    Optimum speed (maximize mpg) for corolla?

    Hi,

    The EPA has a generic graph for optimum speed (to maximize mpg) here (http://www.fueleconomy.gov/feg/driveHabits.shtml).

    Does any one know of an official publication (EPA or Toyota) that lists this curve for a corolla 2002, and suggests a specific optimum speed given this model?

    thanks!

    As far as I know - there is no official study done on the 8th gen Corollas. I wouldn't consider the EPA testing for city/highway MPG numbers for the 8th gen Corolla an
    realistic study - as they operate the vehicle in conditions that are unrealistic to begin with.

    Usually in the testing of the sample vehicle - one test driver, no extra equipment, no additional accessory usage, temperature controlled test. Specific acceleration, deceleration, and idling according to a preset test matrix (average "city" speed about 20 MPH and average "highway" speed 48 MPH).

    Usually the city numbers are from a 11-mile course to be completed within 31 minutes, has 23 stops, and around 18% of the total time spent just idling.

    Usually the "highway" portion is a 10-mile course, no stops and max speed of 60MPH).

    Also, they don't even use pump gas - they use a special laboratory fuel called indolene
    (2,3-dihydro-1H-indole).

    Best source would be forums such as these - I've heard reports that some can hit mid to high 40s in the CITY (9th gen Corolla, 5-speed, OEM tires). Most of the 8th and 7th gen people have seen max MPG at 50-55 MPH - still only around the 40 MPG mark or lower. The optimum MPG for your particular car would be different from others - it would be nice if you could set your cruise control to some XX MPH and get max fuel economy - but it is sometimes not that simple. Speed is only one aspect or many that you have to be aware of that could impact your overall fuel economy.

    on my 02 I'd imagine the best mileage is as slow as I can go in 5th, which is 45mph

    I bet you could exceed 40mpg if you held that speed long enough

    I got about 35-38 in the city and usually around 40-42 once I get to speed on the highway(75-80mph).
