It's an efficient car, and it can do really well if you let it. If you actively try to drive it more efficiently, there's a lot of room for you to work with. If you modify it (SiRca90 even played with the gearing) and work it hard, then you can get even better results.

YMMV, as it were.

 

I agree with if you work at it you can get very good MPG. Myself I drive and accelerate very gently so I get real good mileage. However, some of the mileage claims here are embellished.

The Fit is a great little car but MPG wise it's outdone buy other cars in it's class.

 

It is. But it beats the hell out of them on interior space! Everything's a compromise.
