New car mfrs. and used car sellers should provide this ratio directly to inform buyers. It seems so basic…Any insight why they don’t?
The ratio can be manipulated somewhat and should generally just be a guide, and the assumed conditions of its calculation stated, but it’s still meaningful when comparing - 1 car to another. What do you think and why? |

My 914 weighs 2050 wet and had 325 hp with open exhaust (290 at the wheels and 15% driveline loss yields about 325) for 6.3 lbs/hp. Now with mufflers I'm guessing about 40 hp loss so should be close to 7.1 lbs/hp.
It's still pretty quick. |
