I have to agree. Especially the part about changing gears to 5th -- The correct answer quoted is 45-50 mph (i.e., 72-80 kmph) for optimal fuel economy. I suspect the correct answer under Inidan city conditions is 25-30 mph, which is what I selected. I think 45-50 mph may be fine for the highway, but not for city and probably not for under-powered Indian cars -- may be true for the high-powered vehicles that you see in UK or US.

Similarly, the claim that "For the average family car the most economical speed to drive is 50-60 mph" will probably not hold in Indian city conditions. 80-100 kmph? Maybe true on the Mumbai-Pune Expressway, not elsewhere, and again not for under-powered Indian cars (like my Santro). I would say that under city conditions, 50-60 kmph is the most economical speed to drive cars like my Santro.

The other answer that took me by surprise is the claim that mileage drops only by 2% if you under-inflate tyres by 20%. Again, that would depend very much on the driving conditions. I suspect that under Indian city conditions you will pay a much higher price for such severe under-inflation; the claim may be true for moderate speeds on the highway. The Carbibles website quotes a guy claiming that he got a 25% improvement in fuel economy with 25-35% increase in tyre pressures (from 32(f)-28(r) to 40 psi for all tyres).

About the optimal rpm for gear shifts -- I had no idea, since my car doesn't have a tacho. I guessed 1000-1500 rpm, the answer was 1500-2500 rpm. Wonder if this too will hold up for small Indian cars in Indian city conditions (where fuel economy matters most for a pollution-free environment).

Needless to say, I flunked this test (3/8).

From my Santro manual:

Quote:
------------------------Recommended km/h
Gear shifts---------Better acc. ----------Better FE
1-2 or 2-1-------------20------------------10
2-3 or 3-2-------------40------------------30
3-4 or 4-3-------------50------------------40
4-5 or 5-4-------------60------------------50
I suspect that the "Better FE" speeds will correspond to 1000-1500 rpm (or at least close to 1500 rpm). Also the fifth gear shift speed for better FE corresponds to ~30 mph rather than the 45-50 mph recommended by the test website (which I suspect holds for bigger cars on relatively traffic-free roads).

Scored 4/8

Hmm not bad, like our Opposition Leader, you can talk the talk, but how much of it is just to impress? You definitely could do better

scored 6/8, only 1 attempt.

Get you, eco-driver. In fact, we'd be surprised if you own a car at all, no doubt you've already traded it in for a bicycle and given the profits to a tree-planting outfit.

However i follow the below points to save the resource and say green drive.
1. Pick up my friend who is going in bus or bike to office.(if possible)
2. Switch off the engine in signal or heavy traffic.
3. Switch off the light also. I believe the light too contribute some amount of heat to outside.
4. Use the AC only when required very badly,
5. Use my bike rather car for every day travel to office and near by. (less time and fuel)
6. Stop my car 2 feet back rather stopping my car in mid of the signal and allow other vehicle smoothly. This way we all save time and fuel
7. Most imp:- I dont acc high un-necessary.
8. If I see red signal from enough distance, i remove the leg from acc. Slow down from early rather breaking hard and the end.

....

Least but not the last planning for huge Tree Plantation this monsoon. So we need less AC. What do u say ?
