Dam, It works! (Air dam on Smart Fortwo: 3-4% MPG improvement)   Dam, It works! (Air dam on Smart Fortwo: 3-4% MPG improvement)
In addition to a clear lower grille block and smooth, black wheel covers, Chumly added and tested a simple air dam: "I just made an air dam out of some lawn edging. A-B-A testing shows 3.16% - 4.2% (avg 3.73%) better mileage. It took a whole half hour to make and install it, I should have done this a long time ago!"

They're out there, people. (Our non-North American members should feel free to laugh at our concept of 'efficient' little cars.)

1997 Civic CX to HX engine/VX trans swap! 63 MPG @ 62 MPH   1997 Civic CX to HX engine/VX trans swap! 63 MPG @ 62 MPH
When his 1997 Civic CX engine needed a lot of work, turbovr41991 decided to spend his repair time doing something different: he picked up a rusty Civic HX and swapped over the more efficient lean burn engine instead, and went with the more efficient gearing of the Civic VX. With a few other modifications in place, the car is returning seriously impressive highway fuel economy.
