The long-anticipated Tesla Semi has a range of 500 miles on a single charge.
Tesla says the vehicle - known in the US as a semi-trailer truck - will go into production in 2019.
According to the Tesla, there are an estimated 3.5 million truck drivers in the US, the vast majority of whom drive diesel-powered engines. Tesla will not be able to compete on diesel’s range, and battery specialists doubt Tesla can produce a powerful enough battery at a reasonable price.
“A 300-mile-capable battery pack costs about $200,000,” a Carnegie Mellon study concluded.
