The Jaguar C-XF | Part Six

Jaguar C-XF

Powertrain (Componentry)

Beneath the C-XF's bonnet, further technical excellence is immediately apparent. The car is powered by an enhanced version of Jaguar's renowned 4.2-litre supercharged V8 engine. Tuned to produce in excess of 420bhp and 500Nm of torque - the latter produced from very low revs - this proven powerplant and its six-speed automatic transmission with Jaguar Sequential Shift manual gearchange capability, deliver superb sporting performance. If C-XF were a production car, it would reach an electronically limited top speed of 155mph, with the possibility of an unrestricted speed in excess of 180mph.

And the technology advances continue here, too, with the electrical architecture for the 4.2-litre engine encased in a unique carbon-fibre wiring 'loom'. Designed and constructed by Beru F1 Systems, the electrical 'spider' harness is not only beautiful but also extremely functional.

"The new wiring loom is a designer's dream," says Julian Thomson. "We thought we would always have to live with the plethora of wires that runs around an engine bay. Now every wire is housed within a visually stunning harness that looks as if it is literally strapping the engine down, holding all that power in place."

The C-XF is the first car ever to use Beru F1 System's unique Wire in Composite (WIC) technology . WIC completely encloses all wiring in a bespoke carbon-fibre sleeve, protecting it from damage and also improving durability, packaging, weight and aesthetics. As the first vehicle to use the technology, the C-XF leaps ahead of upcoming debuts in both Formula 1 motor racing and the aerospace industry - and allows Jaguar to further investigate production car potential for the system.

Jaguar C-XF Summary

The C-XF is not just another concept car - it is much more than that.

The exterior design is pure, athletic and, of course, beautiful.

The striking interior design uses traditional materials, but fashioned in new and contemporary ways.

The four-seat cabin - sufficiently spacious but not a bland, featureless expanse - is a welcoming, rewarding place to be.

The technologies and innovations are typical of the features on a Jaguar - and preview others that are still under development.

The powertrain - a supercharged V8 of proven excellence and a sophisticated six-speed automatic that delivers lightning-quick manual gearchanges thanks to the Jaguar Sequential Shift System - is perfectly suited to a true sports saloon.

The sum of the C-XF parts is impressive enough, but the whole - an exciting, modern, dynamic sports saloon that evokes absolute desire - is an extraordinary preview of the Jaguars of tomorrow.

"The Jaguar C-XF concept is the most dynamic and modern four-door car that Jaguar has ever created, a design showcase heralding the next generations of our sports saloon models. It signals a future for Jaguar that is as exciting as the C-XF itself."
