Jaguar C-X75 concept
When we first set eyes on Jaguar's stunning C-X75 concept at this year's Paris Motor Show it was clear that the company had been busy in the design studio. Although big, broad and essentially rather improbable in current form, the C-X75 is remarkably beautiful - a voluptuous supercar concept that simply doesn't slot anywhere in Jaguar's current and future product road map. So why create it? Concept cars aren't cheap, and their design, construction and short but glorious globe-trotting lifespan needs to tick a lot of boxes to justify the investment.

Ian Callum, Jaguar's long-standing and highly engaging director of design, remarks wryly that the C-X75 exists as a bit of a provocation. 'It's a disruption, really, that's part of my job.' Ostensibly created to celebrate the marque's 75th anniversary, it's also an undisguised attempt to splice a rich mix of low emission technology and sporting excellence into Jaguar's DNA. This particular territory - the realm of the hyper-efficient supercar - is currently very much up for grabs, with the forthcoming Porsche 918 Hybrid, Mercedes' all-electric SLS roadster and Audi's e-tron all in the running but each still several years from production.
The C-X75 could never be built as it stands, for the technology it contains is largely speculative. The show car is electrically powered, with a motor at each wheel, but the cleverest conceit it contains is still theoretical. This is the inclusion of two tiny gas turbine engines, each designed to spin at speeds of 80,000 rpm and dedicated to rapid re-charging of the car's batteries.
On electric power alone, the C-X75 should be good for 80 miles or so. Top up the turbine tank with kerosene, diesel or some other highly concentrated fossil fuel, and you have a high-tech range extender system, one with an evocative whine that evokes the right combination of retro-futurism and genuine future shock.
That's the theory. In practice, the turbines have never been spooled up. Instead, they sit beneath a glass engine canopy like a couple of fancy thermos flasks. Jaguar's parent company, Indian industrial giants Tata, has taken a stake in the turbine makers, Bladon Jets, a small Midlands-based business, with a long-term view to micro-power generation in parts of the world with minimal infrastructure. Supercars are simply a sideline.
In recent years, the auto industry has rather fallen out of love with the show car as an unattainable dream. Back in the 1950s and 60s, the Americans and Italians attempted to outdo each other with the most voluptuous and improbable pieces of automotive sculpture, nakedly futuristic concepts that were squarely aimed at psyching up the consumer for a distant 'world of tomorrow' - an airbrushed, proto-Pop, hyper-chromed push button place of perpetual freedom.
The majority of today's concepts are rather more prosaic, being much more closely related to imminent production models. The gestation of a new car is so prolonged and complex that the conceptual designs that appear to 'precede' them are inevitably designed after the standard car has been signed off and is waiting quietly in the wings. The C-X75 is different - one of a group of ultra-efficient supercars revealed in recent years. Although its very radical nature means that it's unlikely to hit the road in its current form, the prototype conforms to most current legislation, the rigid set of rules through which all car designers must squeeze their brand identities. Look out for it on the virtual realm of Gran Turismo rather than a real road.
For Callum, the chief lessons to learn from this concept are that electric propulsion is a blank slate for designers. 'We can make an electric car almost any shape we like,' he explains, 'there's nothing mechanical, no great big lump of gearbox or V8.' Rumour suggests a new smaller, sporting Jaguar is in the offing, and perhaps elements of this machine will surface in that - a curve here, a crease there. Most importantly of all, this concept exists to help spark up a relationship between electric powertrains and emotion, the irrational wildcard that cements our attachment to a particular brand.
Rather perversely, given the lack of limitations, the C-X75 shares its proportions with Jaguar's own XJ13, a one-off mid-engined special from 1966, and as classic a piece of old-school, fossil-fuelled race car engineering as one could possibly find. Yet if this current concept achieves the same legendary status as its 60s forerunner, regardless of the improbability of production, Callum and his team will have done their job.
