Both engine variants offer identical fuel consumption and CO2 emissions at a claimed 57.6mpg (combined) and 129g/km. The four-wheel-drive system and beefed-up bodywork adds more than 120kg to the kerb weight.
For all that, emissions and economy are still very good, with both this manual-only, 148bhp version of the 2.0-litre diesel, and the auto-only, 181bhp range-topper achieving just 129g/km and 57.6mpg.
It doesn't feel much different to a standard Seat Leon ST to drive, and that's no bad thing. Sure, there's more body roll, but unless you're planning on doing competition slaloms in your family wagon, it's progressive enough not to be a problem.
Perhaps more noticeable are the pitch and dive along with a touch of body float over undulations, but even that's easily ignored.
The steering is perhaps lighter than some would want and never feels very communicative, but it weights up progressively and gives enough feedback to give you confidence in faster stuff while still making easy work of car park shenanigans.
Despite that softer suspension, the X-Perience's ride is actually a bit more unsettled than that of the standard car's. It's nothing you'd call uncomfortable, but it can be pretty jarring over heavy mid-corner ruts and it feels busy over high-frequency bumps and ripples.
Still, it settles enough to make this a relaxed motorway cruiser, and the engine helps give it good motorway legs. This familiar motor actually gets a touch more torque in this model over the 148bhp 2.0 TDI in the standard Leon, and it serves up a hefty mid-range punch that makes fast, smooth driving really easy.
Given that this is a car that's undeniably non-sporting in its intentions, the 181bhp model is probably only worth the extra cash if you really want the automatic transmission.
Refinement has definitely suffered a little in the name of added ruggedness, both in terms of a bit more suspension noise and much more noticeable tyre roar on the motorway, the latter being the more bothersome at higher speeds. Engine and wind noise, meanwhile, are generally easily ignored.
The interior remains unchanged, so it is as practical as that of any Leon ST. It's unsurprisingly short of the outright roominess of a Skoda Octavia Estate, but will still cope with four people and lots of luggage with ease.
It also gets loads of equipment even in SE, with rear parking sensors, dual-zone climate control, leather-trimmed sports seats and interior LED lighting the chief additions over the standard ST's SE trim. Upgrade to SE Tech and your X-Perience will include 18in alloy wheels, adaptive LED headlights, front parking sensors, auto wipers and lights, an Alcantara upholstery and Seat's 6.5in touchscreen infotainment system complete with DAB radio and sat nav.
If you're after a spacious family estate that'll do dirt tracks, muddy yards and the odd damp grass slope with more aplomb than your average front-wheel drive wagon, this is well worth a look. Mind you, be sure that the standard front-wheel drive Seat Leon won't do the job, since it's more refined and quite a bit cheaper.
If you must have four-wheel drive, the Skoda Octavia Scout is usefully bigger and a bit cheaper kit-for-kit, making it the more common-sense choice if the Leon's sharp looks don't swing it for you. While the Volkwagen Golf Alltrack is the slightly more premium option for those keen on an off-road able estate.
