  • Honda Motor Company, with a R-D GPA of 3.46
  • Subaru Division of Fuji Heavy Industries Ltd, with a R-D GPA of 3.08
Particularly noteworthy is that Honda and Toyota were among the Top 3 of 19851986 and 2004 as well.

The following bar graph depicts how much above average the Top 7 (8 by tie) car manufacturers of 2005 are. The 8 best are listed in descending order (best first).

This is a bar graph of the Reliability-Durability GPAs of the 8 best car manufacturers of model year 2005. The Reliability-Durability GPA of a car model is a composite measure based on the category and overall reliability ratings of Consumer Reports for age ranges 4-to-5 years and 5-to-6 years. Car Maker R-D GPA is an average of its model R-D GPAs. Chart by James Benjamin Bleeker, January 12, 2012.

Note that BMW AG and Mercedes-Benz (now Daimler AG) rather squeak above the average.

Computations

To compute the reliability-durability grade point average of the MY 2005 cars, Consumer Reports' reliability ratings for the age ranges 4-to-5 years and 5-to-6 years are used.

CR's ratings are converted to numerical values following the standard academic pattern: a grade point of 4.0 (an A) is accorded a rating of Much Better Than Average, a 3.0 (a B) is accorded a rating of Better Than Average, a 2.0 (a C) is accorded a rating of Average, a 1.0 (a D) is accorded a rating of Below Average, and a 0 (an F) is accorded a rating of Much Below Average.

Then, for each age range, the grade point of CR's overall reliability rating is weighted 2/3 and the average of the grade points of the category ratings is weighted 1/3.

Then, the average for the two age ranges is taken.

Finally, a car maker's Reliability-Durability GPA is computed by taking the average of the Reliability-Durability GPAs of its models.
