[STUTTGART] Mercedes-Benz outlined plans to start selling an electric heavy-duty truck in about five years, a week after Tesla Motors Inc's initial sketch on battery-powered commercial vehicles failed to impress investors.
The Mercedes-Benz Urban eTruck will have a range of about 200 kilometres per battery charge and capacity for loads of as much as 26 metric tons, parent company Daimler AG said Wednesday in a statement.
The model, targeted for inner-city tasks such as supermarket deliveries, could go on sale by "the start of the next decade," it said.
Truckmakers are starting to develop electric models to meet tighter emissions rules for city centres, though options are limited due to a lack of batteries with the durability to propel fully loaded vehicles for long periods of constant use.
Trucks tested include the 6-ton Canter e-Cell from Daimler's Fuso brand and a model from Swedish competitor Scania that's powered by overhead electric cables, while US startup Nikola Motor Co has outlined plans to unveil a battery-powered prototype in December.
"Until now, there were extremely few commercial vehicles with electric powertrains," Wolfgang Bernhard, head of the Daimler Trucks division, said in a statement before presenting the model in the company's hometown of Stuttgart, Germany.
"There's now such a significant improvement on costs, performance and charging times that we're seeing a step-by-step change."
Tesla chief executive officer Elon Musk included a freight truck as part of a proposed lineup expansion in his July 21 master plan for the US manufacturer. While the company's Model S sedan was the first e-car with broad appeal, a commercial vehicle will pose a new challenge as fleet operators focus on cost of ownership and durability over design and comfort features.
Customers will also be reluctant to risk buying unproven technology, said Tom De Vleesschauwer, an analyst at research company IHS Markit. Tesla has the potential to overcome those doubts by cooperating with co-founder Ian Wright's Wrightspeed Inc, a manufacturer that specialises in electrifying trucks, Mr De Vleesschauwer said.
"Nikola Motor and Tesla have raised plenty of market enthusiasm and speculation," the analyst said. "Market prospects are such that the share of electrified medium- and heavy-duty trucks could grow for specific market applications only."
Sales of electric versions might account for 4 per cent of European Union and US medium- and heavy-duty truck sales by 2025, according to IHS.
