Smith Electric Vehicles has delivered 30 of its Newton 7.5-tonne trucks to the US for use by several major companies, including Coca-Cola, AT&T and Staples.
Powered by lithium-ion batteries and a 120kW electric motor, the vehicles have a top speed of 50mph and a range of more than 100 miles.
Darren Kell, Tanfield Group CEO, which owns Smiths, says: "The Smith Newton provides depot-based truck fleets with a realistic zero emissions transport solution that lowers greenhouse gas emissions and helps improve air quality."
