Hello and welcome to EcoModder
The Fiesta is a very economical car to start with, but I'm sure you can do even better.
Other than pumping up your tires and adjusting your driving style (which I'm sure you have already done), here are a few ideas:
- Grille block, at least partial, but a full block with closeable holes is better,
- Fold or remove the passenger side mirror,
- Narrower and/or taller tires with low rolling resistance,
- Alternator cut off switch with a larger battery,
- Engine kill button,
- Bellypan (under the engine, and maybe all the way back),
- Flat wheel covers (hubcaps),
- Rear wheel skirts,
- Kammback.
The above mods should let you easily get below 4 l/100km. Check out
65+ Efficiency Mods for more ideas.
The '92 Fiesta has a very nicely shaped rear hatch for adding a Kammie, it could be at least 60-70cm long. I'd love to see how much of an improvement it would give.
