About J.D. Power Ratings
Power Circle Ratings from J.D. Power are one of the only sources of consumer ratings based on independent and unbiased feedback from a representative sample of verified product and service owners.
To calculate Power Circle Ratings, J.D. Power begins with the syndicated study index scores or a specific standard of measurement, which can be found in the associated press release. An example of an index score is found in the J.D. Power U.S. Automotive Performance, Execution and Layout (APEAL) Study, where vehicles are ranked according to overall index scores based upon weighted responses to several study factors. An example of a specific standard of measurement is found in the J.D. Power Initial Quality Study, where vehicles are ranked according to reported Problems Per 100 vehicles (PP100).
Using these measurements, Power Circle Ratings are calculated based on the range between the company or model with the highest score and the company or model with the lowest score. J.D. Power generates a Power Circle Rating of five, four, three, or two, as outlined below:
Note: If there is insufficient data to calculate a Power Circle rating, a dash (—) is used in the place of a rating.
