The Jaguar E-Type is the successor car to the XK 150.

It was at the London Motor Show in October 1964 that the new 4.2-litre group appeared.

It is inside that the novelties will appear, with the disappearance of the bucket seats in favor of ribbed armchairs whose inclination is adjustable. The aluminum of the center console is replaced by leather.

On the outside, nothing distinguishes a 3.8 from a 4.2 liter, except for the 4.2 liter logo on the rear hatch.

In November 1965, modification of the rear hatch opening system: double scissor stand with automatic positioning to replace the previous straight rod. In March 1966, Dunlop SP 185 HR 15 tires were fitted together with a rack giving more direct steering. In September 1966, the instrument panel dials received green lighting instead of blue and sun visors became standard on the convertible.
