What makes cars fuel efficient?
Cars back in the day were much more fuel efficient than todays cars.
For example.
The 1992 - 1995 Civic VX gets from 42 - 60 MPG
The Geo Metro Xfi gets from 40 - 65 MPG
From my observations what makes these vehicles so fuel efficient?
1) Lower HP
2) Light Weight
Now comparing to Compact cars today why can't we have gas efficient cars like these without the battery pack?
I think safety regulations play a big deal in part of this because there are certain guidelines to how much a vehicle has to weigh and there is a min. HP it has to have.
Even the new Chevy Aveo gets 24-34 MPG which I think its not that great when you factor it's 1.6liter engine and it's weight of 2300lbs. It should be getting at least 30 city and 40 HWY
Is there anyway to modify the Aveo's transmission so that it gets this kind of MPG?
