thus the celerio is the most fuel efficient?

how about the new 2012 picanto?

Hard to say, as those figures were all taken at different times in different conditions. In fact, the Honda Jazz and Honda City in those runs are likely the previous generation GD-chassis CVT ones, not the current 5AT models.

The Celerio is fuel efficent but the numbers are DOE's idea of real world fuel economy figures which are unachievable in normal driving conditions unless you normally drive along the expressways with traffic sweepers ahead of you.

how about this one?

[SIZE=3]Basta diesel engines and whether it be 2.5-litre or 3.0-litre, simula't-sapol, maaasahan talaga ang mga Isuzu's.... Pinaka-matitipid at pinaka-matitibay na makina [/SIZE]

Isuzu D-Max 4×2 pickup (manual 2.5L diesel) — 20.57 km/L; you spend just P2.24 per km

Isuzu Alterra 4×2 full-size SUV (manual 3.0L diesel) — 19.44 km/L; you spend just P2.37 per km

It is a factor of speed increases friction and resistance and requires more energy to overcome. Driving slowly is slightly less fuel efficient than driving at a constant speed of 55 or 60, but at a slow speed the wind friction is reduced and the fuel economy is less affected. It also matters if you are driving into the wind or if the wind is behind you and 'pushing' the vehicle.

Does this mean that during traffic your fuel efficiency is affected because you tend to drive slowly and erratically?

Maintaining a steady speed, the engine uses very little power, and thus, very little fuel.

Under acceleration, the engine will use more power, and thus more fuel. Maybe five to ten times the fuel you use while cruising. Fuel which is wasted, because you will have to brake to a stop, afterwards.

This is not to mention the use of AC in traffic, which means that you're burning one to two liters of gas per hour while idling at the stoplights.

To save more fuel in the city, avoid idling at all costs. And try to never use your brakes.

To clarify, if you accelerate hard enough to need to use your brakes to stop at the next stoplight or traffic snarl, you're wasting gas. If you only accelerate enough so that you can coast almost to a stop at the next light, you're using as little gas as possible. This is known as pulse and glide.

Smart city driving avoids traffic lights, or avoids waiting at traffic lights. These new LED lights with timers are a big help. If you know you're not going to make the next green, you can slow down and coast, to minimize the time you'll spend waiting at the red light. You can also shut the engine down if you see that you will be waiting more than thirty seconds for the next green.

More extreme hypermilers will pulse and glide, even on the highway. The most extreme ones will turn off the engine and glide in neutral. This makes for some absolutely amazing mileage, but without the proper equipment (engine kill switch... manual transmission for bump-starting in gear), it's highly dangerous.
