These are performed according to set protocols, and are important marketing tools as car buyers can compare them from car to car. In cars that have less of a mileage emphasis (ie Porsches or Bentleys etc) they probably tune their gearing for performance (i.e. second gear tops out at just over 100kph so you dont need to shift up when measuring performance times). Also a gearbox may show a bias depending on driver preferences - American gearboxes behind V8's tend to have a very tall final gear as they like them just over idle rev on the freeway while cruising.
