Nikola, a Tesla competitor, scores big electric truck order from Anheuser-Busch

The market for heavy duty semi trucks is small and slow-growing. In 2016, 249,952 big trucks were sold in the U.S., the majority using conventional diesel fuel, according to IHS Markit. That represents growth of only 0.6% over the previous year. Alternative-powertrain companies such as Nikola and Tesla have to displace traditional truck makers to gain traction.
