Powered by a range of powerful, yet efficient, diesel engines in 2.2- and 3.0-litre capacities, the XF Sportbrake marks the debut of new derivatives based on the 2.2-litre diesel unit. The engine is now available in 163PS and 200PS outputs – the latter replacing the existing 190PS output engine. Both share highly competitive CO2 emissions starting from just 135g/km and economy of 55.4 mpg.

The Sportbrake will also be available equipped with a 3.0-litre turbocharged V6 engine in 240PS Diesel and 275PS Diesel S derivatives. Each emits 163g/km of CO2 and returns 46mpg on the combined cycle.

Despite its focus on versatility, in Diesel S form, the XF Sportbrake can accelerate to 60mph from rest in just 6.1-seconds. The 240PS variant can achieve the same feat in 6.7-seconds. 

The XF saloon also benefits from the new engine upgrades. Applied to the saloon, the new 2.2-litre Diesel engines share the same economy and CO2 figures as the Sportbrake. Deliveries of the saloon commence in September with prices starting at £29,940 on-the-road.

The XF saloon and Sportbrake will both adopt the eight-speed automatic gearbox and Stop/Start as standard across the engine range – improving emissions on the V6 Diesel engines by six per cent on the saloon.

For the first time, the XF range will also be available with the Meridian audio system – replacing the Bowers and Wilkins system and promising precise yet powerful sound quality via a sophisticated amplifier and high quality speaker units.   

Heading the XF range is the new XFR Speed Pack. Featuring a speed limiter raised to 174mph, the 510PS XFR Speed Pack car is equipped with revised engine and gearbox calibration to match the increased top speed. A new front aero splitter and a new rear wing distinguish the Speed Pack car.

Joining the range is a new 3.0-litre supercharged V6 petrol engine developing 340 PS. The engine, which is also set to appear in the new F-TYPE, replaces the naturally aspirated 5.0-litre V8 in the XF range. The 3.0-litre V6 S/C is capable of accelerating from 0-60mph in 5.7 seconds and on to a limited top speed of 155mph, returning fuel economy figures of 30mpg on the combined cycle and emitting 224g/km of CO2.
