Jaguar says this is the lowest CO2 figure in the class for any non-hybrid vehicle. It’s well down on today’s BMW 518d, which has an official rating of 114g/km, as well as a lower-powered, 141bhp engine.
The company says there will also be a 178bhp, 317lb ft, 2.0-litre Ingenium diesel XF. Both of these engines can be combined with an eight-speed automatic gearbox.
Jaguar says that the eight-speed auto ‘box was chosen over a nine-speed as it offers the best calibration. A nine-speed would have efficiency benefits, but the eight-speed offers a better torque spread.
At the top of the diesel range is a tweaked version of the familiar twin-turbo 3.0-litre V6, which offers 296bhp and 516lb ft of torque.
The only petrol-engined version that Jaguar has so far released details about is the supercharged petrol V6, which develops 375bhp and 332lb ft of torque.
Inside, the XF has a completely different design language from Jaguar’s XJ flagship. Rather than the XJ’s flamboyant circular vents and much more extravagant detailing, the new XF has a rather more contemporary and sparse appearance inside.
The centre console is notably wide, with plenty of storage space, and the interior detailing - both the brightwork and wood trim — is given a very lean and taut treatment. The XF gets the familiar pop-up rotary controller for the automatic gearbox selector and the outer air vents roll open when the car is started.
The new XF comes with a big, 10.2in ‘dual-view’ smartphone-like touchscreen and JLR’s latest multimedia system, known as InControl Touch Pro. The main instruments are displayed on a 12.3in TFT panel, which can be reconfigured.
Jaguar will offer the new XF in Prestige, R-Sport, Portfolio and S specifications. Top-end S models get Jaguar’s Configurable Dynamics system, which allows drivers to adjust the dampers, steering, engine and transmission settings to suit their driving style.
Other options include Jaguar’s All Surface Progress control system, as well as a laser head-up display, adaptive cruise control and LED headlights. All-wheel drive will not be offered in the UK, but it is all new and 18% lighter and 10% more efficient, and has a rear-drive bias.
The car’s safety suite consists of autonomous emergency braking, lane departure warning, lane-keep assistance and traffic sign recognition systems.
The XF actually had its best year on sale in 2014 - 48,000 were sold. In total, 250,000 were sold since 2007.
Q&A with Ian Callum, Jaguar design director
What was your aim in designing the new XF?
"We created the first XF and defined its character, so it was a challenge to replace something we understood already. We've made it more pragmatic; more space is a good thing.
“I wanted to protect Jaguar’s visual DNA and I wanted to make sure that we created a genuine sports saloon. However, I also wanted the new XF to be more mature and sophisticated than the previous car. It may be slightly shorter and lower than the old XF, but I wanted the car to have more presence, which I think we’ve achieved.
"It's a simple, intelligent design. It has to work for seven years and I believe this will.
