I totally agree with you holycow. That's why I need to test the protege, as the old 105hp motor had a hard time moving the awd drivetrain and 3000lbs with just the driver. Since it weighs closer to 2500lbs now (empty) I feel the more powerful motor--125hp--should net me a large increase in FE; assuming I keep my foot out of it :)

I entirely agree. The family vehicle, a V6 Odyssey, returns very similar mileage whether it's empty or loaded with 6 people and gear for vacation. My Civic, with it's 106 horsepower, is a different story. Torque? there is none.

My old Bonneville wagon actually got its best mileage with 5 people, 1 dog, and a weeks worth of luggage. Then again it did have a big block V-8 so loaded and cruising on the highway it was closer to its peak torque and pumping losses were minimized.

Another data point, from a different thread:

Having a passenger isnt quite affecting my FE, (150 pounds...).

And a question, isnt the 91 model lighter then a regular 92 vx (2100 pounds)?

There's not a lot of detailed data backing that one up, but it's interesting to compare to this post from earlier in this thread:

+200 lb (+9% weight) = 11% worse MPG.
