2017 Jaguar XF Sportbrake revealed as new BMW 5 Series Touring rival

Other markets will also offer Jaguar’s 375bhp turbocharged V6 petrol engine as a rangetopper, but this variant isn’t planned for launch in the UK. Nevertheless, deputy vehicle programme director Alan Hill told Autocar that "the engine could easily be added" to the line-up, should British demand be strong enough to justify it.

The XF Sportbrake weighs 1660kg in its lightest guise and is said to have a near 50/50 weight distribution.

The car is built on Jaguar’s lightweight aluminiumintensive architecture and has been given different chassis set-up from the saloon.

Despite the different settings, Hill said the model is retains the sporty setup of its sibling. Both cars feature a stiff double-wishbone front suspension that uses lightweight aluminium components. The XF Sportbrake has air springs at the rear in place of the saloon’s standard steel coils to enhance its load-lugging capability. The air springs have been designed to keep the body composed even when carrying loads and are claimed to be most effective when combined with optional adaptive dampers. The system is mounted to the same integral rear link set-up as the XF saloon.

The new estate comes with Jaguar’s Configurable Dynamics package as an option on automatic cars. This enables drivers to adjust the steering weight, throttle mapping and gearshift modes. Ride quality can also be altered on cars with adaptive damping.

Among the list of driver assist features is adaptive cruise control, blindspot monitoring and reverse traffic detection technology, as well as park assist. There’s also a driver monitoring system that can trigger alerts if the car wanders across lanes, or if the driver shows signs of fatigue.

 Jaguar's All Surface Progress Control system is included in all-wheel drive automatic cars and enables drivers to hand power over to the car in low grip scenarios, so it can juggle torque to each wheel automatically and therefore reduce the chances of the car getting stuck.

The new XF Sportbrake has 565 litres of boot space with the rear seats up and 1700 litres with them down. That beats the XF saloon by 25 litres and 815 litres respectively and is close to its key rival, the 5 Series Touring.

The XF Sportbrake’s rear seats come as standard with a 40/20/40 split and the rear audio speakers have been moved from the parcel shelf (where they’re located in the saloon) to the rooflining to further increase load space. The XF Sportbrake can also carry up to 100kg on its roof, thanks to a 320-litre luggage box that’s on the new car’s options list.

Jaguar claims the new XF Sportbrake can tow up to two tonnes, which is 400kg more than the XF saloon and F-Pace SUV can manage. Even the lowest-powered Sportbrake can pull 1900kg.

Jaguar’s new estate is 6mm shorter than the previous XF Sportbrake, but its wheelbase is 51mm longer, an alteration that is claimed to improve interior room and enhance the car’s ride. Jaguar says its new estate model has an identical drag coefficient to the saloon, at 0.29.

The XF Sportbrake has an estate shape that, unlike the first-generation Sportbrake, was part of the design plan from the new XF’s very beginning. Jaguar design director Ian Callum said this early integration into the XF model plan enabled the team to create an exterior design that’s actually sportier than the saloon’s.

“When we did the first [Mk1] Sportbrake, it wasn’t planned from the start,” said Callum. “But this time, the Sportbrake has been designed in before, so we could change [the design] from the B-pillars [backwards] straight away.”

The car’s rear does away with the curvaceous design of its predecessor for a more aggressive look. It features Jaguar’s most recent style of slim tail-lights, ensuring the XF Sportbrake is in line with the F-Type sports car and the F-Pace SUV. Above the rear lights, the rear window line is heavily raked like the firstgeneration Sportbrake’s, but it finishes more abruptly at a continuous line that runs around from the side of the car and extends all the way to the front wheel arches.

“It’s better-looking than the saloon, I think,” said Callum. “It gives us the chance for a lovely sweeping roofline and a sense of movement. It’s a very elegant car. The window graphic has a very elegant shape.”

The front of the car is familiar from the XF saloon, as is the cabin, but the Sportbrake introduces a panoramic roof to the XF range. It also has a gesture control feature for the tailgate, which can be opened when a foot is waved under the rear of the car and the car’s key is within close range.
