Jaguar unveiled in 2010 the C-X75, a hybrid supercar offering impressive performance while returning fuel consumption ratings closer to those of a low-emissions city car.

Today, Jaguar released a behind-the-scenes film of the car’s development: C-X75 – A hybrid supercar prototype without equal.

The film features contributions from the car’s lead program engineers and reveals the challenges overcome in developing a vehicle with a 220mph top speed but that is also capable of producing less than 89g of CO2 per kilometer and can run with zero emissions for up to 60 kilometers (37.28 miles).

When Jaguar unveiled the C-X75 concept in 2010, the company said it was the beginning of a new chapter in innovation and technological advancement that would see the car evolve from a design study to a fully working prototype in just two years.

Since then, Jaguar said it has, with development partner Williams Advanced Engineering, created an all-wheel drive, plug-in parallel hybrid electric vehicle (PHEV) with the world’s highest specific power engine and Jaguar’s first carbon composite monocoque chassis.

Although the decision was taken in 2012 that as a result of the global economic climate the C-X75 would not enter full production, it was clear for the company that the hybrid supercar was a powerful showcase for Jaguar’s world-leading expertise in lightweight vehicle construction and the ideal test-bed for the company’s innovative research into high-performance, low-emission powertrains.

The C-X75 has a combined power output in excess of 850 horsepower, thanks to its state-of-the-art, Formula 1-inspired, 1.6-litre dual-boosted (turbocharged and supercharged) four-cylinder powerplant which generates 502 horsepower at 10,000 rpm.

Jaguar stated it is combined to the highest torque and power density electric motors in production, which generate a further 390 horsepower. The battery pack in the C-X75 is the highest continuously rated power PHEV pack in the world, capable of delivering more than 300 kilowatt over the full state of the charge window.

The C-X75 can sprint from 0-100mph in less than six seconds, thanks to its advanced 7-speed automated manual transmission that allows gearshifts in under 200 milliseconds. The very first C-X75 prototype exceeded 200 mph in testing with ease, and the car has a theoretical maximum velocity of 220 mph.

The car’s deployable aerofoil and underfloor aerodynamics create more than 200 kilograms of downforce at 200 mph, and active systems enhance its high-speed stability.
