Sources & assumptions

  • EPA fuel economy data — City / highway / combined MPG and MPGe baselines.
  • U.S. Department of Energy (fueleconomy.gov) — Vehicle efficiency and EV range references.
  • AAA gas price trends — Recent national and regional retail fuel averages.
  • EIA electricity rates — Average residential per-kWh prices used for EV charging.

We summarize publicly available data — no scraping, no external API calls. Figures are calibrated periodically; use the calculators above for your exact inputs.

Route personality

Standard interstate driveScenic mountain drive

Mountain West driving context

  • Mountain passes can require chains or AWD from November through April — check CDOT/UDOT before departure.
  • Elevation gain reduces gas MPG and EV range by 10–20% on climbs; you recover some on descents.
  • Cell coverage drops in canyons — download offline maps before you go.

City insights

Boise, ID

  • Government and event-day closures around downtown Boise can reroute traffic.

Bend, OR

  • Bend's elevation can shorten EV range and lower gas MPG on the way in.
  • Winter ski-season weekends bring heavy outbound traffic from Bend.

Best stops along the way

  • Pick a sit-down meal stop around the 2.5-hour mark to reset focus and avoid drive-thru fatigue.
  • Truck-stop plazas (Pilot, Love's, TA) reliably have fuel, food and clean restrooms every 60–90 miles.
  • Mountain pass viewpoints make great photo stops — but check brakes before long descents.

Seasonal notes

Winter

Snow, ice and chain-control zones from late November through March — carry an emergency kit.

Late summer / early fall

Western wildfire smoke can drop visibility and force I-5 / I-80 detours — check InciWeb.

Fall–Spring

Pacific Northwest rain is steady October–April; allow extra braking distance on I-5 and US-101.

Recommendations for this route

  • EV-suitable: a 250+ mile EV makes this drive on 1–2 fast charges.
  • AWD or all-terrain tires help in winter; check brake pads before long descents.
  • Run tires at the door-jamb PSI and pre-cool the cabin with AC on low — both add 1–3 MPG.

Is it cheaper to fly or drive?

Driving is almost always cheaper here — short flights cost more than fuel once you factor in airport parking, bags and a rental car.

A one-way drive uses about $37 in gas (28 MPG, $3.45/gal). A typical short domestic flight costs $80–$220 per person plus $30–$60/day for airport parking and any baggage fees.

Weather & best time

Late spring through early fall — winter snow can close passes and add hours to the drive.

  • • Mountain passes can see snow or ice from November through April — check road conditions before you leave.

Tolls

Mostly toll-free — you can drive this without a transponder.

Best vehicle

An SUV or all-wheel-drive crossover is ideal — better handling on mountain passes and storage for gear.

Driving difficulty
