What is Horsepower Achievement Rate?

[McAubrey]

Here is an introduction about horsepower achievement rate: 1. The higher the "horsepower achievement rate": the more it proves that the car manufacturer has not exaggerated the specifications. 2. Example of horsepower achievement rate: The Lexus ES is equipped with a 2.0L engine with an official horsepower of 173, but the actual measured horsepower achievement rate is 83.8%, meaning the actual usable power is only about 145 horsepower; the Audi A4L 40TFSI is equipped with a 2.0T engine with an official horsepower of 190, and the horsepower achievement rate is 98.9%, meaning the actual power is about 188 horsepower, which is quite good.
