The 1963-1969 Jaguar S-Type/420 were literal extensions of Jaguar's original Mark II sedan series first seen in 1956. The S-Type, introduced for 1963, featured a longer, Mark X-like tail grafted onto the original unitized body/chassis structure. To go with it, Jaguar added a coil-spring independent rear suspension similar to that of the E-Type.

In 1967, to provide even closer family resemblance with the Mark X, which was renamed 420G that year, Jaguar announced the 420. This was an S-Type with a squared-up Mark X nose including a square grille and four headlamps. By this time, there was little of the original 2.4-liter Mark II left.

All these models carried the by-now familiar twincam XK engine, with model designation reflecting displacement (3.4S, 3.8S, 420). Typical Jaguar interior appointments were featured, and both manual and automatic transmissions were available. Each version was slightly heavier and less nimble than the one before it. The 420 was capable of 125 mph, and was also sold in England as the badge-engineered Daimler Sovereign with a traditional fluted grille and different trim details.

This series can be considered the direct predecessor of the sterling XJ6, which arrived for the 1969 model year.
