As a reminder, the 2025 DOE Fuel Eco Run marked the first time conventional combustion engine (ICE), hybrids (HEV), plug-in hybrids (PHEV), and battery electric vehicles (BEVs) ran together through the exact same route. In this case, the 154.5-kilometer route had the convoy driving from Petron TPLEX Northbound, turning around at the Rosario rotunda in La Union, and concluding at Petron TPLEX Southbound.

To level the playing field, the DOE adopted the km/Lge standard which measures consumption on a “kilometers per liter of gas equivalent.” While gas-powered vehicles have a 1 L to 1 Lge equivalent, diesel-fed vehicles, have a 1L diesel to 1.077 Lge conversion. Meanwhile, electric vehicles will have a 1 Lge to 8.89 kWh conversion.

Furthermore, to ensure fairness, all ICE and hybrid vehicles used either Petron XCS or Petron Turbo Diesel, while BEVs and PHEVs were supported by Petron EV charging stations and AC Mobility’s Power on Wheels mobile charger.

And while around 70 vehicles did take part in the fuel economy run only 50 vehicles from 15 manufacturers/distributors had their results officially posted. Those that passed on having their official results posted include BYD, Ford, Hyundai, Jetour, Kia, and Mazda. You can check the official list, ranked by km/Lge below.

As for some key takeaways from this year’s DOE Fuel Eco Run. One, the most energy efficient vehicles for this route aren’t diesels anymore, but battery electric vehicles. In fact, 8 out of the Top 10 are all BEVs. Tesla took the first and third spots, with Mini in second. Remarkably, the two outliers here were PHEVs with Chery fourth with their Tiggo rEV C-DM LE and Lynk & Co 01 PHEV in tenth spot.

Most efficient HEV went to the Civic RS e:HEV in 18th place overall, with the first runner-up being the MG ZS Hybrid+. If you are looking for the most efficient Toyota HEV, that would be the Lexus LBX in 21st or the Corolla Cross GR-S in 22nd.

When it comes to the most fuel-efficient combustion engine offering, that award goes to the Suzuki Dzire all the way in 17th place. However, it must be noted that this sub-compact sedan does still use some electrification support thanks to a 12-volt SHVS (Smart Hybrid Vehicle by Suzuki) system.

If you’re looking for the most fuel efficient vehicle that doesn’t have any electrification whatsoever, that goes to the Nissan Almera and its astounding 29.33 km/Lge rating in 19th place. Most efficient diesel? The Isuzu D-Max in 35th place.

Aligned with the Philippine Energy Plan, Republic Act (RA) No. 11285 or the Energy Efficiency and Conservation Act and RA No. 11697 or the Electric Vehicle Industry Development Act, the Eco Run underscores DOE’s strong commitment to policies that advance energy efficiency, sustainable transport, and energy security.

“This isn’t a race. It’s a demonstration of how different vehicle technologies perform under actual driving conditions. Our focus is on providing credible fuel economy data, not on who finishes first. By testing vehicles under real-world driving conditions, we are guiding Filipino consumers that energy efficiency is both practical and attainable,” said Energy Secretary Sharon S. Garin.

The DOE says that transportation is one of the country’s most energy-intensive sectors, accounting for 34 percent of total energy consumption. The results of this activity may serve as a benchmark for government agencies and local government units in procuring efficient fleet vehicles, in support of the government’s accelerated campaign under the Government Energy Management Program (GEMP). By shifting to more efficient vehicles and fuels, we can reduce greenhouse gas emissions, lessen dependence on imported fuel, and improve air quality for future generations.
