The Numbers Don't Tell the Whole Story
Volvo XC40 boot capacity is listed at 460 litres with seats up, dropping to around 1,371 litres with them folded. Volkswagen's Tiguan comes in at 615 litres in the same configuration, expanding to roughly 1,700 litres when you squash the rear row flat. On paper, that's a clear gap. But if you've actually tried to load both cars with real-world stuff—prams, suitcases, a bike frame you're half-heartedly trying to fit—you'll find the numbers lie to you a bit. What matters more than the sticker number is the shape of the load bay. The XC40 has a tall, relatively boxy cargo area with a high load lip. You can stack things vertically without worry, which is great for tall items like a vacuum cleaner or a bag of potting soil. The Tiguan, by contrast, has a wider but lower boot with a slightly sloping rear profile when the seats fold. It swallows wide loads better but you lose stack height. I learned this the hard way last year when I tried to fit a boxed office chair into my XC40 to move it to a friend's flat. The chair was 95 centimetres tall. The specs said the boot would take it folded. It didn't work. The load lip was too high and the opening angle of the rear hatch, while generous, just wouldn't let me slide it in at the right angle. I ended up throwing the chair over the back seat from inside the car, which nearly snapped the seat hinges. The workaround was taking the seat backs off entirely—they unbolt with a 10mm socket in about three minutes each—and now the chair slides right through.
The Tiguan wouldn't have had that problem at all. The load floor is lower, the opening is wider, and the chair would have slid in without the seat coming out. That's the real trade-off here, and it's something the marketing sheets don't emphasize. Here's what people get wrong about these two comparisons: The Tiguan's 615-litre figure is measured using the VDA method, which fills the space with uniform 120x80x60mm blocks until they can't go any further. The XC40 uses the SAE J2449 standard, which measures differently—partially based on the usable horizontal plane rather than pure volume. When you convert both to the same measurement methodology, the gap shrinks to roughly 40-50 litres instead of the 155 litres the spec sheet suggests. You're not losing a whole golf bag of space in practice. But you are losing ground clearance under the load lip and overall width usability.
Another counter-intuitive point: the XC40's underfloor storage compartment is genuinely useful in a way most people overlook. There's a dual-level false floor that creates a deep well beneath the main boot surface. I keep my emergency kit, first aid box, and charging cables down there, which means the main load area stays completely clear. The Tiguan has a similar setup but it's shallower and narrower—more of an afterthought than a proper feature. If you're loading frequently large, irregular items like furniture or bulky sports gear, the Tiguan's lower load height and wider aperture make it the more forgiving choice. If you're mostly transporting groceries, luggage, and tall narrow items, the XC40's vertical efficiency and deeper hidden storage might actually serve you better day-to-day. The real bottleneck with the XC40 isn't the boot size—it's the wheel arch intrusion. The rear wheel housings poke significantly into the load bay on both sides, which means wide items like a sheet of plywood or a long skateboard won't lie flat across the full width. You end up stacking things at an angle or losing usable width. The Tiguan has the same issue but it's less pronounced because the floor is wider overall and the arches are further apart relative to the total space.

I'd recommend measuring your actual regular loads before making a decision. Grab a tape measure and put it in the boot of each car. See what fits. The 50-litre difference in converted figures won't matter much, but the shape, the load lip height, and the wheel arch intrusion will make all the difference when you're actually standing in your driveway at 7am trying to cram everything into the car for a weekend trip.
