Citroën C5 Aircross Boot Size: 580 Litres — The Modular SUV With Three Sliding Rear Seats
The Citroën C5 Aircross (2018–present) has 580 litres of boot space with a modular rear bench — each seat slides and reclines independently. A 79 cm aperture height loads large bags upright. Complete guide.
The Citroën C5 Aircross (2018–present) stands out in the compact SUV segment for its modular rear seat system — three individual seats that each slide forward and recline independently. This lets you trade rear passenger legroom for boot depth on a seat-by-seat basis. Default boot volume is 580L with the bench in the mid position. The 79 cm aperture height is one of the most generous in the class, beating the Nissan Qashqai (78 cm), Kia Sportage (79 cm), and Ford Kuga (73 cm).
Citroën C5 Aircross Boot Dimensions (2018–present)
| Measurement | Rear seats mid | Rear seats forward |
|---|---|---|
| Boot volume | 580 litres | ~720 litres |
| Floor width | 110 cm | 110 cm |
| Load depth | 93 cm | ~120 cm |
| Internal height | 78 cm | 78 cm |
| Aperture width | 108 cm | 108 cm |
| Aperture height | 79 cm | 79 cm |
The 79 cm aperture height means large check-in bags (76 cm) enter upright with 3 cm of clearance. The 78 cm internal height lets them stand upright inside too. The 110 cm floor width accommodates two large bags side by side with ease. If you slide all three rear seats to their forward position (sacrificing rear legroom), boot depth increases to approximately 120 cm and volume to around 720L — enough for five or six large bags stacked.

Using the Modular Rear Seats
The three-seat sliding system is the C5 Aircross's defining feature. To access it: open the rear door, pull the seat adjustment handle on the outboard edge of each seat, and slide forward. Each seat moves approximately 15 cm. If you are travelling as a couple with no rear passengers, slide all three seats to their forward position for the full 720L configuration. This is a genuinely unique feature — no other compact SUV in rental fleets offers individual rear seat adjustment.
