities involved helps you appreciate what it takes for a major European manufacturer to create a RHD version of a car and is something best done at the development stage.
Increased power - An XKSS, especially the Lynx version with its hand-built engine, is not a slow car, but the customer wanted more power, and especially torque. Applying all its experience to the power unit, the engine shop started out with a stock Jaguar 4.2-litre block from the E-type donor car. This was thoroughly inspected, crack detected and strengthened before work began to enlarge its bore and stroke to 92.58 x 112mm for a swept capacity of 4,524cc. The block was then fitted with a new fully-balanced, forged steel crankshaft, new lightweight steel competition connecting rods and forged pistons. The reciprocating parts were individually weighed to within one-gram tolerance. some again as a set, and then also balanced as required.
The compression ratio is a relatively modest 8.785:1 to cope with possible poor fuel quality. With gas-flowed heads and those triple Weber 45 DCOEs, the big XK motor produces 320bhp at 5,400rpm with 350lb ft of torque at 3,800rpm.
Because the XKSS is a small car with light and communicative steering, positioning on the road is not a problem. The foot controls are also nicely weighted and progressive and, in common with all cars of this era, the carburettored engine has a crispness missing from modem power units, especially those with a single throttle body feeding a big intake plenum. The extra torque from the 4.5-litre motor produces spectacular results in such a light car, and this means that the gearlever need only be used a lot either for the pleasure of doing so, or when really in a hurry. The tall, skinny tyres also mean that when the significant torque of this big motor is deployed, the driver had better be prepared to use the steering to contain the resulting slides.
A car that has been put together so lovingly by one person for another is more than just a driving machine. "As with many of our clients, the project is the pleasure," John explained. "The process of choosing the specification and watching a car being built just for you has an appeal for some people that goes beyond simple ownership once it is finished. For some, the experience is like watching your child grow in its mother's womb. Fittingly, this car took almost exactly nine months to build."
True, that sounds like an awful lot of money, but if you want a really unique sportscar that gives you a level of driver feedback, even at normal road speeds, that exceeds that of any modern supercar, then a Lynx XKSS or D-type recreation may just be the car for you. |
