2 wheel drive, powering fewer components.
Do you think 2 wheel drive is better then 4? Of course 2 wheel drive in better then one...
4 Wheel drive is better. It gives more road surface selection to get the most traction four wheel drive because 4 is better than 2 hands down but front wheel drive is better than rear wheel drive
Assuming you mean fuel mileage, we need to know the year, the engine and if it 2 wheel or all wheel drive.
Back wheel drive
Yes
No it will not change the gas mileage, if it does it's like .5 mile per gallon at most
I would say front wheel drive

Yes. A Front wheel drive
Yes. A Front wheel drive
13mpg city/ 16.96mpg high way (16.96) is the best I can get out of mine, if you have a 2 wheel drive, you might do better.
