2010 Paris Motor Show: Jaguar C-X75 Concept

Article by Christian A., on September 29, 2010

In order to celebrate its 75th anniversary, Jaguar unveiled the C-X75 Concept, a new supercar with a remarkable design that will inspire future cars from the British manufacturer. Just like Audi used it on the e-Tron Concept, the new car uses four electric motors at each wheel. Each electric motor delivers 145kW (195bhp), which means that the car delivers a total output of 580kW (778bhp).

At the center of the car sit state-of-the-art, mid-mounted micro gas-turbines. These can generate 140kW (188bhp) to charge the batteries, or can be used in order to extend the range of the car to an impressive 900km (560 miles) – enough to drive from London to Berlin on a single tank.

The four electric motors deliver an impressive 1600Nm (1180lb ft) of torque. The car has a top speed of 330kph (205mph) and blistering acceleration, and a zero tailpipe emissions range of 110km (68 miles).

Inside, we find seats fixed to the bulkhead as in a single-seater racing car, as well as an impressive design. Dramatic theater lighting is activated as the driver approaches the car; phosphor blue electro-luminescent wire lights illuminate the perimeter of the cabin and the turbines. The car also features a new driver interface, which uses a high-resolution TFT screen.

Exterior Design

The new Jaguar C-X75 concept provides a glimpse of the carmaker's new design language while paying tribute to some of its most loved vehicles in the past. For instance, the new Jaguar C-X75 concept features natural flowing lines as well as simple yet elegant forms – characteristics of any Jaguar vehicle.

Moreover, a number of engineering and design elements of the new Jaguar C-X75 concept are inspired by past Jaguar cars like the 1950s C-Type and D-Type race cars and the 1966 XJ13 Le Mans prototype, which was described by Jaguar design director Callum as "the most beautiful Jaguar ever made."

Wrapped in Jetstream Silver finish, the Jaguar C-X75 concept makes use of active aerodynamics and an innovative propulsion system to pave way for a simple yet very stable fuselage section. Hinting at its high performance potential, the C-X75 concept was made to be shorter and lower than most supercars, featuring a simple central fuselage surrounded by wheel arches.

Since the new Jaguar C-X75 concept is not powered by a conventional piston engine, its engineers had more leeway in placing its mechanical components as well as coming up with the most elegant engineering package there is. Callum described the C-X75 as "everything a Jaguar should be" – having remarkable poise and grace as well as the excitement and potency of a true supercar.

He remarked that the C-X75 is as close to a pure art form as a concept car can get, adding that the vehicle is a worthy homage to 75 years of iconic Jaguar design. Inside, the C-X75 concept features fixed seats attached to the bulkhead just like in a single-seater racing car.

That’s why the steering wheel, main binnacle, controls and pedal box all adjust towards the driver. The body has channels that allow the air to pass through them to feed the turbines. On the other hand, the C-X75 is fitted with a new driver interface, using high-resolution TFT screens.

To help manage important and pertinent information is the Jaguar Co-Pilot display located in the vehicle's center console. The instrument binnacle serves as home for the main driver information screen, with twin cowls displaying the status and rpm of the two turbines.

Likewise, the cockpit of the C-X75 concept features designs from instrumentation in the new Jaguar XJ saloon and those from fighter aircraft, resulting to virtual 3D 'gimbals' around which the gauges wrap and rotate.

75 Years of Jaguar Design

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 C-X75 is finished in Jetstream Silver, its designers staying true to the long-held Jaguar design philosophy of natural, flowing lines and simple, elegant forms. Where inspiration from the past was found is in the innovative engineering and functional design elements of cars like the 1950s C-Type and D-Type racers and unique 1966 XJ13 Le Mans prototype -- a car described by Callum as "arguably the most beautiful Jaguar ever made."

Shorter and lower than the current crop of supercars, its exterior design is about pure performance with a simple central fuselage surrounded by prominent wheel arches. Thanks to the packaging efficiencies provided by the absence of a conventional piston engine, the car's designers had maximum freedom in placing the mechanical components and creating the most elegant engineering package available.

"The C-X75 is everything a Jaguar should be. It possesses remarkable poise and grace yet at the same time has the excitement and potency of a true supercar. You could argue this is as close to a pure art form as a concept car can get and we believe it is a worthy homage to 75 years of iconic Jaguar design."

Ian Callum, Design Director, Jaguar Cars

Propulsion system

The 205mph (330km/h) four-wheel drive supercar is capable of running in purely electric (zero tailpipe emissions) mode for 68 miles (109km) 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 560 miles (900km).

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 miniaturized 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 94 bhp (70kW) of power at a constant 80,000rpm.

Power and control

The energy created by the turbines and stored in the batteries is transmitted to the road using four independent electric motors. Using individual motors has benefits in terms of weight-saving and distribution, packaging and efficiency. Each motor weighs just 50kg but produces 195bhp (145kW) of power and an astonishing combined total torque output of 1,180lb ft (1,600Nm).

Because each wheel is driven by its own electric motor, the C-X75 is four-wheel drive -- with all the traction, grip and safety benefits that entails -- without the weight disadvantages of a purely mechanical set-up. Inherent in this drivetrain is the ability to independently vector torque to each wheel across the full speed range. This offers potential benefits in terms of stability and control, creating an infinitely and instantaneously adjustable traction and stability control system.

Driver-focused cabin

With the seats fixed, the steering wheel, controls, main binnacle and pedal box all adjust towards the driver. The seats are attached 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.

A new interface for the driver has also been created for the C-X75 using high-resolution TFT screens. Building on Jaguar's 10-year expertise in touchscreen technology, the Jaguar Co-Pilot display in the centre console supports the driver in extracting the full potential of the C-X75 by seamlessly managing information.

The main driver information screen is housed within the instrument binnacle. Needles float on the periphery of the twin cowls and sweep round the outer edge to display the status and rpm of the two turbines. The design team combined designs from instrumentation in the new XJ saloon with those from fighter aircraft to create virtual 3D 'gimbals' around which the gauges wrap and rotate to provide status updates.

75 years of innovation

"Performance through innovation has always been a Jaguar trademark. From the beginning, cars such as the C-Type and D-Type pioneered aluminum construction, aerodynamic design, racing monocoques and disc brakes. The C-X75 demonstrates that Jaguar is still leading the field automotive design and technology. And will always continue to build beautiful, fast cars."

Ralf Speth, Chief Executive Officer, Jaguar Land Rover

Advanced aluminum lightweight construction

Jaguar's expertise in the use of aluminum 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 realized 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 aluminum chassis clad in panels of the same material. Not only does this save weight, crucial in a car with an extreme performance envelope, but aluminum is one of the most easily recyclable metals available, boosting the C-X75's sustainability as well as its speed.

Active Aerodynamics

Aerodynamics have always played a large part in Jaguar design with the late designer Malcolm Sayer elevating it into an art form in cars such as the XJ13, the prototype from which the C-X75 draws inspiration.

Jaguar has increased the design's aerodynamic efficiency dramatically by opening the front grille and brake cooling vents only when necessary. At the rear corners of the car vertical control surfaces automatically engage at higher speeds to direct airflow aft of the rear wheels for increased stability and efficiency.

The carbon-fiber rear diffuser, a crucial element in guiding airflow under the car and creating downforce includes an active aerofoil, which is lowered automatically as speed increases. Vanes in the exhaust ports then alter the directional flow of the gases to further increase the effectiveness of the Venturi tunnel.
