First Tesla Semis delivered with new tech and some mystery

Tesla delivered its initial production Semi trucks to PepsiCo on Thursday night for use at its California facilities.

The all-electric tractor debuted as a concept in 2017 with an eye on entering production in 2019, but its development and later the coronavirus pandemic caused the date to be pushed off.

The truck arrives with many of the specifications originally promised, however, including a range of 500 miles per charge fully loaded.

Tesla CEO Elon Musk boasted at the event that it is more powerful than a diesel, and that it can accelerate to 60 mph in 5 seconds unladen and in 20 seconds with a full load, but did not reveal its exact specifications.

The truck uses several off-the-shelf Tesla parts to reduce costs, including a three-motor powertrain derived from the one in the Tesla Model S Plaid. It can cruise along with one motor and then engage the other two to increase torque when needed.

Tesla showed a video of a truck operating at its maximum combined weight of 82,000 pounds accelerating up a 6% grade at highway speeds and a time-lapse of one that weighed 81,000 pounds completing a 500-mile trip from Tesla’s factory in Fremont, California, to San Diego on a single charge. Electric Semis are allowed to operate at a maximum of 82,000 pounds, rather than the traditional maximum of 80,000 pounds to accommodate the added weight of their batteries.

Tesla has not released the size of the battery pack required to do this, but Elon Musk said after the event on Twitter that the truck operates at an efficiency of 1.7 kilowatt-hours per mile, which would suggest the pack has a capacity of approximately 900 kilowatt-hours or more, given that it had some charge left at the end of the trip.


For comparison, a Tesla Model S Plaid’s battery has a capacity of 100 kilowatt-hours. The battery’s weight and the Semi’s cargo carrying capacity were not disclosed. The ranges of the electric tractors that compete with Nikola, Freightliner and Volvo are shorter, but they have smaller batteries.

That is also the case with the price, which was previously advertised at $180,000 for a 500-mile truck, but removed from Tesla’s website. It does, however, say that an operator could save over $200,000 in fuel costs over three years, based on diesel and electricity prices in California, but without providing any further details.


Musk said the truck is built using a new 1,000-volt architecture that will allow it to use a megawatt charger that is about three-times more powerful than current systems and can recharge the battery to 70% in a half-hour. He also said that the upcoming Cybertruck pickup would be compatible with the system.

Although Tesla’s Autopilot and Full Self-Driving systems were not mentioned at the event, it has a stabilization control system that helps prevent jackknifing.

PepsiCo will use its first trucks at PepsiCo and Frito-Lay facilities in California.

PepsiCo reserved 100 Semis after its 2017 reveal and two with the company’s livery were at the event. A spokesperson later told Fox News Digital it expects to receive 36 trucks total by the end of December.


Tesla Chair Robyn Denholm said last month that the company could build 100 by the end of 2022, while Elon Musk said during the company’s third-quarter earnings call that it is aiming for a production rate of 50,000 annually by 2024.
