This belief stems from Callum's first sighting of the original XJ6 saloon in the 1960s, an event he describes as "the moment the penny dropped" when it came to his understanding of car design.
The show car rides on 21-inch alloy wheels with custom-made Pirelli tyres, which sit below heavily flared wheel arches. The grille is an indicator for the look of future Jaguars and draws its inspiration from the E-type.
Rising from the radiator grille, a prominent bulge in the bonnet runs to the base of the windscreen to invoke an impression of power.
From there the cabin flows back in a clean line to the car's rear end which tapers sharply to a focal point of two, centrallymounted tailpipes.
There is also an opening tailgate, just like the E-type, and the headlights are a departure from the simple elliptical lenses on current Jags.
The cabin is better packaged than previous Jaguar coupes, with improved headroom, multi-directional sports front seats, and individual bucket seats in the rear, while the interior is trimmed throughout in tan leather.
