The new 1.6-litre engine used to power Jaguar’s cutting-edge new Jaguar C-X75 hypercar will rev to 10,000rpm and use both a turbocharger and a supercharger to generate around 500bhp, the manufacturer confirmed today.
It will supplement two electric motors positioned on the front and rear axle that Jaguar is confident will outperform any of its forthcoming rivals in the fast-growing electric supercar niche. The team behind the C-X75 project reiterated that, as they move into the working prototype stage, they are confident of a 200mph top speed and sub 3.0sec 0-60mph time.
Despite the presence of the extraordinary four-cylinder petrol unit (which, for now, replaces the dual jet turbines that featured on the 2010 concept) and its implied performance, Jaguar has gone to great lengths to make its plug-in, range-extended, six-figure machine a viable hybrid. Thanks to a liquid-cooled, 200kg battery pack, which is the heaviest component in the car, the C-X75 is projected to deliver an all-electric range of 60km, and will still manage 0-60mph in 6.0sec without resorting to internal combustion.
The 600v battery is situated as close to the centre of the car as possible, just 85mm from the engine, which in turn is mid-mounted. Jaguar says it has worked hard to package all the heaviest components within the wheelbase, with even the rear-mounted seven-speed automated manual gearbox within the wheel shadow. The transmission is a legacy of the measures taken to save weight. The manufacturer believes it has saved around 100kg by not choosing a dual-clutch unit.
As previously revealed, the C-X75 will use Jaguar’s first carbonfibre-intensive structure. The bonded monocoque, formed from a carbonfibre tub and connected rear frame, has been created in conjunction with the Williams Formula 1 team and has enjoyed direct technical transfer from the F1 track.
It was originally believed that the engine may have benefitted from the same lineage as Formula 1 will soon adopt the same 1600cc capacity, but the team revealed that the powerplant is an all-new design which has been conceived and constructed in-house at Gaydon.
As it uses a supercharger and a turbocharger to deliver power at a different ranges, it employs both direct and port-fed fuel injection to maximize either efficiency or power depending on driver requirements.
That power is sent to the rear wheels or used to charge the battery, where it supplements the energy delivered via a wet clutch by the electric motor on the back axle. This is transmitted through the gearbox, but the electric motor up front is on a single transmission capable of working through the full spectrum of the C-X75’s performance.
As it never decouples, this means the car works with permanent four-wheel drive, a function Jaguar says will be vital to the handling characteristics of the final model.
Though as yet unseen, or indeed ultimately confirmed for production, it has already been suggested that the design flair exhibited on the stand at the Paris motor show two years ago has been carried across to the C-X75's road-going production successor, and that it will benefit from active aerodynamics. In particular, this will benefit the car's cooling; it currently sports 11 radiators to cope with the huge heat generated.
Assuming it sees its way successfully through the remaining development stage, Jaguar has reconfirmed its intention to build around 200 examples of the C-X75, and indicated that they will cost in the region of £700,000-£900,000.
