FOUR-WHEEL DRIVE ELECTRIC SUPERCAR UNVEILED AT PARIS
Jaguar has revealed a stunning range-extended electric supercar concept car. The C-X75 has been designed to celebrate 75 years of the marque and provide a glimpse into the future of Jaguar and its commitment to producing beautiful, fast cars powered by sustainable means.
The C-X75 hints at an exciting evolution of Jaguar’s design language while paying homage to some of its most admired cars of years gone by. Advanced design features such as a ground-breaking propulsion system and active aerodynamics allow for an elegantly simple fuselage section that remains stable at very high speeds.
The 330km/h (205mph) four-wheel drive supercar is capable of running in purely electric (zero tailpipe emissions) mode for 110km (68 miles) on a six-hour domestic plug-in charge. The innovative, lightweight micro gas-turbines are also capable of very quickly and efficiently recharging the Lithium-ion batteries, giving the car a theoretical range of 900km (560 miles).
This remarkable range-extension system is a result of Jaguar’s research engineers adopting a clean-sheet approach to the question of powering the supercars of the future. The C-X75 turns to the very latest evolution of a pioneering British technology: the gas turbine.
Developed in partnership with Bladon Jets, the miniaturised turbine blade – the first viable axial-flow micro-turbine – increases the compression and efficiency of micro gas-turbines to the point at which they can be viewed as a realistic power source. Each of the micro gas-turbines weighs just 35kg and produces 70kW of power at a constant 80,000rpm.
Advanced aluminium lightweight construction
Jaguar’s expertise in the use of aluminium stretches back more than 50 years to the first XK120s, through the lightweight E-Types, the XK and all-new 2010 XJ. It was with this latter creation that Jaguar fully realised the lightweight metal’s benefits to performance, agility, economy and sustainability in a luxury car.
The C-X75 naturally follows the same construction techniques with an extruded and bonded aerospace-inspired aluminium chassis clad in panels of the same material. Not only does this save weight, crucial in a car with an extreme performance envelope, but aluminium is one of the most easily recyclable metals available, boosting the C-X75’s sustainability as well as its speed.
