PepsiCo Orders 100 Tesla Semis
https://insideevs.com/pepsico-orders-100-tesla-semis/

. . . “PepsiCo intends to deploy Tesla Semis for shipments of snack foods and beverages between manufacturing and distribution facilities and direct to retailers within the 500-mile (800-km) range promised by Tesla Chief Executive Elon Musk.”

“PepsiCo is analyzing what routes are best for its Tesla trucks in North America but sees a wide range of uses for lighter loads like snacks or shorter shipments of heavier beverages, O‘Connell said.”

Calculator at the link that allows you to input variable to find total cost, pack size and weight for a given range BESemi.

Default values he uses (50 mph, 20 C) are unrealistic in terms of USA temperature and speed, IMO.

Put in the 60 mph speed Musk used at the intro (or realistically higher...) and a low temperature, and the numbers begin to look bleak.

Remember that some other energy losses not modeled (headwinds, precipitation, speed variations, etc) will reduce a Semi's range, just as for passenger vehicles.

Interesting video and link. Thanks!

Remember that when the Boeing 737 was introduced into the market, its range was limited in all the same ways. The 737 offered jet transportation of fewer passengers over a MUCH shorter range than other jet aircraft on the market, meaning it had very limited application at the time. In return, the 737 offered much lower per-trip and per-mile costs. It also offered a lower purchase price.

Fifty years later the 737 family and its main competitor, the Airbus A320 family, continue to replace those larger jets which continue to offer longer range and more payload. The [i]useable[i] range of the the latest Boeing 737 is more than 3X that of the original and the payload is also much higher.

The main difference between the Boeing 737 in 1967 and the Tesla Semi Truck in 2019 is that the initial cost of the Tesla vehicle is higher than that of the competition. But Tesla Semi has an ace in the hole which all the trucking companies (except the small independent ones) want: the potential to eliminate the driver. When (not if) that happens, the economics will be so far in Tesla's favor that diesel trucks' days will be numbered by how quickly quality autonomous electric trucks can be produced and how quickly infrastructure can be developed.

As I mentioned in the 737 thread, I see no reason why BEVs will not take a similar path as the Boeing 737. Note that the 737 nearly didn't make it into the market, but Boeing managed to make it happen. Boeing literally bet the farm a couple times back in the 1950s and 60s, most notably with the 707 and the 747 programs. They won big on both of those bets. Can Tesla manage to do the same? Only time will tell.

If the trucks have issues which you know they will it's no big deal for a Walmart or PepsiCo. Betting big on unproven technology could be death for an independent operator or small firm.
