When it comes to ranking fuel efficient cars, Consumer Reports doesn’t rely on EPA numbers. It conducts its own real world tests. CR says:
“Measuring fuel economy is among our more than 50 tests we conduct on each car we purchase. Our fuel economy numbers are derived from a precision flow meter and are rounded to the nearest mile per gallon (mpg). CR’s overall mileage is calculated from equal portions of city and highway driving.”
The BMW i3 Giga tops the current list of 20 most fuel efficient cars with an overall average of 139 MPGe. Check out this list for the rest of CR’s top 20.
* = MPGe ** = MPG on gas only
