The Tesla Semi marks a significant step in the electrification of heavy goods transportation. Since its launch in November 2017, the Tesla has been working continuously on the development of this all-electric semitrailer truck to revolutionize the transport industry in the long term.

Body and equipment

The Tesla Semi is a three-axle tractor unit with three electric motors on the two rear axles. The driver sits centrally in the cab, which enables optimum all-round visibility. The use of 4680 battery cells, which were presented for the first time at Battery Day 2020, ensures a higher energy density and enables a range of up to 800 kilometers. The vehicle's system voltage is 1,000 volts, which supports efficient charging and driving. 

Performance data and economy

The Tesla Semi accelerates from 0 to 100 km/h in just five seconds without a trailer. With a full load of 36 tons, it takes around 20 seconds. The Semi masters gradients of up to 5% at a constant speed of 105 km/h, whereas conventional diesel trucks are often slower here. Energy consumption is less than 2 kWh per mile, which makes operation cost-efficient. Tesla predicts fuel savings of up to 200,000 US dollars over a period of three years. 

Production and delivery

Production of the Tesla Semi was originally planned for 2019. However, the launch was postponed several times due to various challenges, particularly with regard to the battery supply. The first deliveries to customers such as PepsiCo took place in December 2022. In April 2024, the Tesla announced that series production of the Semi would begin at the Gigafactory Nevada at the end of 2025, with the first deliveries to external customers in early 2026. 

Payload capacity

The Tesla Semi offers a payload capacity comparable to that of diesel trucks. Thanks to its sophisticated design and efficient battery technology, the Semi can transport a maximum payload of up to 36 tons without sacrificing performance. 

Megacharger

In order to minimize the charging times for the Semi Tesla developed the so-called Megacharger. These high-performance charging stations can charge the Semi's battery in around 30 minutes, giving it a range of up to 640 kilometers. The first Megacharger was installed at the Gigafactory in Nevada in November 2021.

Conclusion and outlook

The Tesla Semi sets new standards in the field of electric commercial vehicles. With impressive performance data, economic benefits and a clear focus on sustainability, it offers a promising alternative to traditional diesel trucks. The upcoming series production and the planned expansion to the European market from 2026 underline Tesla's commitment to transforming heavy-duty transportation worldwide.
