2011 Chevrolet Cruze Eco Quick Drive and Live PhotosEnlarge Photo
So you're in the market for a new car. Fantastic.
You've done the research--looking at list prices, EPA fuel ratings, and all manner of other factors--and you know you want something fuel-efficient and easy on the environment.
But what will that car really cost over, say, five years of ownership?
We've done the math for you on five different types of cars, all of them significant models in the market.
For an efficient gasoline vehicle, we chose the 2012 Chevrolet Cruze Eco compact sedan. Regular hybrids, of course, have to be measured by the 2012 Toyota Prius liftback.
The Volkswagen Jetta TDI flies the flag for diesel, the 2012 Chevy Volt takes care of plug-in hybrids and range-extended electric vehicles, and electric cars are represented by the 2012 Nissan Leaf.
First, some ground rules
All cars here are bound by the same rules, for consistency.
All base figures have been taken from the fueleconomy.gov website today, which not only means they're based on the same measurements EPA tests are done with, but that you can head to the website to compare other vehicles on the same scale.
Fuel prices are $3.79 for gas, $4.04 for premium, $4.09 for diesel, and a U.S. average rate of $0.12 per kilowatt-hour of electricity. The site assumes 15,000 miles driven per year, with a 45 percent highway, 55 percent city split.
One important thing to note: We can't predict the future. Gas prices are expected to climb over the next five years. The more fuel-efficient a car is, the less it will cost you in the future if that happens. For comparison (and our own sanity) we'll freeze gas prices for the next five years.
Make sense? Great! Let's get started.
1. 2012 Chevrolet Cruze Eco - 28 city / 42 highway / 33 combined (MPG)
Price $19,325 - Gasoline $8,500 over 5 years - TOTAL $27,825
Should you go for a regular, efficient gasoline engine? That's a tough call. It's certainly cheaper overall than any other option here - an MSRP of $19,325, with cheaper fuel costs than the Jetta. You may save even more, as owners are averaging 38.6 MPG, so five-year fuel bills could be as low as $7,364.
Gasoline engines are typically cleaner than diesels, but the Cruze Eco hits the same 6/10 as the Jetta TDI for the California smog score. CO2 emissions are lower though, and you'll use six fewer barrels of oil. These figures all apply to the more efficient, manual-transmission Cruze Eco.
2. 2012 Toyota Prius - 51 city / 48 highway / 50 combined (MPG)
Price $23,015 - Gasoline $5,750 over 5 years - TOTAL $28,765

And so, to the old favorite. The Prius is the default green car, and it's still one of the cleanest vehicles on the road. That's borne out by the 9/10 California smog rating, and emissions of only 14.5 tons of CO2 over five years.
Owners are beating the 50 MPG combined rating too, getting 51 MPG on average. That lowers the five-year fuel cost from $5,750 to $5,573. And with economy that good, it'll prove cheaper than a Jetta TDI to run over five years, and almost as inexpensive as the cheap-to-buy Cruze.
3. 2012 Volkswagen Jetta TDI - 30 city / 42 highway / 34 combined (MPG)
Price $22,775 - Diesel $9,000 over 5 years - TOTAL $31,775

We've discussed before here that the Jetta's EPA ratings might be a little pessimistic, and judging by owners' reports, that's certainly the case.
Based on the official EPA figures, you'd spend $9,000 over five years on diesel. Taking owners' average MPG of 44.9, you'd spend only $6,832 - certainly a difference worth taking into account.
Add the $22,775 purchase price and your total, five-year bill is between $29,607 and $31,775.
Environmentally? Diesel has come a long way, but the Jetta still only scores an EPA rating of 6/10 for smog. You'll get through 56 barrels of oil in five years, and puff out 25 tons of CO2, with a further 6.5 tons of upstream greenhouse gases.
