NREL’s Fleet Test and Evaluation Team recently completed a year-long technology evaluation of gasoline hybrid electric (gHEV) FedEx Express delivery trucks compared with conventional diesel vehicles. On drive cycles representing routes with fewer stops and accelerations, the gHEV trucks demonstrated similar fuel economy to the diesels.

The 2023 UX 250h runs on 87 octane and is EPA rated at 43 mpg city/41 highway/42 combined. The nickel-metal hydride (NiMH) battery is charged when applying the brakes or coasting. Our focus is on vehicles that offer the best fuel economy in their class, which leads us to emphasize electric cars, plug-in hybrids, hybrids and diesels.

Fuel economy for the 2022 UX 250h, which runs on 87 octane gasoline, is EPA rated at 41 mpg city/38 highway/39 combined, but in the Eco drive mode our time traversing Southern California highways covered 221 miles at an average of 42.7 mpg, and on short in-town runs I was getting in excess of 50 mpg. Your numbers may differ.

How does this sound: 100+ MPG in a regular vehicle? Finally, looking at the non-electric fuel, instead of using gasoline for long-trips, PHEVs could run on bio-diesel, cellulose ethanol, or other bio-fuels to further reduce greenhouse gases. At $3 for a gallon of gas, driving a non-hybrid car costs 8-20 cents/mile (depending on MPG).
