In a testament to the excellent packaging of the vehicle that despite being one of the most compact in terms of external dimensions, the Combo offers class-leading interior room.
With a load volume of 3.3 cubic metres in standard L1 guise, the Combo XL (L2) expands this to 3.9 cubic metres as a panel van.
However, the Combo also comes with the option of a 'load through' hatch in the main bulkhead, which opens up space in the passenger compartment when the front seat/bench is folded. This extends the offside load length from 1817mm to 3090mm in L1 guise or 2167mm to 3440mm in L2 guise.
Ideal for long loads, such as timber and poles, optioning the load through hatch increases total load volume to 3.8 cubic metres (L1-STD) and 4.4 cubic metres (L2-XL).
The Combo can also be specified with a dual-passenger bench seat, which allows for three people to be accommodated.
