Jaguar wow press and public with a daring hybrid supercar concept built to celebrate their 75th year

Running gas turbines in road cars is not a new idea. Think back to the 50′s-60′s when Chrysler ran a fleet of turbine cars, and BRM fielded a Le Mans racer. These were short lived experimental projects that followed the motor show dream concepts of the time. Interesting ideas but flawed in many ways and connected mechanically to the drivetrain. Using gas turbines to generate electricity for electric drive motors solves the immediate problem of reducing the phenomenal RPM and throttling of a turbine down to the low rotation needed for your wheels and tyres. It also allows the turbine to run at optimum speed for the efficiency that eluded earlier iterations. If Jaguar have solved the remaining problems of heat and emissions, then we have the recipe for an interesting vehicle. 4 wheel drive, infinitely controllable for traction and yaw, electric drive supplemented by turbine generators, bring it on Jaguar. Lets hope this is not just pie in the sky and points the way to a new and exciting future for supercars.

Propulsion system

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.
