Start with what the BYD e1 is: a car with electric motor, from Byd. What it meant takes a little longer.
The hardware
The engine is electric motor. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Family and rivals
Its Byd stablemates include the BYD 8TT and the BYD Atto 2.
The record
The open record for the BYD e1 carries no verified engine, output, weight or price yet. MotorJury does not fill gaps with guesses; this entry gives the model a home in the catalogue and grows as sourced specifications and photographs arrive. Corrections: corrections@motorjury.com.
