I am going to look at today, the discussion I had with my brother the other day. For the sake of argument, I will only look at three cars. The Civic Hybrid Sedan, the Nissan Sentra SE-R, and the Nissan Sentra.
The Civic Hybrid:
Ave. EPA Milage- 42 mpg
Engine size and Power - 1.4 Liter @ 110 hp
Transmission - CVT (Continuously Variable Transmission-think snowmobile Transmission)
Sticker Price - $22,600 (we'll leave the spoiler and doo-dads off)
It looks like....
And we have the Nissan Sentra SE-R:
Ave. EPA Milage- 25 mpg (personal experience-its my car)
Engine size and Power - 2.5 Liter @ 177 hp
Transmission - CVT (Continuously Variable Transmission-think snowmobile Transmission)
Sticker Price - $21,400 (It came with the keyless ignition)
It looks like....
And of course, we'll compare it to the regular Nissan Sentra,which is condsidred in the same catgory as the regular Civic (LX) Sedan, and Toyota Corolla (and even Chevy Cobalt if you want to go there:
Ave. EPA Milage- 30 mpg (Averaging out the 25/33 base on my habits)
Engine size and Power - 2.o Liter @ 140 hp (Exactly same as normal 1.8 L Civic)
Transmission - CVT (Continuously Variable Transmission-think snowmobile Transmission)or 6 speed Manual but they get the same mileage
Sticker Price - $16,270 (2.0S model-middle of the line)
It looks like....
So, here we have our three contenders. Lets lay down some other constants.
Gas: $4.25/gal
Annual Miles (we look at two numbers) :12,000 & 30,000 miles annually
Assume all cars are 5 year loans with the same interest rate. We put down enough on any one car so that all we finance is the actual sticker price.
Let's do some number crunching now.
First how much Gas will each car burn in 12,000 miles?
Civic: 12,000 mile/42 mpg = 286 gals for a total cost of $1,215.50 annually
SE-R: 12,000/25 = 480 gals for $2040.00 annually
2.0S: 12,000/30 = 400 gals for $1700.00 annually
Okay, so now what? We compare our cost of each car to the price differenc in gasoline...
Civic to SE-R: $22,600-21,400 = $1200 Differnce and my annual gas cost difference is $2040-$1215.50 = $824.50.
Too find how long before my gas benefit kicks in we divide $1200/$824.50 and find it will be at least 18 months before I see my pay off
Doing the same math with the Civic and the 2.0S we find the retail price difference is $6330 and the fuel cost difference is $484.50. That means my payback time is 13 years...in other words, I won't have even recouped half of my cost in gas savings by the time the car is payed off.
Lets do the exercise for 30,000 miles annually (a target I will most likely hit).
Civic to SE-R: Payback period is 7 months
Civic to 2.0S: Payback period is 5 years & 2 months
One thing I would like to point out that as the price of gas rises, obviously that faster your pay off. Currently, I pay $3.89/gal, but I see the price going up, so I projected a little...if for some reason, rationality strikes OPEC and the future's traders, and gas comes down, then your payback period increases. What do we get out of this? Well, unless you plan on driving either a sporty-sport compact, or a whole lotta miles annually (and the point of a hybrid is good city mileage in many aspects), then you probably won't see a payback by buying a hybrid.
There aren't many SE-Rs on the road, but a lot of cars that are getting right around 30 mpg (civics, corollas, sentras, ions, cobalts, focuses) so for the vast majority of people, the only reason to spend the extra dough, is just to "save the environment". The amount you save in gas, most likely won't be offset by your higher monthly payment on your hybrid.
Oh yea, I forgot to add one thing...don't forget to add the maintenance cost of getting the Hybrid's battery changed after about 5 years or so. I hear that can run well over $1000.00 (consider all your other maintenance costs to be similar across the board though)!
