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

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. :grin:

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.

Para kay ermats ang "trafik" may tumawid na kalabaw sa kalsada :grin: 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.

Doesn't take into account the TS' main issue: traffic. The stop-and-go is the mileage killer.

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?

Kapag sinabi kasing city, usually incorporated na dun sa idea na yun ang stop and go traffic/situation. Kapag highway naman, long trips at a constant speed. With minimal stop & go situations.

Kapag mixed, tipong nag-highway ka tapos naipit ka rin sa traffic ng matagal.

Lahat naman, kahit light/moderate/heavy traffic, subjective eh. Mas madali pa nga intindihin yung highway/city coz 2 ideas lang siya.

Yun light kasi, pwedeng travel around the city w/ no traffic. For example, around BGC ng madaling araw. :) Iba pa rin yun than driving * the highway na diretso w/ no traffic din. Di ka naman pwede magmaintain ng 60kph+ speed around BGC
