This is the Country's Most Fuel Efficient Vehicle


The results are in, and the Isuzu D-Max has emerged as the most fuel-efficient vehicle that participated in the recently conducted Fuel Economy Run organized by the Department of Energy (DOE), held in cooperation with Petron Corporation.

Recording a fuel consumption rating of 38.46 kilometers per liter (km/L), the D-Max 3.0 LS 4x2 M/T topped by a considerable margin the 70 vehicle models entered into the DOE mileage testing by 21 automotive companies operating in the Philippines. Among diesel-powered vehicles of all types and sizes – hatchback, sedan, MPV, pickup and SUV, the second-best rating recorded was a 29.41 km/L, which was achieved by a subcompact sedan model.

“The rating achieved by the Isuzu D-Max in the 12th Department of Energy Fuel Economy Run, which is far better than the already impressive figures recorded by much smaller vehicles, confirms what we have been imparting to the market all along: Isuzu models, and the D-Max in particular, are some of the most reliable, durable and fuel-efficient vehicles available in the Philippines,” said Isuzu Philippines President Hajime Koso.

“The results of the government’s fuel economy testing provide incontrovertible proof of Isuzu’s expertise in diesel engine technology,” he added.

Along with the D-Max, two other Isuzu models were certified as having exceptional fuel mileage. The Isuzu Crosswind 2.5 XT M/T managed to record a 20.76 km/L rating while the Isuzu mu-X 3.0 LS-A 4x2 A/T logged the second-best result among diesel-powered SUVs with a consumption of 23.53 km/L.

The D-Max’s benchmark-setting fuel economy rating is a result not just of proper driving techniques but also of vehicle specifications. These start with the D-Max’s large-capacity 3.0-liter engine that was to proven to be under-stressed in highway driving conditions. The engine’s combination of an advanced cylinder head design featuring low-friction roller bearings, large front-mounted intercooler that minimized power-robbing heat, common rail direct injection that optimizes fuel use during combustion, and Variable Geometry System (VGS) turbocharger helped in keeping fuel consumption to a minimum. Enhancing the performance of the Isuzu 4JJ1-TC (Hi) 3.0-liter engine is a five-speed manual transmission. The D-MAX’s powerplant combination is identical to the mu-X.

Both the D-Max and mu-X also boast of aerodynamic body designs as the two models have benefited from extensive wind tunnel testing at the Japan Railway Technical Institute – the same facility where Japan’s bullet train was developed. The resulting low drag coefficients of both models contribute in cutting their fuel consumption.

  1. This is the most efficient vehicle according to DOE but to many it has the weakest engine and sitting at Row 4 Section 4 in the class. You cannot even achieve a decent accelaration by pressing the gas pedal hard. In the end you burn more money for the fuel whilst being the most boring and last one to arrive at the destination !

    2. For heavens sake ! Its not all about the engine or acceleration! We dont care what you say! We dont care if the Chevrolet Colorado is the best ! People buy this car because they like it ! Have you even test drove ?!

    3. Hi AutoActiv. Go to YouTube and check out the comparo done by caradvice.au between the Holden Colorado 7 (Chevy Trailblazer) and the Isuzu MU-X. Both vehicles are quite good, but the Aussies chose the MU-X over the Colorado 7.

  2. Black smoke from all Izusu vehicles is the incontrovertible proof that Izusu engines are the number one pollutants and violator of the Philippine Clean Air Act !!!

    3. Man who are timid prefers frugality and cosmetic accessories. Those who lead prefers power and streght. CHEVY COLORADO is the way to go for only the brave and the adventurous. Into the harshest terrain and under most the hostile weather, trust only the rugged cross because "GM makes it DURAMAX" !!!.

  5. When it comes to fuel efficient, reliable diesels, Isuzu seems to be at the top of their game. The problem is how they achieve fuel efficiency and reliability. It's common knowledge that more fuel is needed to produce more power and I think this is why Isuzu engines don't produce that much power. They sacrifice higher power for less fuel consumption.

    Also, to achieve higher power probably means that Isuzu has to produce more sophisticated engines that can handle higher turbo boost, more air volume, increased fuel pump pressure, higher injection pressure, and an increased compression ratio. The kind of engines that can no longer be serviced in remote areas by local mechanics. Consider too that multi-grade lubricants and clean diesels essential for more sophisticated engines may not be available in remote areas. When Isuzu says reliability, they mean that their engines can be serviced by almost any mechanic, can use single grade lubricant, and can run on diesel fuel stored in a rusty overhead drum.

    I've got a 14 year old Isuzu crosswind xuv a/t with 260,000+ kms on the odometer. It's noisy, belches black soot when pushed hard, lacks power, and is slow. But, it doesn't consume a lot of diesel fuel and it is inexpensive to maintain. I give it an oil change (clean air filter, change the oil filter, etc.) once or twice a year when I feel that the engine shudders too much at idle. I've changed the a/t fluid twice. Changed the water pump once. Replaced the original aircon compressor last year when it finally gave up the ghost. Belts have been changed when they are almost worn, etc. I've basically neglected to give the engine regular maintenance, but it still lives!

    All throughout the constant neglect the engine has never failed to start (literally at the first flick of the key it starts) even when the temperature fell to single digits on a trip to Baguio. It has enough power to keep a constant speed of 40kph going up the steepest sections of Kennon Road loaded with 7 people and enough luggage for a short holiday. It will consume just Php500 worth of diesel from Katipunan, QC to Anvaya Cove in Morong (via Subic) and back at a constant speed of 90kph on NLEX and SCTEX. And, it has never overheated even in gridlocked midday traffic on EDSA with the aircon on full blast.

    If you want a powerful diesel engine, go for the 2.8 duramax in the chevy colorado/trailblazer or that 3.2 from ford. More refined diesels? Mitsubishi and Toyota would be your best bet. But for low cost of ownership, low fuel consumption, and sheer reliability go for an Isuzu.

    1. Mitsubishi and Toyota are best bets for more refined diesels??? You dumb ass ! I live in the States and among the diesel pickup trucks locally sold in our beloved phils only the Colorado with Duramax engine is permitted to be sold here in the US. Not even fords 3.2 Ranger is able to pass the feds strict emission standards.

    2. Hi. Thanks for your reply. Considering that you live in the states, you may not know that the 2.8 duramax diesel in its stock from here in South East Asia will not pass the strict emissions standard of the U.S. The reason why it is now available in the U.S. is because GM fitted a urea tank and injector system in U.S. spec models that break down the nitrous oxide in the exhaust gasses. You'll see the filler cap for the urea tank beside the fuel filler cap. Same goes for all VW diesels and the new Cummins V8 diesel in the Nissan Titan. Also, the ford ranger in diesel trim will soon be available in the U.S. Thanks!

    3. The Ford Transit can be fitted with the 3.2-liter in the USA. Check it out at: http://www.ford.com/trucks/transitvanwagon/specifications/engine/

    1. Ugok ! Temperature has nothing to do when starting the engine. Its only the ignition switch, state of charge of the battery and the starter motor that is needed to crank and start the engine !

    3. Hi AutoActiv. Thank you for your reply. I've got a 2 year old Mitsubishi Montero Sport GLX. My crosswind starts quicker than my montero even when the montero was brand new.

      By the way, have you seen the comparo done by caradvice.au between the Holden Colorado 7 (Chevrolet Trailblazer) and the Isuzu MU-X where the Aussies chose the MU-X over the Colorado 7? It's very informative. Again, thanks for your reply.

    5. Tama nga naman. Yon Duramax Colorado lang ang diesel pickup engine mula dyan sa pinas ang binebenta dito sa states. Mahigpit kasi dito ang regulasyon sa smoke belching. At ang kailangan ng mga 'kano un malakas ang hatak.

      Delete
    6. At pano naman naging relevant kung ano binebenta sa US at gusto nang kano? Eh magkaiba emission standards natin sa US. Kung magco-compare ka, tignan mo ibang bansa na EURO standard ang ginagamit ugok.

  7. You are right. Its only the Duramax Engine Colorado from among the trucks sold locally passed the Feds NVH and Emission standards.

    1. Yes, that's correct. The 2.8 duramax diesel in its stock form here in South East Asia will not pass the strict emissions standard of the U.S. The reason why it is now available in the U.S. is because GM fitted a urea tank and injector system in U.S. spec models that break down the nitrous oxide in the exhaust gasses.

    2. Isuzu has once again proven and offered the Filipino buyer of its unrivalled diesel expertise...Its passenger vehicles namely the MuX, the Dmax and the Crosswind are award winning masterpieces of Noise & Smoke Belching Technology !!!

    3. Hoy wag ka ganyan! Alam mo ba ang CROSSWIND ang pinaka safe sa lahat ng sasakyan? Ito ay top selling vehicle ng Isuzu sa pilipinas! At alam mo naman ang mga pinoy, kaligtasan ng pamilya ang uunahin!

    4. On safety, according to ASEAN NCAP all cars with no airbag are rated zero stars. The Adventure, Innova and Crosswind all belong to this group of "zero star in safety" as in itlog (o) talaga !

  9. GM uses the same Duramax diesel engine that was jointly developed with Isuzu.

  10. If you're gonna have an internet argument, know your facts please retard. Top of the line Innova has 6 airbags.

  11. I know Isuzu vehicles are really fuel efficient.... but, really, 38 km/l?

  12. According to my personal judgement, here is the most efficient vehicle. And i hope anybody not mentally ill would agree.

    Ladies and gentlemen, the most efficient vehicle is a 2- Feetlinder "Pedicab-di padyak". No fuel needed, only used oil for rust prevention. Sa palagay ko, Win-win tayong lahat dito, walang maitim na usok sa ating mga ilong. Mabuhay tayong lahat ! Mabuhay ang Pilipino !

  13. The best that i could get from my dmax is 23km/l and that is without passenger cruising at 70-90kph sa SCTEX. And that figure goes down a lot at the slightest sign of traffic. BS.

    ReplyDelete
  14. Even 23km/l is hard to believe. Based on experience the Ford Expedition FC is averaging 5km/l. As a rule of thumb, smaller Suv is 3x more econmical than that of a large Suv which amounts to 15km/l average fuel consumption at most..

    ReplyDelete
  15. A 3.0 liter engine that produces 38 kms./liter is completely fabricated! Specially when a government agency like the DOE conducting it. Among pick-ups that are being sold here this brand lags behind. There must be some mistake with the results or some hocus-pocus.
