Gas vs EV Road Trip Cost — 2026 Fuel Price Reality Check

The same trip through three powertrains on Los Angeles→Las Vegas (270 miles, Nevada gas at $3.40) is the 2026 fuel-price reality check: a 24-mpg SUV pays $38.25 ($14.17 per 100 miles), the hybrid SUV (33.6 mpg) pays $27.32, while a Tesla Model Y (3.8 mi/kWh) on $0.35/kWh Superchargers pays just $24.87 ($9.21 per 100 miles). Verdict: the EV saves $13.38 per trip — about 35% under the gas SUV — and driving this route monthly would save roughly $161 a year. The gap lives or dies on the two prices: $2.90 Texas gas or a pricier charger can nearly erase it.

Gas vs EV Road Trip Cost — 2026 Fuel Price Reality Check

Inputs

Route

Los Angeles → Las Vegas: 270 miles. I-15 all the way: start on a full California tank to dodge $4.70 pumps, then fill in Nevada at $3.40.

Trip miles
Powertrain

Hybrids are modeled as a 1.4x efficiency uplift on the same gas class (a 24-mpg SUV becomes ~34 mpg) — they never touch a charger, so their bill is pure state gas price.

Your EV model (2026 efficiency)

≈3.8 mi/kWh — America's best-selling EV and this tool's default.

Fill-up state (2026 price per gallon)

The 2026 spread across the 10 top road-trip states runs from $2.90 in Texas to $4.70 in California — a 62% gap that alone can decide the gas-vs-EV question before you pick a car.

Fast-charging network (2026 rate per kWh)

≈$0.35/kWh 2026 average — the cheapest big road network, now open to NACS-adapted EVs.

Default scenario: LA → Las Vegas · 270 miles · Model Y · Supercharger $0.35/kWh · vs a 24-mpg SUV on $3.40 Nevada gas — edit inputs
Trip fuel cost — EV (Tesla Model Y)
$24.87
$9.21 / 100 mi
≈ 95 SAR (pegged rate)
Formula: gas = 270 mi ÷ 24 mpg × $3.40 = $38.25; hybrid = ÷33.6 mpg = $27.32; EV = 270 ÷ 3.8 mi/kWh × $0.35/kWh = $24.87.
The verdict

You are already on the cheapest powertrain for this route: the ev Tesla Model Y at $24.87 — the next best would add $2.45 per trip.

The verdict prices the same route through all three powertrains — nobody edits the route between rows — and annualizes the gap ×12 for the driver who runs this route monthly.

Gas — SUV @ 24 mpg (11.3 gal)$38.25 · $14.17/100mi
Hybrid — same class @ 33.6 mpg (8.0 gal)$27.32 · $10.12/100mi
EV — Tesla Model Y (71 kWh × $0.35/kWh)$24.87 · $9.21/100mi
Gas-vs-EV gap on this trip$13.38 (-35% gas vs EV)

The home-charging toggle assumes half your energy comes from your own meter at the 2026 residential average (~$0.16/kWh — you leave with a full battery and refill at home) and half from the selected road network. Network rates are 2026 published national averages per kWh and vary ±30% by site and state surcharges; membership pricing (EVgo, Electrify America Pass+) can shave 10-25%.

The 2026 spread across the 10 top road-trip states runs from $2.90 in Texas to $4.70 in California — a 62% gap that alone can decide the gas-vs-EV question before you pick a car.

How the gas-vs-EV trip calculator works

Enter your trip details to get travel figures based on current, -specific numbers.

  1. 1

    Step 1

    Pick a route (6 US corridors at real mileage) and a fill-up state among the 10 top road-trip states, priced $2.90-$4.70/gal at 2026 planning averages.

  2. 2

    Step 2

    Pick the powertrain: gas (5 efficiency classes), hybrid (a 1.4x uplift on the same class) or EV (5 models) — for the EV, choose a charging network (Tesla/EVgo/Electrify America) and flip the home-charging toggle if your meter feeds half the trip.

  3. 3

    Step 3

    Read the verdict: the trip cost through all three powertrains, the $/100mi comparison, the gap to the cheapest option, and the annualized savings ×12 if you drive this route monthly.

FAQs

Is an EV always cheaper on a 2026 road trip?

No — and sometimes the edge flips: on Dallas→Houston (240 miles) a 24-mpg SUV pays about $29.00 on $2.90 Texas gas, while a Model Y on Electrify America ($0.48/kWh) pays about $30.32 — the EV loses. On Tesla Superchargers ($0.35) it pays $22.11 and wins clearly. The rule: the cheaper your state's gas and the pricier your charger, the narrower the gap — occasionally negative.

How does the state gas-price spread change the math?

The 2026 range runs $2.90 in Texas to $4.70 in California — a 62% gap per gallon. A 24-mpg SUV costs $12.08 per 100 miles in Texas versus $19.58 in California. That is why leaving California on a full tank down I-15 is a strategy: filling in the cheap state alone can decide the gas-vs-EV question before you even pick the car.

How is the EV trip cost computed?

Miles ÷ (miles per kWh) × charger rate: a Model Y (3.8 mi/kWh) on the 270-mile Los Angeles→Las Vegas run needs 71 kWh, and at Supercharger pricing of $0.35 that is $24.87, or $9.21 per 100 miles. The same run in a 24-mpg SUV on Nevada's $3.40 gas costs $38.25 — $14.17 per 100 miles.

Where does the hybrid land in this comparison?

Right in the middle: we model it as a 1.4x efficiency uplift on the same gas class — a 24-mpg SUV becomes about 34 mpg (8.04 gallons × $3.40 = $27.32 on the Vegas run), between the SUV's $38.25 and the Model Y's $24.87. Its strategic edge is zero charging stops: on a 520-mile Denver→Salt Lake City haul the hybrid saves the time an EV spends parked at chargers.

At what mpg does a gas car tie an EV?

Use the breakeven formula: breakeven mpg = gas price × (mi/kWh) ÷ charger rate. On Nevada gas at a Supercharger: 3.40 × 3.8 ÷ 0.35 ≈ 37 mpg — an efficient 32-mpg compact still loses to a Model Y. But put the EV on Electrify America and breakeven drops to about 27 mpg, where the compact pounces back. That is the 2026 fuel-price reality check in one number.

Does home charging change the verdict?

Strongly: the home-charging toggle blends half your energy from your own meter ($0.16/kWh, the 2026 residential average) and half from the road network. A Model Y on the Vegas run drops from $24.87 (Tesla-only) to $18.12 blended — savings versus the SUV widen from $13.38 to $20.13 per trip, and from $161 to about $242 a year for a monthly driver. Home is the cheapest energy in the whole game.

Which US fast-charging network is cheapest in 2026?

Tesla Superchargers first at about $0.35/kWh (now open to other EVs via NACS adapters), then EVgo at about $0.42, then Electrify America at about $0.48. For a Model Y on the Vegas route that is $24.87 vs $29.84 vs $34.11 — network choice alone swings the gas-vs-EV gap from $13.38 down to $4.14. Membership plans shave another 10-25%.

What do heat and cold do to the gas-vs-EV math?

Cold is the EV's tax: below ~20°F expect 20-30% more kWh — the Model Y's $24.87 Vegas run climbs to about $31 in January. It still beats the SUV's $38.25, but the gap roughly halves. Summer is gentler: air conditioning draws far less than cabin heating, and gas and hybrid consumption wobbles far less across seasons.
