vs
The BMW i7 is rated 373 miles on the EPA test, the Mercedes-Benz EQS 443. A 10–80% stop takes 28 minutes in the BMW i7 and 26 in the Mercedes-Benz EQS. 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 Mercedes-Benz EQS turns the same electricity into more miles.
1
The Mercedes-Benz EQS is rated 443 miles against 373 — 70 miles, 19% further. It uses 35.5 kWh to cover 100 miles where the Mercedes-Benz EQS needs 29.6.
2
A 10–80% stop takes 26 minutes in the Mercedes-Benz EQS and 28 in the BMW i7. On a 50 kW post it is 95 and 94 minutes, so most of the advantage disappears at a slow site.
3
The BMW i7 is rated to tow 4,409 lb against 3,527 lb.
Which one, in one line
Pick the Mercedes-Benz EQS ifit wins on range (443 mi against 373), running cost (29.6 kWh per 100 miles against 35.5), charging (26 minutes against 28).
The priceThe Mercedes-Benz EQS is the cheaper to buy, listed from $89,950; both are US list prices before tax, delivery and incentives.

Charging, raced
Two cars, one post, same clock
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: 169 kW for the BMW i7, 181 kW for the Mercedes-Benz EQS. A post above that average changes nothing; a post below it sets the pace.
Mercedes-Benz EQSCCS131min
BMW i7CCS132min
At 150 kW, going from 10% to 80% takes 32 min in the BMW i7 and 31 min in the Mercedes-Benz EQS — a gap of 0 minutes. At this post the station is the bottleneck for both cars, so they fill at much the same rate and the gap comes down to how much energy each one needs.
Every figure
The numbers, with the version attached
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
What this pair costs you, on your drive
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.
The drive
Starts full, arrives at 10%, charges back to 80% at each stop, and assumes a highway range of 85% of the EPA figure.

The year
Energy at the wheels from the EPA label, priced at the tariff you pay. Home charging is usually cheaper than the directory's median.

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
A verdict you can argue with
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 5 of 7 measures on these weights
BMW i711%
Mercedes-Benz EQS89%
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
Short answers, then the reasoning
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.
Which has more range, the BMW i7 or the Mercedes-Benz EQS?
The Mercedes-Benz EQS. The BMW i7 is rated 373 miles and the Mercedes-Benz EQS 443, each on the longest-range version of its current model year — 2027 i7 xDrive50 Sedan (20 inch Summer Tires) and 2027 EQS 500 4matic respectively. EPA figures are lab scores from one standard test, not a promise for a cold morning or a steady 75 mph.
Which charges faster?
The Mercedes-Benz EQS. Going from 10% to 80% takes 28 minutes in the BMW i7 (250 kW peak) and 26 in the Mercedes-Benz EQS (330 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.
Do they use the same plug?
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.
Which is cheaper to run?
The Mercedes-Benz EQS, by about $704.64 a year at 12,000 miles and $0.35 per kWh. It uses 29.6 kWh per 100 miles against 35.5. That is energy only, at the wheels: session fees, idle fees and home-charger installation are not in it.
Which has more space?
The Mercedes-Benz EQS: 17.7 cu ft of boot against 21.5 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.
Which is cheaper to buy?
The Mercedes-Benz EQS is the cheaper of the two to buy, listed from $89,950.00 against $106,875.00 for the BMW i7 — $16,925.00 between the two starting prices. Both are manufacturer list prices before sales tax, destination and delivery charges, options and incentives, so a dealer's number will differ; these are US list prices from the manufacturers' own price lists, not the catalogue's European figures.
