If you could get the dealer (not likely) or a friend to let you drive one on the same route, you might find out more about what economy you can expect. You must let the car cool down before starting your trip in order to know what the mileage will be, as the first few minutes warming up are the worst. Unless it's very cold, you should be on electric operation in about 7-10 minutes or three to four miles. If you immediately get on the freeway, you won't get much benefit unless it's stop-and-go traffic and then you'll get a lot of benefit!

Don't put too much faith in numbers from dealer test drives. The car usually doesn't warm up enough, the engine is too new, and you haven't learned how to drive the vehicle for best mileage.

But overall, if you only drive a short distance for work, you might use a lot more fuel for recreation and other things. That is where the FEH will shine.
