The AX Eco Project : 100 mpg target ! In the 90's, the super light Citroën AX diesel held a Guinness record as the most efficient production car available, capable of 65 mpg (US) at 56 mph (90 km/h). HypermilerAX's modifications have already improved this to 80 mpg (US) at 56 mph. Now he's aiming for 90 mpg to beat the 1994 "AX Eco" concept car, and is also eyeing a 100 mpg tank (2000 km).

Taller Tire Test (5.7% MPG increase observed on Honda CR-Z @ 55-65 MPH) The purpose of the test was to determine whether larger diameter tires, which result in lower engine RPM and higher load for a given speed, can improve gas mileage. The test car has a 6-speed manual transmission. At highway speeds (55-65 MPH), the larger tires gave a 5.7% average increase in MPG. The engine ran about 200 RPM lower. By SecondWind - 72 replies
