Jaguar was working on the next generation of models as far back as May 1967, one of which was a new two-plus-two seater E-type, code name XJ21. At this point that the design team realised a totally new image was required to entice customers back to buying Jaguars and this meant producing a car that would surpass all expectations. Therefore, the XJ21 was dropped from the potential production line-up and the company’s efforts were re-directed towards the alternative design.
The designers looked at a variety of modifications that were broken down into four stages and these were:
Stage 1 – modifications were made to the bonnet, front wings and to the widening of the front and rear wheel tracks
Stage 2 – modifications were made to the bonnet, wings, raised scuttle and doors on the body. The chassis frame was widened to take the planned 3.4 litre V8 or the 5.3 litre V12 engine with a five-speed manual gearbox or alternatively, the Model 8 Borg Warner automatic gearbox
Stages 1 and 2 were already in the hands of Malcolm Sayer, looking for the next distinctive model that would generate sales for the company.
Stage 3 – a complete re-styled E-type utilising the current floor structure, suspension, front and rear axles
Stage 4 – an E-type replacement that was based around the XJ saloon chassis
It was felt that the stage 4 modification would not necessarily satisfy the E-type customer base either in relation to the weight or size.
