Fuel economy tags on new private vehicles for sale

[Bitulo]

Mga Katsikots:
Because of the high cost of fuels like gasoline and diesel and the need to economize, IMHO, it is about time that our government will impose a requirement that all new private vehicles for sale should bear a tag or sticker indicating their certified kilometer per liter consumption or fuel economy (FE) both for city and highway driving. This will give buyers like you and me additional information that should guide us in deciding which units to buy.

This is similar to the US EPA stickers required to be posted on all new vehicles in the US for sale. This will give us an idea how the vehicles compare with each other on fuel consumption based on standardized and comparable criteria. As it is, every car company claims its own FE determined based on their own method of testing. Some even go to the extent of sponsoring caravans or actual road driving test, which in the end is meaningless because of the uncontrolled test variables. This situation just contributes to the confusion of everybody except the confusers – hehehe!!!

Ano sa tingin niyo? Siguro kalampagin natin para gumalaw dito ang DTI, LTO at DOE.

First thing first... who's fuel economy figures would you want posted on the car? From the DTI? From the car maker? from the DOE? from the US EPA?

+1 paps.

seriously i don't care where they get the figures as long as the reference is standard across all manufacturers and dealers.

This would require the DOE to buy a dynamometer and a rig for testing fuel economy, and to develop standards.

Our problem is we have vehicles built in Japan/Korea that are not sold in the US, vehicles from the US that are not sold in Japan, and vehicles from the ASEAN that not sold anywhere else.

So we have cars that only have Japan 10/15 ratings, cars that only have US EPA ratings, and cars that have not been officially rated by anybody, or which only carry the Indian economy ratings. These ratings are all based on completely different standards.

To rate these cars, the DOE will have to set up a testing center and will need to train drivers to perform economy tests set to very strict standards. Then you'd have to come up with a way to calculate economy loss due to wind resistance. In other words... we need a small wind tunnel or a place to do coast-down testing.

That'd be a full-time job, as there are sixty or so new cars and variants that come out every year in the Philippines, and over two hundred distinct variants of all cars on the road today.

Give me a dynamometer (has to be rolling road, can't be the Dynapack Speedlab uses), an operator and a clean room with a controlled environment, and I could probably test four cars a week, and have the official results by June of next year. But I'd need an operational budget in the millions to get it done. Just constructing the testing facility alone would probably require twenty or thirty million bucks.

It will open the dealers up to lawsuits. Lawsuits cost money.

Those lawsuits are frivolous. EPA mileage is understood to be a reference point only, and not a promise. As the saying goes, YMMV. The only one with merit is the Honda Hybrid one, because the fuel economy DID change after the reflash, and the official EPA ratings changed to reflect this.

That won't work.

Real-life economy is never exactly the same from person to person. You have people driving in different traffic situations, with different quality fuels, non-standard tire pressures and with different driving styles.

Even driving the same cars on the same route with the same starting and ending time, as we do in eco-runs, the spread can be 5-10 km/l.

Tessa Salazar's run through Divisoria-level traffic with superminis got her 6 km/l.

I drive the same cars in regular urban traffic and got 10-15 km/l.

Fuel economy can only be measured comparably in controlled conditions. Ergo: Climate controlled dyno, with wind resistance and weight factored into the calculations. The US EPA test is annoyingly precise about this, but we'd have to develop our own regimen, and we'd need help from mathematicians and physicists to develop conversion factors for the resistance used on the dyno, otherwise our numbers would be useless.

Me, I'd measure spot fuel consumption at 40 km/h, 60 km/h and 80 km/h. Then measure fuel consumption during acceleration separately. Then measure spot consumption at idle with the AC running full blast.

Put all of these figures in a graph, for easy reference. Much more useful than the US two-number system.

source lang ng corruption yan..

hindi kasi focus ang pinoy sa objective ng mga programs..

tingnan nyo lang yung DTI sticker requirement sa mga helmet?? kalokohan yung bibili ka ng sticker ng DTI without the DTI really certifying the product thru proper testing.. so kahit peke helmet mo basta may DTI sticker ok na.. so ano pa silbi nun

same lang sa tagging na yan...

Isn't DTI certification merely to show that the product is safe to use and contains no harmful chemicals? It's not a crash-standards certification.

diba si Mr. Nuvi-Nuvi nagpapatesting sa UP?

can the govt use that as the testing facility?
