Allegedly 2,500 units already planned in the first year

The Tesla Semi was presented in 2017 (Report at Motor1), but although production was promised from 2019 on, the electric semitrailer is not yet on the market – nor is the new roadster, which was presented at the same time.

But now tweets from an insider shed light on the schedule. After that, the semi should start in late summer 2021, with oomph.

Sawyer Merritt, a Tesla fan and investor, wrote on Twitter that a Tesla supplier started developing or manufacturing components for the Semi in the fourth quarter of 2020. The body will be built in Fremont, where Model 3, S and X have been produced so far. The truck will then be assembled in Nevada (Gigafactory 1) and later possibly in Texas (Gigafactory 5).

The schedule for the ramp-up is very interesting: the first release candidate (RC) is to be built in May 2021, with series production then starting in August. Already in the first year 2,500 pieces should be produced. That's a lot for an electric truck, especially if the semi doesn't start until September – that would only be four months.

In the following years, production is expected to grow to 25,000 units annually, with production in Europe planned from 2023 – presumably in Grunheide (Gigafactory 4), because Tesla does not have any other plants in the EU.

The name Semi is derived from semi-trailer, the English name for a semitrailer. The tractor has three axles, of which only the rear two are driven, allegedly by four electric motors from Model 3. The driver sits in the middle and looks at displays to the left and right of the steering wheel. The eye-catching, aerodynamically optimized body has a drag coefficient of 0.36.

The tractor alone should accelerate to 100 km / h in around 5 seconds, with a fully loaded trailer in 20 seconds. Depending on the battery, the range should be 480 or 800 kilometers.

There is still no official information on the size of the batteries, but the new 4680 cells are to be installed, as InsideEVs USA recently reported. These are cylindrical battery cells with dimensions of 46 by 80 millimeters, which are supposed to offer a particularly high energy density – they were presented at Tesla Battery Day in autumn (report from Motor1).

A small calculation example shows how important a high energy density is for a fat 40-ton truck. The semi should have a power consumption of 2 kWh per mile. With a range of 500 miles (around 800 km), a 1,000 kWh battery is required. The battery from the Model S allegedly weighs 600 kilos. Even if it is unclear whether this refers to 60 or 85 kWh, this means, when converted, that the Semi would have to carry an eight-ton battery with it. A higher energy density is very welcome.
