Jaguar XK150 Fixed Head Coupé 1958 – Rally Prepared 3.8 Litre
There are classic Jaguars, and then there are Jaguars built to be truly driven. This 1958 Jaguar XK150 Fixed Head Coupé clearly belongs to the latter category. At first glance, it retains all the timeless elegance of a classic XK: the long bonnet, graceful coupé profile, imposing radiator grille and unmistakable British grand tourer character. Beneath that classic exterior, however, lies a highly considered rally-prepared car, developed for long-distance events and serious use.
The Jaguar XK150 was introduced in 1957 as the successor to the XK140 and represented the final evolution of the legendary XK line before the arrival of the E-Type. The XK150 was more modern, refined and comfortable than its predecessors, featuring a wider body, a one-piece curved windscreen and improved interior space. Initially available as a Fixed Head Coupé and Drop Head Coupé, the Open Two-Seater followed later. The 3.8-litre six-cylinder engine became available later in XK150 production, making this configuration especially desirable today among enthusiasts who want both style and performance.
This particular example, however, goes far beyond a standard XK150. It has been professionally modified with reliable, fast and comfortable rally use in mind. It is equipped with a powerful 3.8-litre six-cylinder engine, paired with a modern 5-speed gearbox, making it far smoother, more usable and more enjoyable to drive than a classic XK150 with its original transmission. On longer journeys, this makes a tremendous difference: lower engine speeds, better gear spacing and a far more relaxed driving experience.
Technically, this Jaguar has been thoroughly and expensively prepared. A special wiring loom has been installed, with each circuit individually fused and operated through separate relays. This is not only safer, but also far more reliable and easier to service during intensive use or rally participation. The car is further equipped with a roll cage, special rally seats, Tripmaster, adjustable power steering, automatic choke, electric cooling fan, Webasto heating and a dry-sump engine system. These are not superficial upgrades, but carefully chosen modifications that make it clear this XK150 was built with real rally use in mind.
The result is an exceptional combination: the charm, class and presence of a 1950s Jaguar, combined with usability much closer to that of a modern car. Whereas a standard XK150 often requires adaptation, concentration and mechanical sympathy, this car feels far more accessible, secure and efficient. The adjustable power steering, 5-speed gearbox, improved cooling, upgraded electrical system and rally instrumentation make it particularly well suited to long-distance driving, regularity events and international classic rallies.
It is important to note that this conversion has been professionally executed. Modifications of this level require not only extensive technical knowledge, but also represent a very significant investment. The quality of the build and the choice of components clearly show that this car was intended to perform reliably, not merely to look impressive in a collection.
This Jaguar XK150 Fixed Head Coupé is therefore absolutely not comparable to a standard classic XK150. It retains the iconic looks and character of the original, while offering a level of driving ease, reliability and control that greatly enhances the enjoyment behind the wheel. For anyone dreaming of taking part in long-distance rallies in style, or looking for a classic Jaguar that can genuinely be driven and enjoyed, this is a particularly attractive and rare opportunity.
An impressive gentleman’s rally car: elegant, powerful, professionally prepared and ready to cover great distances once again — exactly what a true grand tourer was always meant to do.
