The new Jaguar XF has been officially unveiled, in an event that saw British stunt man Jim Dowdall drive a new XF 240 metres across a wire suspended over Royal Dock in London’s Canary Wharf (video below).

Jaguar say the stunt was designed to highlight the new XF’s light weight, as a result of its extensive use of aluminium, with the company claiming the new car is 80kg lighter than its nearest competitor, and up to 190kg lighter than the outgoing model.

The car will make its public debut at the New York show on 1st April, but Jaguar is keen to make much of the new model’s efficiency, quoting economy figures of over 70mpg and CO2 emissions of just 104 g/km.

The new XF will be powered by a range of engines that starts with the company’s new Ingenium 2.0-litre four-cylinder units, offered in both 163PS/380Nm and 180PS/430Nm guises.  They’re available with either a six-speed manual or eight-speed automatic transmission.

A 3.0-litre twin-turbo diesel V6 will also be available, with an enticing 300PS and 700Nm of torque, as will a 3.0-litre V6 petrol unit with 380PS and 450Nm.

Jaguar’s new EPAS electric power steering system makes an appearance, together with specially-tuned passive dampers controlling the double wishbone and integral link suspension, with an Adaptive Dynamics system available as an option.

It works with Jaguar’s Configurable Dynamics to provide a range of settings not just for the dampers, but also steering, engine and transmission response.

All-Surface Progress Control helps in the search for traction at low speeds in low-grip environments, and is just one of many new technologies that are fitted to the new XF.

The cabin features a 10.2-inch colour touch-screen to provide infotainment and connectivity functions, complete with the company’s Dual View system that allows the front-seat passenger and driver to see different images on the same screen simultaneously.

Also new is a 12.3-inch colour display in the instrument pack, which the company describes as ‘fully reconfigurable’.

Full specifications will be confirmed at the car’s debut in April, but the company did say it would be the first Jaguar to offer full LED headlights.

The new Jaguar XF is expected to go on sale in the autumn.
