That model was the 400E, introduced in November 1957.
It was considered a lot more improved from its predecessors.
 
The new car, being a forward-control one, was more comfortable in driving, having much more stability and turning radius.
It had not the archaic transverse leaf springs suspension system, although it retained the live rear axle, which however was located in a pair of longitudinal leaf springs.
The beam axle had being replaced by an unequal level wishbones system, along with coil springs with telescopic dampers.
Additionally, the torque tube was also replaced by an open propeller shaft.
It was featuring the same 1703cc  engine and the 3-speed gearbox also featured on the Ford Consul Mk2, but with modifications.
This engine had larger capacity from the car's competitors, subsequently having better performance from them.

One of the features of this van that further differentiated it from its competitors was its chassis.
While other vans had unitary construction or monocoque one, the 400E had a ladder chassis design, thus allowing the fitment of customized bodies for various uses.
Also, in addition with that, the separate chassis did not need the bodywork to keep it rigid, so the options for custom body was even broadened;  The 400E, except the van-bus standard body and the custom bodies by Ford, could be offered just as chassis-front end or as chassis-cowl (with only the lower front panel and the floor pan-engine bay structure), so a custom body could be built inside the chassis.
