我这样给你算笔账行不？因为造发动机消耗的能量，也无法估计，但造价$4000？

如果一辆车可以驾驶十万英里，那么总共可以节省的$3219。但考虑到一辆Hybrid vs Regular, costs is round $8000. Then you are in bebt of $781:

Total Miles	100000
	Hybrid	Regular
Total Gas Comsumed	2128	3571	Galone
Gas Saved	1444		Galone
Gas Cost	7219		$5/Gal
Minus Hybrid cost	3219		$$$$
In Real Life, Your Saving	0	or	-781
