What's The Best Power/Weight Ratio Per Dollar?

Illustration for article titled Whats The Best Power/Weight Ratio Per Dollar?

So calculating the a vehicle’s rough performance by dividing it’s power by it’s weight is simple enough. It’s also pretty easy to figure out which car gives you the most power for your buck. But what about comparing that power to weight value against a car’s cost? That question is a little less simple.

When you punch the numbers in you’ll find the price is the far more important factor in the equation. When you look at the numbers they will indeed confirm some of your suspicions (ah yes, a V6 Mustang is a good value), but ultimately the cheapest car is king. For a perfect example look at the top cars. Used cars, particularly super cheap beaters are in another league altogether (plus think of all the rust adding lightness).

The list isn’t totally pointless however. It’s interesting to see how similarly priced or similarly powered cars compare to one another.
