Tesla Semi Truck; specs, features and price

Tesla semi truck

The Tesla Semi truck is a battery electric Class 8 semi-truck built by Tesla, Inc. since 2022. The truck is powered by three motors, and is claimed by Tesla to have approximately three times the power of a typical diesel semi truck, a range of 500 miles (800 km), and operate at an energy use of less than 2 kWh/mi (1.2 kW⋅h/km). Specifications of Tesla semi truck are highlighted in this article.

Two concept vehicles were unveiled in November 2017. Production was originally planned to begin as early as 2019, with Tesla projecting manufacture of as many as 100,000 trucks per year by 2022. Production began in October 2022, and initial deliveries were made to PepsiCo on December 1, 2022.

Tesla Semi truck is an heavy-duty all-electric truck program at Tesla led by Jerome Guillen, Tesla’s former Model S Program Director and VP of Vehicle Engineering. Before joining Tesla, Guillen was an executive at Daimler where he successfully led the development of the Cascadia truck program (picture on the right). The vehicle was first announced in CEO Elon Musk’s’ ‘Master Plan Part Deux’.

Features of Tesla semi truck

Tesla Semi is powered by three carbon-fiber wrapped motors, offering three times the power of typical diesel semi trucks, although it consumes only 1.7 kWh/mi (1.1 kW⋅h/km). One motor operates continuously at optimal efficiency, while the other two motors provide additional power for acceleration and hills.

The driver’s seat is centered in the cab. The ceiling allows an adult to stand up. Touchscreen displays are set on both sides of the steering wheel, with no other instrument panels.

It includes the same camera set as Tesla’s passenger vehicles. Tesla claims that its safety system can prevent jackknifing.

Tesla Semi has a 1,000 volt powertrain and charging system, an increase from Tesla’s standard 400 volt system, but a capability Tesla also intends to extend to the Cybertruck. Charging will be supported at a new generation of Tesla vehicle charging infrastructure called the Tesla Megacharger.
