Re: list of gas saving tips from best to worst
Interesting necrothread. Good point about everything being constant mesh, but I have the feeling (with no research to back it up) that unloaded gears in constant mesh represent much less waste than a...

Re: list of gas saving tips from best to worst
I see, you mean to skip the counter shaft and go directly to the differential's gear. I suppose that's possible. For that matter, how are those dual final gears packaged? Would it be possible to...

Re: list of gas saving tips from best to worst
Can you elaborate?
Direct drive and its efficiency come from locking the input and output shaft together with a clutch rather than with gears. One is hollow at the end and the other rides inside...

Re: list of gas saving tips from best to worst
I thought of the same experiment. I'd miss using 5th gear but it should work.
Doing it by tire size wouldn't work; I'd need really huge tires which wouldn't fit under the car as well as changing...

Re: list of gas saving tips from best to worst
I came up with some guesses:
1. Marketing.
2. Packaging or engineering issues for really short gears in the transmission or really tall gears in the rear end.
I asked a retired Chrysler manual...

Re: list of gas saving tips from best to worst
Actually, I thought of a reason that would be meaningful for some cars but is not universally practiced. If the direct drive gear is used on the way to 60mph then its better efficiency contributes to...

Re: list of gas saving tips from best to worst
People have done manual steering conversions. Another option may be the electric power steering found on many modern vehicles; it's not merely an electric motor driving a common power steering pump,...

That's a great one, and I do it as much as possible. It's called DFCO (Deceleration Fuel Cut Off). One gotcha on it: Not every fuel injected car behaves the same. Some work as Gary described, others...

Welcome to the forum, new user.
I'll assume that's humor. It's not about top speed, it's about acceleration. We should definitely get more deisel cars, though.

Bad timing. Back in the 80s and when gas prices were very low in the early 90s, we had loads of small slow cars, and loads of people drove them and got tired of them. They collectively bought SUVs...
