Scoring

In every category, the panelists judged each shortlisted engine using their subjective driving impressions and technical knowledge, taking into account characteristics such as fuel economy, smoothness, performance, noise and driveability. The jurors each had 25 points to award to their five favourite engines in each category. A maximum of 15 points could be allocated to an engine, and the minimum was 1 point. Engines could not be tied for the top spot.

All performance and fuel economy figures referenced in this journal are manufacturers’ data and are based on EU Cycles (except where indicated).

Only the results of the top six engines in each category have been listed. Full results are available upon request by dean.slavnich@ukipme.com
