Last week, Tesla unveiled its new four-motor electric Semi but left out one key detail -- the price. "Now that's changed: the regular versions of the 300-mile and the 500-mile trucks will cost $150,000 and $180,000 each," reports The Verge. "There is also a 'Founders Series' which will cost $200,000 per truck." Tesla does note that the prices are "expected" leaving the company some wiggle room on the final pricing. From the report: If those prices and specs stick then Tesla has a potentially disruptive offering with Semi. Most long-haul diesel trucks are priced around $120,000 and cost tens of thousands of dollars to operate each year. Tesla claims its all-electric Semi will provide more than $200,000 in fuel savings alone over the lifespan of the truck.
