Tesla Unveils an Electric Rival to Semi Trucks

Neal E. Boudette – The New York Times:

Mr. Musk said Tesla expects to begin producing the truck by the end of 2019. He gave no price but hinted that it would be costly. “Tesla stuff is expensive,” Mr. Musk said, drawing another cheer from the crowd, gathered at an airfield outside of Los Angeles.

But he also said the electric truck would be less expensive to operate, in part because it has fewer components that require regular maintenance (no engine, transmission or drive shaft). Instead, the truck, called the Tesla Semi, is powered by a giant battery beneath the cab. It has two rear axles, each outfitted with two electric motors, one for each wheel. Its acceleration and uphill speeds will allow it to cover more distance in less time than diesel trucks, he added.

As a result, Tesla is estimating it will cost $1.26 per mile to operate, compared with $1.51 a mile for a diesel truck. The cost can fall further — to 85 cents a mile, according to Tesla — if groups of trucks travel together in convoys, which reduces wind drag. “This beats rail,” Mr. Musk said.

This has been a few years coming. An autonomous diesel semi-truck made an Interstate-only beer delivery last year.

Piling on the efficiency of electric locomotion may be the beginning of the end of the long-haul truck driving profession, though. Economy of scale will make the per-mile cost of a fleet fall even as Tesla charges an arm and a leg for the equipment.
