Subaru Solterra Premium AWD (2023-2025) — Road Trip Charging Cost & Stops

Subaru Solterra Premium AWD (2023-2025) charging specs

WattWay treats 64 kWh as the usable pack — the energy you can actually spend — and derives 3.56 mi/kWh from the EPA range against it. Profiles are split by spec generation, so this entry covers only the 2023-2025 model years, where the battery, range and charge rate are constant. Other model years of the Solterra Premium AWD are listed separately on the all-EVs page.

What a charge costs on each network

A 10-80% session on this car moves 44.8 kWh. Below is what that same energy costs on every network WattWay prices, cheapest first, using its 2026 reference rates.

The spread is the whole point: the same 44.8 kWh costs $8.96 on OUC and $26.43 on Blink — a difference of $17.47 for identical electricity. Over the 6 stops a 1,000-mile trip needs, picking well is worth about $92.08. Municipal and utility-run networks are cheapest but exist only in a few metros, so a realistic plan mixes them with whatever is actually on your route.

How long a Subaru Solterra Premium AWD takes to charge

Charge time is set by the slower of two things: the car's 100 kW ceiling and the stall's output. A 100 kW car gains nothing from a 350 kW stall beyond 100 kW, and a 50 kW stall throttles every car on the lot. The power column is the average the model assumes across the whole window — 85% of whichever limit binds — not the peak either side can hit, which is why the times below follow from it directly.

Miles per minute is the figure to compare across cars: it folds charge rate and efficiency together, so a big efficient pack at 150 kW can beat a thirsty one at 250 kW. Read these as a best case. They assume the car averages about 85% of its nameplate power for the whole 10-80% window, on a warm battery, at a stall running at full output. Real sessions are commonly 1.5-2× longer: cars with steep charge curves fall well below their peak long before 80%, a cold pack can halve the rate if you haven't preconditioned, and shared or derated stalls are routine. Use these to compare cars against each other, not to schedule your arrival.

Stops and cost by trip length

Leaving at 80% and arriving on the 10% reserve, each charge buys about 159 miles in this car. Cost columns show the cheapest and most expensive networks as a realistic range.

Charging time is computed from the energy actually bought, not from whole sessions — the last stop is nearly always a partial top-up, so counting it as a full 10-80% charge would overstate the total. The cost column is likewise what you buy at chargers: the first 159 miles run on the charge you left home with, so a trip shorter than that shows nothing bought en route. This is also the idealized version — evenly spaced chargers, every one working, no detours. A real route has gaps, and the charger 40 miles ahead may be cheaper than the one you can just barely reach. Run your actual route through WattWay to get stops placed against real charger locations and prices.

Do charging memberships pay off for this car?

Every subscription is the same bet: a fixed monthly fee against a per-kWh discount. For the Solterra Premium AWD, here is how many 10-80% sessions per month it takes to break even.

Break-even counts assume you charge on that network exclusively, which nobody does. Treat them as a floor: if a road trip alone clears the break-even, the plan is worth buying for that month. WattWay applies whichever memberships you select when it prices a route.

Subaru Solterra Premium AWD (2023-2025) charging questions

How much does it cost to fast-charge a Subaru Solterra Premium AWD (2023-2025)?

A 10-80% DC fast charge moves about 44.8 kWh into the 64 kWh pack. At OUC's $0.20/kWh that is about $8.96; at Blink's $0.59/kWh it is about $26.43. Which network you stop at therefore changes the price of the same electricity by roughly $17.47 per stop.

How long does a Subaru Solterra Premium AWD (2023-2025) take to charge on a road trip?

From about 32 min for 10-80% on a stall that can deliver the car's full 100 kW with a warm battery — that is the best case, and real sessions are commonly half again to twice as long once the charge curve tapers, the pack is cold, or the stall is shared. Charging past 80% is slower still, which is why the cheapest plan is usually more short stops rather than fewer long ones.

How far can a Subaru Solterra Premium AWD (2023-2025) go between charging stops?

Roughly 159 miles of highway driving per 10-80% charge, from 228 miles of EPA range and 3.56 mi/kWh. Cold weather, sustained high speed, headwinds, elevation gain and a loaded vehicle all cut that figure, sometimes by 30% or more.

How many charging stops does a Subaru Solterra Premium AWD (2023-2025) need on a 500-mile trip?

About 3 DC fast-charge stops, assuming you leave at 80% and arrive on the 10% reserve. The charging you buy on the way costs roughly $19.13 on OUC and $56.43 on Blink. That excludes the first 159 miles, which come out of the charge you left home with at a residential rate.
