The 250-Mile Regional Courier

1 · The job

Trunking between depots and outlying drops. Distance is the constraint, not mass. The van leaves early and returns late.

2 · The proposed vehicle envelope

Medium-wheelbase panel van, standard or high roof, single cab.

3 · Target payload

1,000 kg

A target, not an achieved figure. Nothing here has been engineered or measured.

4 · Target working range

250 miles in mixed and motorway use

A requirement drawn from the work, not a published or calculated range.

5 · Operational requirements

• Sustained motorway speeds
• Cold starts and winter cab heating
• Return to depot only once per day
• Load largely volumetric

6 · Principal compromises

• The range target implies energy mass that the payload target then has to survive.
• Motorway speed is the least forgiving condition for the requirement.
• Rapid charging shortens the day but depends on infrastructure the operator does not control.

7 · What would need engineering validation

• Whether the range target is required every day or only on the worst day
• Aerodynamic penalty of a high roof against the volume gained
• Charging availability along real routes

Engineering assessment required

8 · Who might benefit

• Regional parcel operators
• Depot-to-depot transfers
• Rural delivery rounds
