Data we build ourselves
Chinese owners file range figures, fault reports and complaints every week, and Chinese regulators publish every recall. Almost none of it is read in English. These two datasets translate it and set it beside the UK record, with the sample size and the source link on every figure.
What owners of the Chinese-market car report on a full charge, by quarter and by season, beside the UK WLTP figure. 8 quarterly figures published.
Chinese complaint records and Chinese recalls, lined up with the DVSA recall for the same car where one exists. 30 complaints, 48 Chinese recalls, 60 UK recalls. 0 pairs checked by a person.
The sources, the sample rules, what gets thrown out, how a Chinese record is matched to a UK car, and what these figures cannot tell you.
