Mk X, 420G

The Jaguar Mk X and its later evolution, the 420G, were produced between 1961 and 1970 as Jaguar’s flagship luxury saloons. Featuring bold, wide-body styling and an opulent interior, these grand tourers were powered by the smooth and potent 3.8 or 4.2-litre straight-six engines. Designed to deliver limousine-like comfort with sports car-inspired handling, the Mk X and 420G offered advanced features such as independent rear suspension and power-assisted steering. These imposing saloons reflected Jaguar’s ambition to rival the best from Rolls-Royce and Mercedes-Benz, combining presence, performance, and prestige.
