The cars with the biggest boots
Forget the official figures. What Car?'s unique way of measuring boot space reveals the cars that really have the biggest luggage capacities...
Boot space is a priority for many car buyers. And if a particular model simply doesn’t have enough room to handle all your kit, then it has to be struck from the shortlist.
That’s why we’ve compiled a list of the cars with the biggest boots on sale today, using our own unique method of measuring the available space.
All manufacturers list boot sizes by litres, but that includes the nooks and crannies of a boot that are – in reality – very hard to make use of.
Instead, our independent test team uses carry-on suitcases to realistically assess each car’s cargo capacity. The more suitcases we can fit in the boot, the better the car for buyers who need to transport big loads.
Every car on our list can carry between nine and 12 suitcases, making them the most spacious models we've tested.
Cars that can carry 9 suitcases
Even in saloon form, the Audi A6 has a large enough boot to earn a place on this list. The luxury car can swallow nine suitcases, which is enough to outdo all of its direct competitors except the Mercedes E-Class, which it matches. Build quality is superb and the interior very attractive.
It's not quite as accommodating as the seven-seat Q7, but the Q5 still offers a massive amount of boot space given its relatively compact size. A top-notch interior and lower running costs than the Q7 also work in its favour.
BMW 6 Series Gran Turismo
The BMW 6 Series Gran Turismo sits between the 5 Series and 7 Series luxury saloons, but its sleek, hatchback-style tailgate makes it more practical, and it’s possible to fit nine suitcases in the boot. It’s only just shorter than the 7 Series, but based on the 5, which is a sensational all-rounder.
Citroën C5 Aircross
It's very easy to get bulky items into the boot of the C5 Aircross, thanks to a large aperture, while the load space itself is tall and square. Mazda's otherwise brilliant CX-5 is just one of the rivals it betters in this area, while the C5 also offers a super-smooth ride.
The CR-V is another large SUV that can swallow nice carry-on suitcases. Just bear in mind that this is only the case if you go for the five-seat version; Honda has essentially bolted the additional seats of the seven-seater to the boot floor rather than integrating them properly like most rivals do, so the boot size is reduced considerably. Unlike the C5 Aircross, the CR-V is available with hybrid power.
Not so long ago, the Lexus RX was the only hybrid luxury SUV around (there are plenty more these days), but it was hampered by its lack of a seven-seat option. The RX L rectified that by adding a longer rear overhang to make room for a third row. And when this is folded away you can just about squeeze nine suitcases into the boot.
Mercedes E-Class/E-Class Estate
As long as you avoid the E300de hybrid, the E-Class has a bigger boot than any of its luxury saloon or estate rivals. Add in an extremely classy interior and superb refinement, and it's a compelling package, even if the BMW 5 Series is more enjoyable to drive.
The Karoq is the smallest SUV on our list, making its presence even more impressive. The boot is very well laid out and includes a smaller storage area below the main luggage section for storing delicate items. Even without using that, though, it’s possible to fit nine suitcases inside.
If the Karoq isn’t quite big enough, the Kodiaq is the logical next choice. It’s Skoda's largest SUV, with seven seats for maximum practicality. And while it couldn't swallow any more cases than the Karoq, there was more room to spare for smaller items.
