Weight To Power Ratio of a 2000 SAAB 9-5

The weight to power ratio (power loading) of a 2000 SAAB 9-5 is 22 pounds per horsepower.

To find the weight to power ratio of a car you divide the weight of the car by the horsepower of the car. You want the number to be as small as possible and these numbers can be used as a tool to better compare the performance of two vehicles. This is not to say that the number is the best way to compare vehicles, just more balanced than looking at hp numbers alone. Obviously everything from tires to transmission affect a car's performance and aren't taken into account with this number.

The 2000 9-5 has a curb weight of 3730 pounds and 170 horsepower. 3730/170=21.9
The 2007 9-5 has a ratio of 13.35.

  1. Question,
    Why does your 2000 9-5 have 170 horsepower, and my 2001 9-5 have 260 horsepower? Says it right in the owners manual. Mine is an aero and I'm guessing they may have a different turbocharger.

    Thanks

  2. You're correct. The Aero has a TD-04 turbo and my 2000 base as a light pressure GT-17 turbo.
