Following the introduction of the C-X75 hybrid supercar prototype to the media for test evaluation earlier this month, Jaguar has today released photos as well as a behind-the-scenes film of the car’s development.
The film features contributions from the car’s lead programme 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 kilometre and can even run with zero emissions for up to 60km.
When Jaguar unveiled the C-X75 concept in 2010, it marked the beginning of a new chapter that would see the car evolve from a design study to a fully working prototype in a period of two years.
In that short timespan, Jaguar and development partner Williams Advanced Engineering have 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.
“The C-X75 programme represents the pinnacle of Jaguar’s engineering and design expertise. It is arguably the world’s fastest test-bed for the world’s most advanced technologies, combining as it does a remarkable hybrid powertrain with awe-inspiring performance. Jaguar is always looking to shape the cars of tomorrow and with projects like C-X75 we are laying the foundations for the next generation of Jaguar innovations,” says Adrian Hallmark, Jaguar’s Global Brand Director.
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 that it was a good showcase for Jaguar’s developing expertise in lightweight vehicle construction and the ideal test-bed for the company’s research into high-performance, low-emission powertrains.
The achievements in the development of C-X75 prototypes will be utilised in other areas of research and development, including future products and next-generation engineering for the Jaguar and Land Rover brands.
The C-X75 has a combined power output in excess of 850bhp and 1000Nm of torque, as a result of its Formula 1-inspired, 1.6-litre dual-boosted (turbocharged and supercharged) four-cylinder powerplant which generates 502bhp at 10,000 rpm.
It is allied 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 300kW over the full state of the charge window.
The C-X75 can sprint from 0-100mph in under six seconds owing to its 7-speed automated manual transmission that allows gearshifts in under 200 milliseconds. The very first C-X75 prototype exceeded 200mph in testing with ease, and the car has a theoretical maximum velocity of 220mph.
The car’s deployable aerofoil and underfloor aerodynamics create more than 200kg of downforce at 200mph, and active systems enhance its high-speed stability.
Thanks to the most extreme PHEV specification of any mobile battery in development, the C-X75 will also run for 60km in pure electric vehicle mode and its CO2 emissions fall below 89g/km.
