What an EV really costs in Connecticut — any EV, any hybrid, any gas car

What is different about Connecticut's numbers

Home electricity here is 27.4¢/kWh, 48.4% above the 18.4¢ U.S. average (EIA, 2026-05), and regular gas averages $3.95/gal, 2.8% above the national $3.85 (AAA). Connecticut is one of 10 states charging no EV road-use fee, so an electric car here carries only the $40 base registration.

Run all 80 models that have their own cost page through the kernel at both rate sets and the average electric car's 5-year total in Connecticut lands $1,814 above its U.S.-average figure, while the average gas or hybrid car lands $510 below its own. Net effect: Connecticut widens the gap an EV has to close by about $2,324. Head-to-head that comes out as EVs taking 13 of 55 matchups at Connecticut rates against 14 nationally — we publish that whichever way it falls.

Ranked against the other 50 state rate sets by what the whole priced fleet costs to run, Connecticut is 40th cheapest for an electric car and 37th for a gas or hybrid one. Its residential rate has moved 26.8¢ → 32.2¢/kWh across the 24 months to 2026-04 (+20.1%); on a Tesla Model 3 Premium RWD that shift alone is about $1,196 more electricity over 5 years than the same car would have cost at the 2024-05 rate.

Across the 37 matchups where an electric car faces a gas or hybrid one, the median EV costs $16,146 more over 5 years than the gas or hybrid car it is matched against at Connecticut rates — against $13,751 more nationally. Connecticut widens it by about $2,395. The EV that comes closest here is the Rivian R1S Dual-Motor (Standard Pack) against the Cadillac Escalade, $13,150 ahead; the furthest behind is the Kia EV9 Light Long Range RWD (electric) against the Toyota Grand Highlander Hybrid LE FWD, $28,443 adrift.

Running cost, Connecticut prices: a Tesla Model 3 Premium RWD draws about $7.78 of electricity per 100 miles at home (charging loss included), against $13.18 of gas for a 30 mpg car. A gas car would need 51 mpg to match the EV's fuel bill here. That is the running-cost line only — depreciation and insurance are what usually decide the 5-year total, and they are why most of the matchups below still go to the gas or hybrid car.

Connecticut EV incentive: CHEAPR (CT Hydrogen and Electric Automobile Purchase Rebate) — Standard new BEV — up to $1,000, income and price caps may apply.

Matchups that change hands in Connecticut

Car insurance in Connecticut

Drivers in Connecticut spent an average of $1,394 a year on auto insurance — 8.8% above the $1,281 national average (NAIC, 2023, the latest published figure; a state average across all drivers, not a quote for any one car or driver, and premiums have moved since). Electric cars typically add about 42% on top of a comparable gas car, 18% for 2024-and-newer models (Insurify, June 2026, modeled at a standard driver profile).
