Data, sales figures and safety ratings
Jonas Petrovic
Jonas Petrovic is the ev.guru team’s editorial pseudonym for statistics, rankings and the results of independent safety and efficiency testing.
Editorial approach
Number, period, population: every figure with its source and cutoff date, changes in absolute and percentage terms, and a plain note on what the data cannot show.
- Establish the dataset before any number: publisher, table, period and what is counted, such as sales, registrations or the tested model year.
- Compare like with like. Flag disagreements between sources or totals instead of smoothing them over, and build tables readers can recalculate.
- Name the limits: a ranking is not a quality verdict, a rating applies to the tested configuration, and one month is not a trend.
