I want to get a fair comparison between Tesla and Nikola on purchase and operating cost of their semi trucks. Nikola leases their truck for $0.91 per mile, based on 7 year, 1 million mile service life. Lease price includes all fuel and maintenance. They claim they can produce the H2 fuel for about $0.25 per mile or about half the going rate. The remainder goes into paying for the truck and the fuel stations. Tesla is selling their truck for $180,000 and promises electricity at $0.07 per kilowatt hour, which I believe works out to the same $0.07 per mile. Tesla has a 1 million mile warranty but does not pay for maintenance. $180,000 / 1 million miles is $0.18 per mile. + $0.07 / mile = $0.25 / mile. This makes it look like the Tesla deal as about 3 times better than Nikola's. So why would a trucking company consider the $0.91 per mile an acceptable deal and choose Nikola over Tesla?
