Charging a 2027 Rivian R1T Quad (20in AT) at home in California

In California, home electricity runs 33.17¢/kWh — put a 2027 Rivian R1T Quad (20in AT)'s EPA-rated 50.1 kWh/100mi against that and 100 miles costs $16.62, versus $16.02 for a gas car averaging 25.5 mpg. Here the math runs the other way: 3.7% more per mile than gasoline, because California's rate and this model's efficiency combine unfavorably.
