The C-X75 concept is both a celebration of 75 years of iconic Jaguar design and a look into the future of automotive technology.
Designed as a range-extended electric two-seater supercar, it explores the outer limits of both performance and sustainability. With plug-in capability the car can achieve a zero tailpipe emissions range of 110km (68 miles) – three times round Paris’s Péripherique – when running under battery power alone, plus a potential top speed of 330km/h (205mph) and blistering acceleration.
The car demonstrates that it is possible to retain Jaguar’s core values of performance, design and luxury using technology that will make environmentally responsible performance and electric vehicles a practical proposition.
The C-X75’s 580kW propulsion system combines powerful 145kW (195bhp) electric motors at each wheel for outstanding performance. At the centre of the car sit state-of-the-art, mid-mounted micro gas-turbines. These can either generate 140kW (188bhp) to charge the batteries and extend the range of the car to a remarkable 900km (560 miles) – enough to drive from London to Berlin on a single tank – or when in Track mode provide supplementary power directly to the electric motors. The four electric motors provide torque-vectored, all-wheel drive traction and grip, essential in a car that produces 580kW (778bhp) and 1600Nm (1180lb ft) of torque.

Finished in Jetstream Silver, the C-X75’s beautiful proportions, sculpted lines and powerful stance have been created, in the words of Julian Thomson, to "pull at the same emotional heartstrings as classic Jaguars such as the D-Type and XJ13 racers.”
Using an underbody Venturi and directional exhaust gas control kept the car as sleek, compact and low as possible while still generating immense amounts of grip and downforce. Indeed, the movement of air itself was one of the principal drivers behind many of the design cues that were incorporated into the bodywork. Principal designer Matt Beaven reveals how the airflow into the turbines helped to shape the surfaces of the car itself: “We wanted to emphasise how the air makes its way not just over the car but is also channelled into the rear airbox. When operating at 80,000rpm, each gas-turbine requires 35,000 litres of air a minute which means we needed a series of carefully honed intakes.”
PERFORMANCE – 0-100km/h (62mph) in 3.4 seconds, a top speed of 330km/h (205mph) and 80-145km/h (50-90mph) in just 2.3 seconds

PROPULSION SYSTEM – 2 x 70kW (94bhp) micro gas-turbines and the plug-in Lithium-ion batteries provide power to four independent electric motors each rated at 145kW (195bhp) and 400Nm (295lb ft) of torque. These in turn provide drive to all four wheels

HUMAN MACHINE INTERFACE – Data from the car’s complex systems are shown on three information screens and can be transferred and filtered between displays as needed
British engineering firm Bladon Jets achieved a recent breakthrough in producing the multi-stage axial flow compressors – the technology used on all large gas turbines – on a miniaturised scale and to very high tolerances. This increased 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.
Electric motors also produce maximum torque from almost zero rpm, making the traditional power curve a thing of the past. In fact, such is the C-X75’s power that Jaguar’s engineers had to artificially limit the torque available from rest in order to improve the driveability of the car. The performance available in the mid-range is truly startling. The C-X75 will accelerate from 80-145km/h (50-90mph) in just 2.3 seconds. The quarter-mile sprint takes 10.3 seconds at a terminal velocity of 251km/h (156mph) and acceleration peaks at 0.88G.
Such astounding performance requires equally impressive braking. Jaguar already has a system proven to be up to the task. The C-X75 is fitted with the brakes used on the supercharged XFR which in 2009 became the fastest Jaguar ever, achieving 363km/h (226mph) at the Bonneville Salt Flats in Utah. In this application, regenerative braking technology on all four wheels helps recharge the batteries during driving. The 380mm internally ventilated front discs and 345mm rears are covered by polished alloy wheels of 21 and 22 inches wrapped in bespoke hand-cut Pirelli rubber measuring 265/30 ZR21 and 365/25 ZR22 front and rear respectively
