* Based on 45% highway driving, 55% city driving, 15000 annual miles and the price
of fuel used by the vehicle. You may personalize these values to reflect the price
of fuel in your area and your own driving patterns.
Compressed Natural Gas (CNG) is normally dispensed in "equivalent gallons" where
one "equivalent gallon" is equals to 121.5 cubic feet of CNG. The fuel economy for
natural gas vehicles is shown in miles per gallon-equivalent.
The carbon footprint measures greenhouse gas emissions expressed in CO2 equivalents.
The estimates presented here are "full fuel-cycle estimates" and include the three
major greenhouse gases emitted by motor vehicles: carbon dioxide, nitrous oxide,
and methane. Full fuel-cycle estimates consider all steps in the use of a fuel, from
production and refining to distribution and final use. Vehicle manufacture is excluded.

Save Energy & CO2 - Drive one of these cars instead of taking transit
The average transit bus gets 29.52 passenger-miles per gallon.
If you want to save energy, just get a car that gets better mileage!
The table lists miles per gallon for the whole vehicle. To correct for the fact that
the average vehicle in the USA carries 1.57 people, adjust that bus passenger mileage
of 29.52 to a car equivalent by dividing by 1.57. This yields 18.8 vehicle miles
per gallon for a car with an average of 1.57 people to match an average transit bus.
Just scan down the table till you hit a city mileage of 18.8 mpg and all cars above
that point beat taking the bus for energy consumption.
For light rail, the number is 28.6 mpg
For Amtrak, the number is 30.0 mpg (use highway mileage here as we are now comparing
inter city transportation.
This car and all those above it beat the average transit bus on energy consumption
This car and all those above it beat the average Amtrak train on energy consumption
This car and all those above it beat the average light rail train on energy consumption
