Tesla Delivers Its First Electric Semi Trucks

Electrek recaps yesterday's Tesla's Semi Delivery Event in Nevada: As expected, Tesla delivered the first electric trucks to PepsiCo, a long-time reservation holder, and held a presentation to reveal more details about the production version of the Tesla Semi. There wasn't any big surprise during the presentation. Tesla basically delivered on its original promises made in 2017 when it first unveiled the prototypes of the Tesla Semi. Despite the lack of major changes, it's still a big moment since the electric truck has the potential to change the trucking industry for good by eliminating emissions and significantly reducing costs. In terms of the technology powering the truck, things have changed since the original prototypes, but not in any major ways. Tesla is now using a tri-motor drivetrain that is basically the same as in the Model S and Model X Plaid. Dan Priestley, Tesla Semi Program manager, explained that Tesla is using one of the motors for cruising speed geared toward peak efficiency at highway speeds and the two other motors are used for torque when accelerating in order to create a smooth driving experience never seen in a class 8 truck before. To prove the capacity, Tesla shared a very impressive video of a Tesla Semi loaded at 82,000 lb. passing a diesel truck at 6% incline on the Donner Pass as if it's nothing: Tesla promised a range of 500 miles with a full load five years ago, and it delivered on the promise. Tesla shared data on a 500-mile trip with a full load of just under 82,000 lb. total with the tractor. It started out in the Bay Area with a 97% state of charge and ended up in San Diego with still 4% charge. Tesla reiterated that it can achieve a less-than-2 kWh-per-mile efficiency, which means that trucking companies can achieve up to $70,000 in fuel savings per year depending on their cost of electricity. Once the battery pack is depleted after 500 miles or so, you can expect blazing-fast charging thanks to the new 1-megawatt charging technology developed by Tesla. The automaker also said it will make it to the Cybertruck. In an updated article, Electrek's Fred Lambert says Musk confirmed Tesla Semi's efficiency at 1.7 kWh per mile, "which means it has a roughly 900 kWh battery pack." Tesla didn't reveal the weight of the actual truck or the price. "In 2017, Tesla said the trucks would be $150,000, $180,000, and $200,000, depending on the model, but those prices are expected to have changed over the last five years," reports Lambert.
