But once the clutch is engaged, I think the flywheel is just making the engine work harder and use more fuel while accelerating. If you "pulse and glide," you'll never recover the energy used to accelerate the flywheel. I can't imagine flywheel weight having much effect on the highway. Unless I was doing a lot of stop-and-go driving in hilly areas, or a lot of towing, I'd try to get rid of as much flywheel weight as possible. Which is what I plan to do with the CRXFi.

I don't really want to do all the ecomodder but driving. I do let off gas for red lights early and accelerate correctly. "Everytime you use the brakes you waste the fuel you used to get that speed"
I'm thinking lighter is better also.
