The Elio has an 8 gallon gas tank with a range over 650 miles, no car I've ever owned had or needed that kind of range. Why not reduce the tank to 4-5 gallons and use that saved space for additional storage?
Absolutely not!
Perhaps you don't live in the desert, like I do, where it can be a good distance between gas stations. I am very tired of having to constantly go to the gas station so often.
The gas tank is under the rear seat. The only more space provided would be for people with big butts. It is a space that can not be used for "storage".
Recently they lowered the seat for taller people and made the tank smaller. I wish they had left the tank and seat the way they were.
I find nothing enjoyable about going to the gas station. A vehicle designed so gas station visits are minimized, is a good design.
