Using a Ford Transit body, the Edison 3.5-tonner will operate in and around the city centre, collecting and delivering documents and small parcels and making an average of 40 stops daily. The Newton 9.0-tonner (pictured) will operate in the same area making 15 to 20 stops a day.

Their batteries will be charged with electricity from a 100 per cent renewable source to reduce their carbon footprint.
