Jaguar launched its first small unitary construction saloon, the 2.4 Litre, in 1955. The new model was Jaguars first "small" saloon since the demise of the old 1.5 Litre cars in 1949. Jaguar aimed the new car at the developing executive market and thanks to its keen pricing soon found itself swamped with orders.
The body of the 2.4 Litre (NB: the "Mk I" title was used retrospectively from 1959) featured heavy door window surrounds and looked bulbous compared to many other luxury saloons of the era. The cars 2483cc twin overhead cam engine provided enough performance (over 100mph) for the day and came with optional overdrive and automatic transmission.
For many years the Mk I 2.4 model has lived in the shadow of the more romantic Mk II, however these cars are now rare and are becoming more sought after.
