vs
The Audi Q4 e-tron is rated 540 km on the WLTP cycle, the Mercedes-Benz EQB 536. A 10–80% stop takes 28 minutes in the Audi Q4 e-tron and 30 in the Mercedes-Benz EQB. Every figure below names the badge 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
Two close cars, and the differences are in the details.
1
The Audi Q4 e-tron is rated 540 km against 536 — 4 km, 1% further. It uses 16.1 kWh to cover 100 km where the Mercedes-Benz EQB needs 15.7.
2
A 10–80% stop takes 28 minutes in the Audi Q4 e-tron and 30 in the Mercedes-Benz EQB. On a 50 kW post it is 69 and 59 minutes, so most of the advantage disappears at a slow site.
3
The Audi Q4 e-tron makes 210 kW against 140.

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: 123 kW for the Audi Q4 e-tron, 99 kW for the Mercedes-Benz EQB. A post above that average changes nothing; a post below it sets the pace.
Mercedes-Benz EQBCCS230min
Audi Q4 e-tronCCS228min
At 150 kW, going from 10% to 80% takes 28 min in the Audi Q4 e-tron and 30 min in the Mercedes-Benz EQB — a gap of 2 minutes. Both cars are limited by their own packs at this post, so a bigger station would change nothing.
Every figure
The numbers, with the badge attached
A tick marks a figure that is simply more useful — more range, less energy per 100 km, a faster stop. Rows without a tick are different, not better: a bigger battery, a taller body and a heavier car are all trades, and this page does not pretend otherwise.

How to read the mixed rows. Range, efficiency, battery and charging come from one badge — the longest-range version of each car's current model year, not the longest range it has ever been rated at. The catalogue stores one record per badge, so where two figures come from different badges the row names the one it used.
What WLTP is not. It is a laboratory cycle at a fixed temperature, with the air conditioning off and a gentle acceleration profile. It exists so two cars can be compared on the same test, not so a driver can predict a highway run. Expect less on a 110 km/h trip, and less again in winter.
What this page does not claim. No ANCAP crash rating: the catalogue carries none, and a column of dashes would read like a failure rather than a gap. Prices are manufacturer list before on-road costs; the drive-away band appears only where the feed publishes one.
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 WLTP figure.

The year
Energy at the wheels from the WLTP 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
Audi Q4 e-tron
wins 6 of 7 measures on these weights
Audi Q4 e-tron83%
Mercedes-Benz EQB17%
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 connector guide covers the plugs, and the vehicle guide the rest.
Which has more range, the Audi Q4 e-tron or the Mercedes-Benz EQB?
The Audi Q4 e-tron. The Audi Q4 e-tron is rated 540 km and the Mercedes-Benz EQB 536, each on the longest-range badge of its current model year — MY26 45 Sportback and MY24–MY26 250+ respectively. WLTP is a laboratory cycle run at a fixed temperature with the air conditioning off, so treat the figure as a way to compare one car with another rather than a prediction for a highway run in summer.
Which charges faster?
The Audi Q4 e-tron. Going from 10% to 80% takes 28 minutes in the Audi Q4 e-tron (175 kW peak) and 30 in the Mercedes-Benz EQB (112 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 CCS2 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 EQB, by about A$30.00 a year at 15,000 km and A$0.50 per kWh. It uses 15.7 kWh per 100 km against 16.1. That is energy only, at the wheels: session fees, idle fees and home-charger installation are not in it.
Which has more space?
The Audi Q4 e-tron: 535 L of luggage space against 495 L, and 7 seats against 5. Makers measure boot volume by different conventions — some to the window line, some under the parcel shelf — so read the direction as reliable and the size of the gap as indicative.
Which is cheaper to buy?
The Audi Q4 e-tron is the cheaper of the two, listed from A$82,900 against A$90,000 for the Mercedes-Benz EQB — A$7,100 between the two starting prices. Both are manufacturer list prices before on-road costs, options and any incentive, so a dealer's drive-away number will differ.
