    Default what is the best speed to get maximum fuel average in 1300cc manual city?

    My question is regarding the fuel average of honda city 2016.
    I am totally confused about the its economy speed. Some people claims that the city's economy speed is 80-90 Km/hr but some people Claims that its economy speed is 100-110 km/hr.
    Can anyone tell me its accurate economy speed at which i get maximum mileage in one tank of petrol? THe answer should be on the practical point of view.
    Thanks

    There is a simple test you can do to find it.

    1- First, drive around a bit until the engine is completely warmed up. Completely warmed up means that the fan should kick in and shut down twice; this usually takes 8-10 km.

    2 - Find a long, fairly level road with almost no traffic. It should be somewhere where you can safely maintain 90+ km/h. Maybe GT Road before sunrise?

    3- Accelerate normally to 50 km/h, upshift 5th gear, and reset your on-board mileage meter. Maintain this speed (in 5th gear) for at least 1.5 - 2.0 km, and note your mileage.

    4- Increase your speed by 10 km/h, and repeat step 3. Do this until you hit the legal speed limit of the road, or whatever you speed you feel is safe.

    You will know which speed is the most fuel efficient. I am willing to bet that you will get the best fuel economy between 60-70 km/h. It will keep decreasing slightly until 90-100 km/h, and above that it will drop off sharply. Do a little experimentation, and see what you are comfortable at.

    Keeping an engine at around its peak torque rpm is efficient. What rpm does the engine develop its peak torque, and what would be the speed at that rpm in top gear? That would be close to the most efficient speed, barring any unusually tall overdrive ratios.

    I usually drive below 2.5k rpm. Plus run time average is available all the time. You can adopt the style that keeps its above 10kmpl

    That applies only to Wide Open Throttle situations; at part throttle, the RPM should be kept well below peak torque RPM.

    Max twist in the Honda City occurs at 4.3k RPM; manual transmission versions will be somewhere north of 135 km/h at that speed.

    But below 2.5K rpm means that you are running around 70-80 km/hr in 5th gear right?

    Of course. That is why I used the word "efficient" instead of fuel economy. The journey will go by much quicker at the higher speed, preserving the only truly non-renewable resource - time.

    To be efficient timewise, peak torque doesn't even come into play; your best bet would be to redline each gear, and zip through lanes as though your life depended on it

    On a more serious note, there isn't too much time difference between driving 70-75 mph on the interstate, and driving 55-60 on a secondary highway. The latter is much safer, and will get you to your destination much more relaxed. It's also better for the environment; it also saves precious forex, so its more patriotic.

    True, dat!

    To get back to the original question, the style of driving probably has more to do with the overall economy than the precise speed. Having said that, keeping the car in top gear without lugging the engine would work well in saving fuel.

    The practical response is pretty simple, observe the eco meter which shows instantaneous mileage, each time you see it dropping, release throttle and press it slightly, this method would help you attain maximum economy at any speed. As for highway usage, keep it between 80-90 and you shall get great mileage

    There is something interesting that I established over the weekend that may be of interest to the OP here. My LX470, with the aerodynamics of a shiny barndoor, gets 14.3 mpg at 70 mph, and gets 14.8 mpg at 80 mph. Engine efficiency near the torque peak matters too.
