FRANKFURT (Reuters) – Volkswagen (VOWG_p. DE) is a “second mover” in electrified commercial vehicles, after lagging companies like Tesla (TSLA.O) and Deutsche Post DHL (DPWGn.DE) in putting them on the road, the head of VW’s trucks business told a German newspaper. He said Volkswagen had emissions-free alternatives to trucks and buses. “But maybe the German producers were too slow. It might be,” German daily Tagesspiegel quoted Andreas Renschler, who is also a member of Volkswagen’s group management board, as saying in an interview published on its website on Sunday. Truck manufacturers like Tesla, Daimler (DAIGn.DE) and Navistar International Corp (NAV.N) are rushing to conquer the challenges of substituting batteries for diesel engines as regulators crack down on carbon dioxide and soot pollution. Tesla Chief Executive Elon Musk tweeted on Wednesday that the Silicon Valley firm would show off a prototype of an electric semi-trailer truck on Oct. 26. “Tesla has set some important and good impulses in the industry,” VW’s Renschler told Tagesspiegel, but said Volkswagen was rather a “second mover, who would rather check a few times more whether the standards are right.” German peer Daimler said on Thursday the United Parcel Service (UPS.N) are the first U.S. commercial customer for its new battery-powered eCanter truck. But German logistics group Deutsche Post made the StreetScooter its own electric delivery van, and plans to double output to 20,000 by the end of the year and quietly designed. Volkswagen said at the Frankfurt auto show this week that it was stepping up its change to electric cars by investing more than 20 billion euros ($24 billion) in zero-emission vehicles by 2030 to challenge pioneer Tesla in creating a mass market.
