True, there’s barely any more room in there than aboard the saloon – but its sides are so clean that you’ll convince yourself otherwise. And with the seatbacks folded impressively flat (another admirable internal target), the XF apparently boasts one of the longest loadspaces in its class.
As for what’s in the nose of the XF, you have the choice of five engines with most powered by a diesel unit, while the only petrol on offer is a 247bhp, 2.0-litre, four-cylinder affair.
Propping up the range is a 161bhp and 178bhp versions of Jaguar’s 2.0-litre Ingenium unit, with a twin-turbocharged version also available producing 238bhp. Topping the oilburner range is the silky, smooth twin-turbocharged 3.0-litre V6.
As for trims, there five to choose from at launch – Prestige, Portfolio, R-Sport, S and First Edition.
Entry-level models come with 17in alloy wheels, bi-xenon headlights, roof rails, rear self levelling air suspension and powered tailgate as standard on the outside. Inside there is a leather upholstery, heated front seats, carpet mats, rear parking sensors and Jaguar’s InControl infotainment system complete with an 8.0in touchscreen display, sat nav, DAB radio, USB and Bluetooth connectivity, and the ability to create a Wi-Fi hotspot.
Upgrade to Portfolio and the XF is adorned with 18in alloys, a Windsor leather upholstery, veneer dash trim, split rear seats, heated front windscreen, front parking sensors, a rear view camera, keyless entry and a 380W Meridian sound system.
The sportier looking R-Sport models get an aggressively styled bodykit, sports suspension, a dark headlining and gloss black exterior as standard. The range-topping S models get 19in alloys, a beefier body kit, aluminium interior trim and adaptive suspension.
Those looking for a little more exclusivity can opt for the tech-heavy First Edition model.
Getting acquainted to the XF Sportbrake
Inevitably, this all comes at a cost. To you, the buying public, it’ll be a premium of around £2500 over and above the equivalent saloon.
To the car itself, it’s weight. As well as requiring some more bodywork and the extra bracing that goes with it, Jaguar has fitted self-levelling air suspension to the Sportbrake’s shapely rear – meaning that, all told, your extra money pays for around 115kg of surplus bulk.
This slightly unwieldy fact does the latest 237bhp 2.0-litre diesel Ingenium unit no favours at all. Jaguar claims 6.4sec for the AWD version’s 0-60mph time; it feels at least a second slower than that in the real world and hasn’t shaken the slight sense of ponderousness identified during the Range Rover Velar’s road test either.
Combine the Sportbrake’s less-than-spirited overtaking performance with middling refinement under load and the niggle starts to swell ominously. Good job, then, that virtually everything else the car does works like a cold compress on the engine bay’s shortcomings.
The chassis’s benchmark was the saloon’s class-leading dynamic flair and, given the unsettling aspect of air springs and additional ballast, its mimicking of the XF’s trademark handling compromise is highly commendable. Measured against its passively sprung, rear-drive sibling, a modicum of direction-change athleticism has unarguably evaporated, but the wagon feels so assertively poised that it’s barely missed.
