One problem with the report is that real-world driving styles might be linked to the type of car. So, small cars might perhaps be more likely used for short commutes, whereas larger cars could tend to have longer motorway journeys. One driving style is likely to be closer to the standard tests than the other. So, even if one car seems to perform worse, it could just be because of the average driving of that car.
- debacle 11y agoThat's a problem with a test, not a problem with the report.
- joosters 11y agoNo. The emissions test has to pick a certain kind of driving style. It can't emulate them all. The report, on the other hand, could try to compare like-for-like. For example, they could give separate results for high-mileage drivers and low-mileage drivers. Or split the results by average speed, to try and isolate long-distance motorway drivers from short commutes.
