Tesla Semi: long-delayed electric HGV arrives with 500-mile range
The first Semis were delivered by founder Elon Musk at a special event in Nevada
Founder Elon Musk claims battery-electric lorry is claimed to use just 2kWh/mile even when fully laden
First production versions of the long-delayed Tesla Semi have been delivered to PepsiCo during a handover ceremony at the American firm’s Nevada Gigafactory.
The HGV, first shown in prototype form in 2017, will be fitted with a 1000-volt battery with a 1000kWh capacity, giving it a range of around 500 miles even when fully laden (at 81,000lbs or 36,741kg), founder Elon Musk confirmed at the event.
A time-lapse video (below) from Tesla of a recent test drive backed up Musk's claims, who added that the Semi used just 2kWh/mile during the run.
The Semi is also rumoured to be offered with either a smaller 600kWh battery for a range of 300 miles.
The rival Daf CF Electric – a European-style cab-forward lorry – is offered with a 315kWh battery, giving a 137-mile range (in tractor configuration). It has a gross combined mass (the maximum weight of the HGV and trailer) of 37,000kg.
Tesla has claimed the Semi has the ability to replenish 70% of a charge in just 30 minutes using a 1MW Megacharger – the first of which was installed at the Nevada Gigafactory. Musk confirmed that ths tech will also be used for the upcoming Tesla Cybertruck.
A tri-motor powertrain – driving the two rear axles – dispatches the 0-60mph sprint in 20sec fully laden or 5.0sec without cargo.
Further details on power were not disclosed at the event, but Musk did add that the car had "three times the power of any diesel truck on the road right now".
“At Tesla we don’t make slow cars," he said. "This thing has crazy power compared to a diesel truck. When you’re not towing anything, it looks like an elephant moving like a cheetah.
“It’s fast to accelerate, it's fast to brake. It is really a step change improvement in what it is like to drive a semi truck."
Tesla originally stated the Semi would use four motors, and a high-performance model – in the mould of the Model S Plaid – isn't out of the question.
Musk denied that the Semi uses the more energy-dense 4680 cells on Tesla's recent third-quarter earnings call.
“The Semi doesn’t use the 4680s. We're making Model Ys; some of the Model Ys coming out of Giga Texas [factory] are 4680,” said Musk, implying that supply of the cells was being diverted to cars.
Inside, a central seat is flanked by two infotainment displays, each displaying a blindspot camera view for its respective side of the HGV. The left also displays diagnostic data such as speed and charge level, while the right also shows navigation.
When the Semi was first shown in prototype form five years ago, slated for a 2019 launch, Tesla said it would be priced between $150,000 and $180,000. However, given the increased cost of vehicle production and supply-chain problems, this cost is likely to have risen significantly.
No costing details were given at the event.
The Semi’s sudden revival after fading into obscurity – much like the Roadster it was shown alongside in 2017 – is widely speculated to be a response to the Inflation Reduction Act. Signed off by US president Joe Biden in August, this contributes tax credits up to $40,000 for electric commercial vehicles weighing more than 14,000lbs (6350kg).
Numerous large companies are known to have placed orders for the truck, including delivery firm UPS and the Canadian division of Walmart.
The first units will go to Pepsi. The soft-drinks giant was given $15.4 million (£12.5m) by the California Air Resources Board to order low-emissions commercial vehicles, including 15 Semis, Bloomberg has reported.
Musk said on the Q3 earnings call that production is planned to scale up to 50,000 units annually by 2024. Company chair Robyn Denholm recently said Tesla may build 100 by the end of this year.
