I don't think it's quite the same. Especially since you say that you can only achieve 100 mpg for a short period of time.
The reality is that their system does not do anything to increase the mpg. Once the stored electrical energy from being plugged in has been used up I'm sure the mileage is actually worse due to all the added weight.
I think the idea is alright - just horribly misrepresented.
As far as buying less gas at the pump - sure you are getting more miles per gallon of gas purchased but the numbers are meaningless. Owners of electric vehicles never buy gas at the pump, they get infinte mpg. If I added batteries and an electric motor to my minivan I could also get infinite mpg - as long as my trips were short enough not to drain my storage batteries. If my trips were just a little longer my mileage might go down to 1000 mpg. The longer my trip the less my mpg. It does not represent how efficiently the vehicle converts gasoline to useful work.
