On a drive cycle representing routes with frequent stops and accelerations, the gHEV trucks exhibited a 20% improvement in fuel economy. On drive cycles representing routes with fewer stops and accelerations, the gHEV trucks demonstrated similar fuel economy to the diesels. Ah NiMH battery pack. Click to enlarge.

Fuel economy was similar between the gHEVs and diesel vehicles, except for the highest kinetic intensity drive cycle where the hybrid exhibited ~20% higher fuel economy. NREL collected and analyzed data for in-use fuel economy and fuel costs, maintenance costs, total operating costs, and vehicle uptime.

MG 1 starts the gasoline engine and charges the nickel-metal hydride (NiMH) battery, while MG2 drives the front wheels and regenerates the battery during braking and coasting, and MGR drives the rear wheels and also regenerates the battery. The EPA rates fuel economy at 31 mpg city/28 highway/30 combined.

The trick to getting the highest fuel economy in a hybrid is learning how to drive it efficiently. 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

This is from "Commercializing Plug-In Hybrids" (pdf), the current CalCars 24-slide presentation about PHEVs available along with other documents at CalCars Downloads. Agrees on environmental and economic benefits, though some presentations backtrack on that; says batteries need further development before commitment to mass-production.
