Colorado home charging cost for the 2026 Rolls-Royce Spectre (22 inch Wheels)

At Colorado's residential electricity rate of 16.65¢/kWh, a 2026 Rolls-Royce Spectre (22 inch Wheels) (rated 43.6 kWh per 100 miles by the EPA) costs $7.27 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home is much cheaper than gas here: 54.6% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Rolls-Royce Spectre (22 inch Wheels) costs roughly $1,090 a year to charge at home in Colorado, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,313 a year.

What one full charge costs

Covering the 2026 Rolls-Royce Spectre (22 inch Wheels)'s EPA-rated 277-mile range takes about 120.9 kWh, which costs about $20.13 at Colorado's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 13,725 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Rolls-Royce Spectre (22 inch Wheels) alone ranks 340 of 400 models for efficiency; Colorado alone ranks 30 of 51 states for electricity price.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Colorado electrician to quote the install before this math becomes a real decision.
