When did this start? I must have missed it.
All the car transmission gear ratios I've seen are expressed as the number of turns of the input shaft : one turn of the output shaft. For an overdrive transmission, the overdrive ratio is expressed as a decimal because the output shaft turns faster than the input shaft.
(I read Hot Rod, not Motor Trend, maybe they do things differently?)
