Home made Boat Tail Car Retrofit Gives Geo Metro Amazing Fuel Economy
A homemade boat tail added onto the end of a 1998 Pontiac Firefly (or the Geo Metro) has boosted the car's fuel economy to 64 mpg, or 15.1 percent at 90 km/hr (56 mph). Cosgrove, the owner of this car, used cardboard, aluminum and duct tape to extend the back end of his 1998 Pontiac Firefly by 4.5 feet. The modification took him about 14 hours to do, and the results are impressive enough that he’s planning a sturdier version made of more durable materials. Another impressive car retrofit that boasts 95 mpg: Mike Turner’s Aerocivic, a Honda Civic with a somewhat similar tail design. So are these boat tails going to be the future in fuel efficient automobile design?
