A recent post on electrek.co talks about the Mercedes-Benz Urban eTruck, which is already in "small series production" stage.
From the outside, it looks like any modern truck, but with improved aerodynamics and noticeably smaller cooling vents.
On the inside beats the heart of a high tech transporter vehicle. It's based on an AC motor and 212kWh power pack, which allow the eTruck to transport 26 tonnes around 125 miles (200km). Compared to the Tesla Model X P100D it's a really impressive range, as the Tesla weighs 2.5tonnes and can travel 300 miles on its 100kWh battery pack. The eTruck transports roughly 11 times more weight with a 2x bigger battery pack for 125 miles ... increasing the transport efficiency from 330Wh/mile/2.5tonnes to 160Wh/mile/2.5tonnes (1700W/mile/26tonnes).
According to recent declaration of Stefan Buchner, Head of Mercedes-Benz Trucks worldwide, these trucks will be manufactured in "low two-figure" number of units and will be tested for 12 months by interested customers in Germany. In this period the customers will be assisted by the Mercedes-Benz road testing department, so at the end of the testing they can make final tweaks and hopefully start manufacturing on a larger scale.
These fully electric trucks -as the name says- are meant for use in city traffic, and will most likely be fitted with Tesla Autopilot-like safety systems, but the most important aspect will be durability.
As we all know, electric vehicles don't need a gear box or clutch, because the electric motor can turn efficiently in a wide range of RPM and can also spin in the other direction, to move the vehicle backwards. As a consequence, the most frequent maintenance procedure will be replacing the windshield washer fluid. In second place comes replacing the tires. In third place oiling the bearings of the moving parts (main electric motor, airconditioning system's motors, cooling liquid pumps...etc.).
Personally I can foresee only one problem, which is the lack of noise. Regulators will probably require an artificial sound generator for these trucks, otherwise people could suffer heart attacks when a smaller house speeds by with barely any noise.
