    Parang mahirap lang kasing intindihin yung ibang fuel consumption stats pag sinabi lang halimbawa na "taken while city driving."

    Kasi may ibang parts ng city na mabilis at maluwag ang traffic. May iba namang parts ng city na mabagal at masikip ang traffic. Nagbabago din ang traffic conditions sa city based on time of day and weather (kung umuulan o hindi). So hindi naman consistent ang traffic conditions ng "city driving" diba?

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

    mdyo subjective nga talaga yan kasi hindi naman lahat ng city ay ma traffic. but majority pag sinabing city driving inclusive na ang traffic.

    hindi din naman pareho pareho yung pagsukat sa heavy/moderate/light traffic.. dapat yung km travelled and how long did it took you.. like 20 kms distance took you 1.5 hours.. so that's only around 14kms per hour for 1.5 hours..

    On top of that iba iba din ang weather conditions and driving style. So kahit sabihin mong same heavy traffic pero kung ang drivers ay si hypermiler vs Mr Freeze may diff pa din.

    Eh, unrealistic ang assumptions ng mga iba. Sasabihin nila... bakit yung "H" o "K" o "F", 7 km/l lang sa traffic, yung "T" kaya mag 11 km/l.

    Pero in reality, 11 km/l yun, Sunday morning. Kung heavy traffic din, mga 7 km/l din.

    I've driven them all. And while mga iba, yes, medyo malakas sa gas... hindi naman night and day difference. Minsan, 0.5 km/l to 1 km/l lang difference sa isa't isa.

    Ang pagbalik ng comeback...

    Para kay ermats ang "trafik" may tumawid na kalabaw sa kalsada Kaya di nya maintindihan bakit di ako makarating ng airport from San Juan in 15 mins eh ang lapit lang daw nun :hysterical:

    dapat siguro magkaroon nalang ng standard testing sa isang open race track.


    for example at one hour interval each:


    car running at 20 kph gets XX kilometers per liter.

    car running at 60 kph gets XX kilometers per liter.

    car running at 100 kph gets XX kilometers per liter.

    car running at 180 kph gets XX kilometers per liter.


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

    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!

    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.

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