Ano po ba talaga ang ibig sabihin pag sinabi nating "city/mixed/highway driving"?

[valacirca]

...but in the real world, i do only 10 kph."

lol. sounds like my daily drive to and from work.

[valacirca]

Lahat naman, kahit light/moderate/heavy traffic, subjective eh.

Which is why it would be better if there were standards in place. The best I think would be average speed. Pero once ma-settle kung anong average speed yung light/moderate/heavy traffic... ang next issue ay kung anong klaseng travel naman yun: 20kph nga, pero ano yung 20kph na yun... constant 20kph? o halo nang mabilis at mabagal na stretches? Because the latter would be less fuel efficient than the former.

Mas madali pa nga intindihin yung highway/city coz 2 ideas lang siya.

I beg to differ. Kung mahirap intindihin yung light/moderate/heavy traffic dahil subjective siya, mas mahirap pa lalong intindihin yung pinaghalu-halo mo lahat ng subjectivity na yun sa isang generalization na tinatawag na "city driving."

Can't tell the average speed if you don't have a MID in your car that tells you your average speed during one of your trips. You can't also assume what your speed was because you don't look at your speedometer over & over again.

Mas madali siguro kung combined yun ideas. For example, city driving but with very heavy traffic (insert details here) or city driving but with light traffic (insert details here)

Kasi yun nga, you can't just have three conditions -- light, moderate, heavy. Kasi kahit gaano ka-light yung traffic around the Metropolis, iba pa rin results niya from what you'll get on a steady pace * the highway.

Isn't it better to classify fuel consumption/economy readings based heavy/moderate/light traffic?

Iki-clasify naman yan ng mga Tsikoter lalo na yung mga skeptic, yung mga mas nakakaintindi, at mas gusto ang detail presentation.

Yung iba naman simple lang ang details, so assume mo na normal driving habit.

Meron din namang binibigay na standard ang mga manufacturer, critics, reviews... Good to start din yun for initial refference.

Finally, it's up to you kung ano mga standard ang gusto mong gamitin!

[steer]

kung ganun gagawin then hindi na ganon ka dependent sa traffic and weather conditions.

po! but, how many of us drive to the office daily, with our car running at a constant 20 ( or 60 or 100 kph) on an open race track?
i mean, such testing would and couldn't translate to real or practical driving experience, which is what we all do..

envision the ff: "my car gives me 20 km/li when i run it at a constant 60 kph on an open, no-traffic race track. but in the real world, i do only 10 kpl."
so, do i compute my monthly fuel budget based on the track performance, or on real-life, everyday performance?[/QUOTE]



my suggestion was based on the fact that the environment should be the same when testing vehicles, hence testing it on a open track.


of course, the ideal test would be on real traffic, but how can you test several cars on a constant environment, when the traffic is variable.

If you test vehicle A now and record fuel consumption, by the time you test vehicle B, live traffic would have been different when vehicle A was tested.

ang bottom line lang dito ay katangap tangap ba na ang FC mo na napakataas compared sa FC (similar car) na-post ng ka-tsikoter.

pero ang natutuhan ko lang, did you enjoy your drive or did you wish nag commute ka na lang

Siguro mas clear kung ganito ang post:

Ang FC ng RAV4 4x4 AT Gen2 ko ay 6.5km/l (average)
Mon-Friday Las Pinas-Sucat-Villamor-Skyway-Makati (and back) 1-1.5hr drive pag umaga pero sa gabi 2hrs min.
Sat-Sun long drive (bulacan, cavite or tagaytay)

[Retz]

average speed in city driving is only 10-40km/hr. sa macapagal lang ako humahataw pero 60km/hr lang.

One thing to add to the equation: driver mood.

We are proposing for the PCOTY a fuel economy test on the racetrack with a target lap time, sections where you have to hold 60 kmh, sections where you hold 30 kmh, and sections where you stop.

In testing, economy indicated is equal to light traffic, but it is very difficult to do.

Very hard to simulate traffic. Taking slightly longer to stop or start in one car will build up over several laps.

The best way is to do a dyno test instead of an on-road test. This allows you to vary and spedify load, and to control weather conditions.

For me, since I have an MID, I base it on average speed.

This takes care of the issue on whether or not it is city/highway/mixed driving.

It does not however consider uphill or downhill routes.
