Fuel Economical Car of 2011
One of the main reason that makes downside to economic recovery (which nobody would complain about right now) is higher costs of fuel.
The most fuel efficient vehicles were pricey due to their new technology and scarcity.
The annual fuel costs listed are based on 45% highway, 55% city driving, 15,000 annual miles and a fuel price of $ 3.09 per gallon.
Each vehicle has two fuel economy estimates:
A city estimate that represents urban driving, in which a vehicle is started inthe morning (after being parked all night) and driven in stop-and-go traffic
A highway estimate that represents a mixture of rural and interstate highway driving in a warmed-up vehicle, typical of longer trips in free-flowing traffic.
Fuel economy is not a fixed number; it varies significantly based on where you drive, how you drive, and other factors.
Thus, it is impossible for one set of estimates to predict fuel economy precisely for all drivers in all environments.
