A four-door Jaguar F-Type could be somewhere in the line's future, if Jaguar's head of design gets his way.

Speaking to Australian media at the Geneva motor show this week, Jaguar design director Ian Callum confessed he is fascinated by the idea of a Jaguar F-Type 'four-door coupe'.

Callum also revealed that earlier engineering limitations that had precluded such an idea - similar to the above independent, speculative design by Design Q in the UK - are now gone.

As for confirming any plans, however, Callum quipped: "I couldn't possibly comment... Could you imagine that?"

"The notion of four doors is interesting because the idea of a four-door coupe came out originally with Jaguars, and then Mercedes-Benz latched on to the CLS and created this genre of car, which really rightfully was Jaguar's...so that's our rightful place in some ways — the four-door sports cars," Callum said.

Mercedes-Benz has found great success in the CLS, with the model spawning a number of high-performance variants and even a shooting-brake wagon.

Callum says that Jaguar, now celebrating 10 years of partnership with Tata and being given free rein on design, could now make this kind of design work in production.

"The four-door aspect of a sports car makes a lot of sense. Not for every sports car, don't get me wrong, but the reason for two doors is for more structure out of the car," he said.

"Therefore, four doors... and now, with modern technology, that sort of stuff doesn't really matter any more. We can engineer a car to have structure with four doors, or even pillarless doors these days."

"So the notion of what probably originated as a two-door car isn't relevant any more, if you can put four seats in it. There's definitely a trend towards 'four-seater being four doors'," said Callum.

Could this be the first signs of a bigger version of the F-Type? Could be. No doubt with Callum's team penning the design, it's a car that would certainly look the part.
