Jaguar has unveiled the C-X75 concept, an extended range electric vehicle that uses twin gas micro-turbines from Bladon Jets to power two switched reluctance generators from SR Drives.Traction is provided by four 145 kW (195 bhp), 400 Nm (295 lb-ft) traction motors at each wheel for total drive power of 580 kW/780 bhp.
The plug-in, electric drive supercar has an all-electric range of 110 km (68 miles) plus a potential top speed of 330 km/h (205 mph), acceleration from 0-100 km/h (62 mph) in 3.4 seconds, and 80-145 km/h (50-90 mph) in 2.3 seconds. Active aerodynamics allow for a simple fuselage section that remains stable at very high speeds. The plug-in will produce 28 grams of CO2 per kilometre on the EU test cycle, according to Jaguar.
The mid-mounted 70 kW (94 bhp) micro gas-turbines can generate a combined 140 kW (188 bhp) to charge the batteries and extend the range of the car to 900 km (560 miles)—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, which Jaguar deems essential in a car that produces 1,600 N·m (1,180 lb-ft) of torque.
The driver and passenger are seated ahead of a sealed airbox that houses the micro gas-turbines. The seats are fixed to the bulkhead as in a single-seater racing car, and air to feed the turbines passes smoothly around them via channels in the structure of the body. With the seats anchored in place, the steering wheel, controls, main binnacle and pedal box all adjust towards the driver.
Jaguar is already aiming to reduce the drag coefficient of its future models in order to increase fuel efficiency. The C-X75 presented the additional challenge of managing the high volume of air required by the turbines. To achieve this active aerodynamics have been utilized for the first time on a Jaguar.
Advanced lightweight aluminium construction techniques provide weight-saving and economy benefits. Additionally, up to 50% of the metal content is recycled.
