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.

2 DC fast-charges for most EVs

Assuming a realistic 230-mile highway range, plan 2 DC fast-charging stops. Tesla Superchargers and Electrify America have strong coverage on most US corridors.

Route personality

Long-distance interstate driveMetro-to-metroToll corridor

Northeast Corridor context

  • I-95, the NJ Turnpike, Mass Pike and Garden State Parkway are toll-heavy — budget $15–$40 each way.
  • Dense traffic between DC, NYC and Boston; avoid 7–10 am and 3–7 pm windows.
  • E-ZPass works across the entire Northeast and is essentially required for efficient driving.

City insights

Boston, MA

  • Boston traffic is heaviest 7–9 am and 4–7 pm — time your arrival around it.
  • Boston draws year-round visitors — book parking and lodging ahead in peak weeks.
  • MA uses electronic tolling — an E-ZPass / SunPass / TxTag transponder is worth it.

Washington, DC

  • Washington traffic is heaviest 7–9 am and 4–7 pm — time your arrival around it.
  • Washington draws year-round visitors — book parking and lodging ahead in peak weeks.
  • Government and event-day closures around downtown Washington can reroute traffic.

Best stops along the way

  • New York, NY sits near the midpoint — natural fuel, food and restroom stop.
  • Pick a sit-down meal stop around the 2.5-hour mark to reset focus and avoid drive-thru fatigue.
  • Scenic pull-offs and coastal overlooks add 15–30 min but break up the monotony on tourism corridors.
  • Truck-stop plazas (Pilot, Love's, TA) reliably have fuel, food and clean restrooms every 60–90 miles.

Seasonal notes

Winter

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

Recommendations for this route

  • EV-suitable: a 250+ mile EV makes this drive on 1–2 fast charges.
  • Pick up the correct toll transponder (E-ZPass / SunPass / TxTag) before you leave.
  • Split the drive across a meal stop or overnight — fatigue starts hurting reaction time after 5 hours.
  • 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?

For one or two people, driving usually wins on cost. Solo travelers with no luggage may find a budget flight cheaper once you add parking and meals.

A one-way drive uses about $57 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

Spring and fall offer the most comfortable driving conditions and lighter holiday traffic.

  • • Winter snow and salted roads are common between November and March.

Tolls

Tolls are likely on parts of the route — usually under $20 each way, but a transponder saves time.

Best vehicle

A mid-size sedan or hybrid is the sweet spot — comfortable for the distance with strong MPG.

Driving difficulty

Medium · 7 hr 30 min

High — swap drivers every 2–3 hours and consider splitting the drive over a meal stop.
