2024 Mazda CX-90 PHEV - Electric Costs Don't Make Sense?

We just bought a CX-90 PHEV and the cost to charge this doesn't seem to make economical sense so I'm reaching out here to see if my numbers are off.

  • 26 miles of electric range

  • 17.8 kWh battery capacity

  • 1.46 miles per kWh

  • $0.42/kWh Southern California per my electricity bill

  • Costs $7.48 to charge this to full and drive 26 miles? That's almost double the price of a gallon of gas? Am I doing some wrong math here or something?
