Busting the 40-MPG Myth: Only Hybrids Really Reach 40
In recent months, a handful of small gas cars like the Chevy Cruze Eco, Ford Fiesta, and Hyundai Elantra have hit the market as affordable alternatives for drivers seeking hybrid-like fuel economy without the hybrid price premium. Advertisements from Ford, Chevy, and Hyundai have proudly attached the “40 MPG” badge-of-honor to these models in campaigns that are often geared especially to reach a younger, more urban driving demographic. In truth though, there are currently absolutely zero gasoline-only vehicles available in the United States offering EPA-rated combined fuel economy reaching 40 mpg.
So are the carmakers lying? Not really, but the discrepancy between the numbers seen in the ads and the real-world efficiency of those small gas-powered cars reveals that some auto companies are only telling a half-truth.
If you look closely, the 40-mpg claims made in commercials for cars like the Cruze Eco and Ford Fiesta, refer only to highway driving—which is far less taxing on gas cars than the city. The full truth is that the Chevy Cruze Eco for instance, gets 42 mpg on the highway but just 28 mpg in the city, for a combined rating of 33 mpg.
For a number of reasons—such as the use of electric power for low-speed driving and the use of regenerative braking to recapture energy lost while coming to a stop—most hybrids achieve better efficiency in the city than they do on the open road. The Toyota Prius for example, gets a 51 mpg / 48 mpg split, for a combined rating of 50 mpg. Another example: The Honda Civic Hybrid, without waving a banner of some kind of breakthrough, gets 43 mpg on the highway, and 40 in the city.
With more than 80 percent of the U.S. population residing in cities or suburbs, most drivers find that the real-world efficiency of their car more closely resembles its city and/or its combined ratings than its highway number. And as gas prices rise, that difference is becoming significantly more valuable.
Honda CR-Z Delivers MPG and a Dose of Fun
By Larry E. Hall
Last year, HybridCars.com staffers drove a CVT-equipped Honda CR-Z on a 125-mile loop to see how the sporty hybrid coupe fared. The drive consisted of a broad sampling of road conditions: highways, town streets, and sweeping country roads. At the end of the run the coupe tallied 35.3 miles per gallon—three tenths more mpg than the EPA city rating of 35 mpg in the city, and nearly 4 mpg shy of the 39 highway rating. The conclusion: maybe a little too raucous during in-town driving, but overall what most drivers will experience.
A few weeks ago, I checked out a manual shift CR-Z EX with navigation for a week. Logging 379 miles during the seven days, fuel mileage was recorded in three segments: 73 miles of normal running errands and shopping in town; 132 mile drive from Olympia, Wash. to Seattle during morning and late afternoon brake lights and gridlocks; and 174 miles of hey, let’s flog this thing and see just how sporty it is, and oh yeah, how much gas did the little four-banger guzzle.
No one has ever accused me of having a light foot on the go pedal, although I have changed my driving habits the past several years. I just didn’t know how much until I looked at the mpg numbers of the CR-Z that said, “Oh no, you’re becoming a greenie!”
Great MPG, With Some Work
During my drives about town the colored ring around the speedometer was primarily green, but I didn’t need it as a reminder that mode selection was Econ. The word slug best defines the forward motion of the CR-Z in this setting, and following the shift-up and shift-down indicator arrows was foreign even to my changed driving habits. Really Honda, upshift from 1st to 2nd at 15 mph, and from 2nd to 3rd at 18 mph? But, it works; fuel economy averaged 43.3 mpg—12.3 more than the government’s 31 mpg. Makes one wonder how those EPA folks come up with their numbers. Oh please, don’t tell me I have succumbed to hypermiling.
