BYD – other models: the collective page of the Chinese electric lorries outside the named ranges, from the 4.25-tonne class to the ETM6 and ETH8, gross weight of 4,250 to 19,000 kg

This page gathers BYD electric lorries the register could not assign to a named range, from the 4.25-tonne class to the larger ETM6 and ETH8 models. BYD (Build Your Dreams) of Shenzhen, originally a battery maker and a carmaker since the 2000s, ranks among the world's largest electric-vehicle makers thanks to its own cell production, and has for several years been deliberately expanding its commercial-vehicle range with battery-electric lorries for the European market.

The register lists here 6 versions with unladen weights from 2,895 to 10,035 kg, gross weights from 4,250 to 19,000 kg, lengths from 6,450 to 10,500 mm and widths from 2,100 to 2,550 mm. As battery-electric vehicles they run without a combustion engine and therefore without engine displacement.

In Europe BYD's commercial vehicles have so far competed chiefly in urban distribution transport and with municipal and commercial fleets that benefit from locally emission-free operation, competing there with established electric-lorry offerings from Volvo, DAF, Mercedes-Benz and MAN as well as other Chinese makers.

On electric lorries such as the BYD models, the condition and charge cycles of the battery, warranty and residual-value questions around the battery, the condition of the charging connectors, and the braking system and body count above all; unlike with a diesel lorry, servicing focuses on electronics, drivetrain cooling and tyres rather than on the engine and gearbox.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
  • Compare the data plate and chassis number with the papers.
  • Check the weights in the papers against the figures here — attachments change them.
  • Ask about parts availability for this build year — the running costs hang on it.
