[MetroMPG], an environmentally friendly car enthusiast from Ontario, added a tail to his car to increase gas mileage. This 1998 Pontiac Firefly is a sibling of the cheap and popular Geo Metro. He had already done some work to cover a portion of the rear wheel wells to reduce drag. Using cardboard, duct tape, and an aluminum frame he extended the rear of the car by around six feet.
The results are pretty impressive. His extensive testing can be seen in the video after the break and reveals a Miles Per Gallon increase of 15.1% at 90 km/h to get to 64 MPG. The tail is removable but we’re thinking it’s a pain to keep relocating the tail lights from the original body to the removable one.
Now we’re wondering if someone is doing this to our Smurf-blue Metro that we sold to the junk man for $100 back in 2001. It ran great, if you weren’t caught in the cloud of blue smoke coming out the back.

[Doug Heffron] modified this 1989 Geo Metro way back in 1993. Gas prices had just started breaking $1.00/gallon and he wanted to show manufacturers how to build a fuel efficient vehicle in such troubling times. The car already got 58mpg (Prius: 46mpg), but [Doug] decided he could do better with some aero modifications. The car was converted to tandem seating and stripped of any extra weight. In its final form, it got 75mpg, but then gas prices stabilized and it was laid to rest in a shed. You can find out more about the car and see photos from the build on its site (painful resizing).
[dcb] posted about his work on the
mpgduino mpguino. The project uses an arduino with a LCD display to monitor fuel consumption based on vehicle speed and the pulses of the fuel injectors being fired. It’s definitely an interesting project given current fuel costs and the passive nature of the project. You can easily tap the wires needed for the monitor and remove it without voiding your warranty (not that we really care).
