It's called the "2020 Jaguar XJR-19 LMP1 Concept Race Car" and is !!!error: Indecipherable SUB-paragraph formatting!!! 's vision of what an LMP1 entry from Jaguar would look like. Personally, I find this concept to be much more appealing than the current LMP1 offerings from Porsche, Toyota, Audi, and Nissan but would interested to hear your opinions.

In 1988 and 1990, the Silk Cut Jaguar factory team ended 8 years of Porsche dominance at Le Mans with the iconic XJR-9 and XJR-12 group C racers. The XJR-19 is a prototype race car concept for the year 2020, to celebrate 30 years since Jaguar's last win at the legendary 24hr Le Mans race.

The design process of the XJR-19 was heavily influenced by the XJR-9 and XJR-12, focusing on cutting a smooth, fluid shape into a primarily rectangular form. This created a central pod consisting of the passenger cell and drivetrain, suspended between a skeleton of sharp, flat surfaces that echo the slab sided group C racers of the 1980s and 90s.

The upper surfaces were penned to create a smooth, unbroken graphic front to back. The large overhanging nose and wings on each side contrast strongly with the technical, recessed surfaces underneath. This helps illustrate the controlled airflow around the aerodynamic elements of the bodywork and the cooling intakes for the engine, brakes and suspension components.

The structural design of the XJR-19 emphasizes lightness. As well as removing all extraneous bodywork, all 4 wheels are independently housed away from the central structure, facilitating much quicker repair and refit of body panels in the event of a crash. The front suspension also replaces the entire lower wishbone with large, adaptive aerodynamic surfaces that act as the front spoiler.

The XJR-19 takes advantage of unique and futuristic material technologies, including structural batteries for large areas of the chassis and aerodynamic components. By creating a material that will hold a charge between two conductive carbon layers and curing it like a traditional composite, the need for heavy on-board lithium battery packs is eliminated. The remainder of the bodywork is composed of carbon nanotube reinforced polymer (CNRP). A material which impregnates carbon nanofillaments into epoxy along with carbon matting for added rigidityand toughness, making it stronger and lighter than traditional carbon fibre or kevlar.

The powertrain is a hybrid system of a turbo and supercharged 2.7 litre diesel V8, combined with a gearbox-mounted electric motor. The system employs a kinetic energy recovery system (KERS) in the form of regenerative braking systems, and magnetic shock absorbers which convert suspension movement and vibration into electrical energy.

( !!!error: Indecipherable SUB-paragraph formatting!!! )

However, I found this exert from Goodwood's website quite fascinating (emphasis mine):

Similarly, being a long-distance racer for the near future it's intended to run a 2.7-litre diesel V8 using both an exhaust-driven turbo and an engine-driven supercharger as well as 'structural batteries' which consist of a material which will hold a charge between two conductive carbon layers – therefore doing-away with the need for heavy on-board batteries.

Can anyone explain what they could be referring to in the bolded section?

Structural batteries are self explanatory. The body or frame IS the battery, rather than carrying them as a separate energy cell.

Oh interesting.
