I would like to see one additional option when picking engine type. It would be nice to have an L4 Turbo option.
I have a Kia Optima. The Optima can have the standard L4, L4 turbo, or L4 hybrid. However, there is no turbo option to pick from. So, they get lumped with all the L4 Sedans. It would be nice to track the turbo gas mileage separately, just like the Hybrid's are tracked separately.
We know that the level of detail we track here at Fuelly is not going to work for everyone, but we also feel like we have a good balance as things stand now.
People are free to include more detail about their vehicle in their title or description. That will help people who want to do more digging to know why a particular vehicle might be getting better or worse fuel economy than others.
