The 2.0-litre diesel engines aren’t particularly efficient, producing more company car tax-swelling CO2 emissions than the best rivals. For example, even the lowest power 2.0 163 is more polluting than the 520d Touring, while the version that rivals the 520d on power - the XF 2.0d 180 - is even worse still. That said, if you have your heart set on an XF, we’d suggest the 2.0d 180 makes the most sense, because its added performance over the 163 is worth the extra company car tax.
The V6 diesel is also less efficient than six-cylinder diesel equivalents, such as the 530d Touring, but its emissions aren’t too far off the E400d Estate’s. Meanwhile, if you’re a private buyer and choose either of the 2.0-litre petrols, you’ll struggle to get more than 30mpg as an average.
In terms of equipment, entry-level Prestige comes with plenty of kit and makes the most sense. This includes dual-zone climate control, 17in alloy wheels, heated front seats, leather seats and a suede headlining, as well as the rear parking sensors, xenon headlights and infotainment features we’ve mentioned previously. Opt for R-Sport and, bar front parking sensors, you're getting mainly more aggressive styling, including black exterior trim detailing, bigger 18in alloy wheels (the 2.0d 163 retains 17in wheels) and a bespoke bodykit.
For that reason, have a look at the more luxurious Portfolio if you fancy a few more toys. It costs the same as the R-Sport but swaps the bodykit for more useful upgrades, such as keyless entry, higher-grade leather seat trim, a heated windscreen and power-folding door mirrors. Add in the 10-way electrically adjustable front seats, lumbar adjustment and the infotainment upgrades we’ve already covered, so it’s a decent proposition.
Range-topping S and special edition 300 Sport come only with the top-end engines, but aren’t really worth the price hike.
Every XF Sportbrake gets a host of safety equipment as standard, including automatic emergency braking, traffic sign recognition, lane departure warning system and six airbags. There’s also an optional Active Safety Pack, which adds useful additions including blind spot monitoring, lane keeping assistance, driver tiredness monitoring and a feature that warns you if you’re about to reverse into the path of oncoming traffic. The XF Sportbrake received a maximum five-star safety rating from Euro NCAP, scoring solidly in all four test categories.
An alarm and engine immobiliser are on hand to deter thieves. Indeed, security firm Thatcham Research has run its security test and awarded the XF full marks for its resistance to being driven away and four stars (out of five) for its ability to resist a break-in.
