Designed by well known aerodynamicist Malcolm Sayer the car was aerodynamically advanced and drop-dead gorgeous, built around a monocoque (chassisless) shell with front frames to hold the suspension and engine and an advanced rear independent suspension that would end up being used by all subsequent saloons of the period. Initially fitted with the 3.8 litre version of the legendary XK engine with triple carburettors and high compression head, the car capable of up to 150mph in standard trim, yet was very practical in town driving conditions.

Available as a two-seater roadster or a fixed head coupe with rear opening ‘hatch’ door for luggage, the car was upgraded in 1964 with the 4.2 litre engine, all synchromesh gearbox and improved seating. In 1966 an extra model, with 2 + 2 seating capacity was introduced by increasing the wheelbase by 9 inches and raising the roof by 2 inches. This also enabled the car to be fitted with the option of automatic transmission.

Due to changes in legislation in the USA, the E-type had to go through various changes which started with the substitution of the flared in headlights for an open type and some changes to switch gear in the car along with emissions systems for the engine. Interim changed cars were still identified as Series 1 models, but have later become known as Series 1 1/2 because there was no clear differentiation between the earlier and later Series 2 models in specification.
