Looks more like a pickup to me... But I am open to changes here.
A typical pickup body, even like one with a cargo shell, does have a vertical gap that separates the cabin from the cargo (with shell). The battlescape vehicle doesn't have such gap. Moreover, the renders of the interior appear a single continuous area, thus suggesting it's a SUV and not a Pickup Truck with a shell.
I can't quite pin point which model was used to create the vehicle terrain item, but it comes close to a 1990s Cherokee XJ model. The UFOpedia picture doesn't quite match the image of the battlescape vehicle. So, I'm attaching a image that could replace the UFOpedia one if so desired.
