The Subaru Uncharted is rated 308 miles on the EPA test, the Volvo C40 297. A 10–80% stop takes 28 minutes in the Subaru Uncharted and 34 in the Volvo C40. Every figure below names the version of the car it belongs to, and the three tools further down turn the same numbers into a charging race, a road trip and a yearly bill.

The short answer
The Subaru Uncharted is rated 308 miles against 297 — 11 miles, 4% further. It uses 25.7 kWh to cover 100 miles where the Volvo C40 needs 31.5.
A 10–80% stop takes 28 minutes in the Subaru Uncharted and 34 in the Volvo C40. On a 50 kW post it is 45 and 63 minutes, so most of the advantage disappears at a slow site.
The Volvo C40 makes 300 kW against 124.
Which one, in one line
Pick the Subaru Uncharted ifit wins on range (308 mi against 297), running cost (25.7 kWh per 100 miles against 31.5), charging (28 minutes against 34).
The priceNeither car has a US list price in the sheet yet, so nothing here claims an MSRP or a monthly payment.

Charging, raced
Charging speed is a station number and a car number, and the smaller one wins. Set the post and both cars fill against the same clock — the interesting part is not who wins, it is how much of the gap a slow post takes away.
Each car is modelled on its own published 10–80% time, which gives an average power over that window: 81 kW for the Subaru Uncharted, 93 kW for the Volvo C40. A post above that average changes nothing; a post below it sets the pace.
At 150 kW, going from 10% to 80% takes 28 min in the Subaru Uncharted and 34 min in the Volvo C40 — a gap of 6 minutes. Both cars are limited by their own packs at this post, so a bigger station would change nothing.
Every figure
A tick marks a figure that is simply more useful — more range, less energy per mile, a faster stop. Rows without a tick are different, not better: a bigger battery, a longer wheelbase and a wider body are all trades, and this page does not pretend otherwise.

How to read the mixed rows. Range and efficiency come from one EPA row — the longest-range version of each car's current model year, not the longest range it has ever been rated at. Battery, charging and the catalogue dimensions come from the catalogue's headline record, which is not always the same trim. Each of those rows names its trim where the two disagree, and the model pages carry the full per-trim table.
What the cold row is not. “Range left in the cold” is the catalogue's modelled cold-highway figure as a share of its mild-urban one — a European model, not an EPA test in US weather. It is shown as a share rather than in miles so it cannot be mistaken for a US range rating.
Euro NCAP is the European crash programme; NHTSA and IIHS ratings are not in this dataset and are not claimed here. Warranty terms are the catalogue's kilometre figures converted to miles, so read them as indicative until a US warranty source replaces them.
Your numbers
Two questions decide most purchases: how often you stop, and what the year costs. Both are arithmetic on the figures above, so change the inputs and the answer changes with you.
Starts full, arrives at 10%, charges back to 80% at each stop, and assumes a highway range of 85% of the EPA figure.

Energy at the wheels from the EPA label, priced at the tariff you pay. Home charging is usually cheaper than the directory's median.
$9 per 100 mi
$11 per 100 mi
The trip model ignores charger detours, queueing and the last 10% of the pack, which is slow on both cars. The yearly cost is energy only: no session fees, no idle fees, no home-charger installation, and no petrol car to compare against.
Your priorities
There is no single winner, only a winner for a set of priorities. Move the sliders and the weighting changes — nothing here is a magazine score, and the page never hides the numbers it is built from.
Weighted result
wins 3 of 6 measures on these weights
Each measure is scaled between the two cars, so a weight of 5 means “this is the thing I care about” and 0 means “I do not care at all”. The scores are relative, not a rating out of ten.
Questions
Every figure here comes from the same data as the rest of the page. Where the data cannot answer, the page says so instead of guessing.
Still unsure about a term? The charging glossary covers the rest of them.
The Subaru Uncharted. The Subaru Uncharted is rated 308 miles and the Volvo C40 297, each on the longest-range version of its current model year — 2027 Uncharted and 2024 C40 Recharge respectively. EPA figures are lab scores from one standard test, not a promise for a cold morning or a steady 75 mph.
The Subaru Uncharted. Going from 10% to 80% takes 28 minutes in the Subaru Uncharted (150 kW peak) and 34 in the Volvo C40 (149 kW peak). At a slow post the station becomes the limit and the gap narrows, because the slower car is short of power rather than short of time.
Yes. Both list CCS1 for DC fast charging, so either car can use the same sites without an adapter. An adapter still cannot raise the power a car will accept.
The Subaru Uncharted, by about $699.85 a year at 12,000 miles and $0.35 per kWh. It uses 25.7 kWh per 100 miles against 31.5. That is energy only, at the wheels: session fees, idle fees and home-charger installation are not in it.
The Volvo C40: 14.3 cu ft of boot against 14.8 cu ft. Boot volumes are measured by different conventions between makers, so read the direction as reliable and the exact size of the gap as indicative.
Not yet — neither car has a US list price in the current dataset. When a price source covers both, price becomes one more row in the table and one more slider in the weighting tool.
Every figure on this page comes from the same records the Subaru Uncharted and Volvo C40 pages use. How the sources are chosen, and what a figure here never claims, is on the methodology page.
