Kaka gulat ang D-Max. Mirage 1.2L MT mas malakas uminom ng gasolina kesa 1.6L MT Elantra??

The Elantra 1.6L engine is very good. At 80kph it was probably just snoring hehehe

[niky]

The D-Max is likely a fluke. 20+ is indeed possible with the 3.0... have done it on the Alterra... but 38 sounds like a filling error.

-

Some of the variability can be down to unit condition, tires and even driver differences.

Civic and Elantra, remains to be seen, but if you have the right gearing, I think 20+ can be done in these two. Not sure about 27...

[GTi]

23 on the MUX A/T is already impressive. But 38 when the Accent CRDi didn't even reach 30?

I think its not a fluke. Isuzu is king lol. Galing talaga tong mga eco run.

Brio 1.3ats cant beat its 1.5L jazz/mobilio siblings. Interesting.

HondaPH should bring in the brio 1.2 with cvts those can compete with the celerios.

I wish toyota brought the new vios to this eco run. It would have obliterated the competition

[Lew_Alcindor]

as i understood it, the test was designed to compare relative fuel efficiencies of the various cars, driven under the the exactsame conditions.

I get your point. But I think giving the consumers a realistic figure is better.

I mean in this test run a vehicle will register 20km/L when in real life driving it is probably half of that.

That's what happens when you let manufacturers select their own drivers. All the sneaky tricks you can get away with during the filling and run really do work.

Heck, I think a substitute for rocking while filling could be to fill up the car as far beyond the full mark as possible before the "official" fill, hit a whole lot of bumps and ruts to shake up the fuel in the tank on the way to the filling station, and take your initial hit of gas.

-

In this case, the DOE should INSIST that all cars come to the official filling point with tanks with half a load of fuel or less.


RE: Brio, not surprised. The CVT on the Jazz/City is fantastic, allowing ultra-low cruising rpm.


RE: The Vios... hehehehehe.

I agree. I think it would have been better if they have taken actual videos during their test.

Did they seal the fuel door? I didnt see it in the articles. Some eco runs have the fuel doors sealed so that only the organizers can fill the fuel.

Bro do you honestly believe that a slightly lighter body (with poorer aerodynamics) and a manual transmission would improve fuel consumption by almost 100%?

300 km * 38 km/L means they only filled up 7.89L. Like I said, fillups this small are very, very prone to error. Most likely their tank was initially filled above the automatic cutoff, or their second full tank did not reach (or prematurely, erroneously reached) the automatic cutoff, or both.

I did 27 km/L with my Vios 1.3 once, but when I reran the test on a longer route it was only 21.26 km/L.

Full to Full*– To make the most out of the trip, all 70 vehicles had their fuel tanks filled up to the neck. The fuel cap was then placed with a safety seal to make sure the fuel level was not tampered with. Other sections of the car like the hood and trunk also had safety seals, ensuring that the engine, fuel tank and load capacity cannot be fiddled with. After finishing the 300 km fuel economy run, all of the cars had to top up again while the marshalls check each vehicle's fuel consumption.

I can attest with the forester figures, did that pero la union to pque, yes lots of cruising,

[goodtj]

i think i know why toyota did not include vios/avanza
they have shitty fuel consumption

Im impressed with the Cayenne. It gets the same as a Montero or Fortuner despite being considerably bigger.

Then again, its P6m.

You don't cheat by refueling en route.

Especially not when you're in a convoy.

The easiest (and most effective) way to cheat is to simply shake the car during the fill-up so more fuel goes in.

Or, you can pre-prep the car by filling it to the brim, then shaking it, then refilling to the brim at a stop close to the official launch point. That ensures you have at least a few liters margin extra when they do the "official" top up.

This is how cheaters get the 30-40 km/l figures in contests.

I did 27 km/L with my Vios 1.3 once, but when I reran the test on a longer route it was only 21.26 km/L.

The only way to be sure, really, is multiple fills.

Like I did in the last Aero-Vios article:


http://www.topgear.com.ph/features/f...g-a36-20160402
(pimping it!)

If you're only doing single runs, and if you DON'T put the fuel in right away, you get A LOT of questionable fills. Turn the car off before the fill and turn it on again? That fuel rail dumps. Voila, you have an extra two or three liters back in the tank, so the fill comes up short (saw this happen all the time with my Lynx. Saw it at an eco-run with VW). Let the car cool down too much or sit too long or hit too many bumps? The tank burps and you lose a few liters because there's now more space. You MUST do the run, fill right away, then do the next, fill right away, and so on and so forth. Don't brim it, either. Because then air pockets and the evaporator hose make a hash of figures... (when we did economy tests for a tire manufacturer, it took TWO DAYS to fill an Innova completely to the brim... they topped the tank off four or five times and let the fuel settle overnight!)

The most consistent way, really, is to rely on the auto-stop, and to use a slow pump so it won't trigger prematurely.

I've seen the AAP-audited runs. Still very, very questionable, with lots of room for cheating.

To ensure accuracy, I did six runs. After the first run, the economy stabilized, because each fill was "like-to-like"... same car condition, tank condition, temperature, etcetera. Even with the short runs and small loads, the consistency was good enough that I was reasonably sure my results were valid. More valid, at least, than the full-tank to full-tank tests that others do.

As an aside, the stock 1.3 AT in my test got about 18.5 km/l, all highway. But the manual did about 22 km/l, straight 80 km/h running (speed verified by GPS... speedometer claimed 85+)

-

I believe the DOE should do it my way. Do 50 kilometer loops. Five of them. Refill the car after each and every loop. Each car's "witness" must carry a dash cam with GPS speed readout, for proper documentation.

Once the data is collected, throw out the "jokers" (high and low) and average the three middle runs. Or better, go for the median run, instead, so that wildly inaccurate fills don't affect the reading. You can close off two tollgates along the NLEX, two of the lesser used ones, and have guards stationed there so the cars don't have to stop.

Or even better, open up U-Turn loops specifically for the cars. And if you want to make the runs more realistic, shorten the loops. Make the tollgates just ten kilometers apart, so you have more acceleration-deceleration events.

My technical fees are very reasonable. DOE, call me.

They should rerun the test and change the route.

I suggest Makati CBD to Balintawak via Edsa on a Friday night.

[QUOTE=viper888;2735348]They should rerun the test and change the route.

The tests could be full of cheats.

The best method would be to run the engine from an external tank (e.g. a 4 gal water container. Since the cars will be in a convoy, malalaman kung sino ang unang titirik. Ang pinakamalayong malalakbay ay panalo.

Another option: itest ang fc sa up-vrtl, mahal nga lang ang bayad. P25k/car in 2014. However, vrtl refused to give us a 'detailed analysis' regarding the test, kaya, bahala ka sa interpretation mo. Very unscientific!

FYI, the AVL equipment from Austria cost millions, what, no detailed analysis? Sayang pera.

[oliver1013]

XT kaya yung Forester?

[MR_BIG18]

I think not sir

[weisshorn]

I still don't believe the FC figure of isuzu pick up.

Yup why? Bakit di sinama ang Vios pinaka popular sa masa.

The Hyundai Accent diesel did 29 kms/lit, a figure only half that claimed by HARI last year. HARI, what can you say about that now?
