MK 1

From 1955 to 1959

Based on a unitary (chassisless) construction and with similar styling to the other models, the XK engine was produced in a smaller 2.4 litre capacity for the new model, announced for the 1956 model year as the 2.4 litre saloon. Initially with drum brakes, by 1957 a larger 3.4 litre engined version became available with subtle styling changes and disc brakes became a standard fit. The cars stayed in production until 1959.

Cadwell Park Adam Powderham Pursues The Mid Field Pack

This 2.2 mile Parkland circuit is wonderful when dry but in the wet, with a grid full of Jaguars? A totally different story. Arriving on Friday for free practice, it was pouring & extremely slippery.

There can be no nicer circuit than Oulton Park on a warm sunny day & that's what we woke up to. This was the final round of the championship with so much to win (or lose) for both class points & the overall championship.
