You don’t buy an Audi Q4 e-tron to hypermile in the right lane; you buy it because you want a quiet, upscale compact SUV that can pull family duty and still look at home in the valet line. But the moment you merge onto the interstate you discover the truth EV owners learn fast: **highway range is where the real story begins**. The question is simple, what’s the Audi Q4 e-tron real‑world range on the highway, especially around 70 mph?, and the answer is a little more nuanced.
EPA vs. reality
Q4 e-tron batteries, trims, and EPA range at a glance
Before you can predict real‑world highway range, you need to know **which Q4 e-tron you’re actually talking about**. Audi has shuffled names and powertrains since launch, but from a range perspective there are really two batteries and a few key trims that matter for U.S. buyers.
Audi Q4 e-tron EPA range by key trims (recent U.S. models)
Approximate EPA ratings for late‑2023 to 2025 Audi Q4 e-tron models sold in North America. Exact figures vary slightly by wheels and body style (SUV vs. Sportback).
| Model year / trim | Drive | Usable battery | EPA combined range | EPA highway range (where listed) |
|---|---|---|---|---|
| 2021–2023 Q4 40 e-tron | RWD | 77 kWh | ~241 mi | ~230 mi (est.) |
| 2024 Q4 40 e-tron | RWD | 77 kWh | 265 mi | ~240 mi (est.) |
| 2024 Q4 50 e-tron quattro (SUV) | AWD | 77 kWh | 236 mi | , |
| 2024 Q4 55 e-tron quattro (Sportback) | AWD | 77 kWh | 258 mi | , |
| 2025 Q4 45 e-tron (new motor) | RWD | 77 kWh | 288 mi | 260 mi (EPA highway) |
| 2025 Q4 55 e-tron quattro | AWD | 77 kWh | 258 mi | ~240 mi (est.) |
Use this as a starting point; your actual highway range will usually be lower at steady interstate speeds.
Quick takeaway
Real‑world highway range at 70 mph
Here’s where lab numbers meet the ugly aerodynamics of a two‑box SUV. Independent U.S. 75‑mph tests on the Q4 e-tron show exactly what you’d expect from a compact, bluff‑front luxury EV: **solid efficiency around town, noticeably thirstier at speed**.
What real 70–75 mph tests show
If you boil it down, for **late‑model Q4 e-trons with the big pack (77 kWh usable)**, a good planning rule for U.S. interstate driving looks like this:
- Q4 45 RWD (2025+): plan on **210–230 miles** at a true 70 mph in mild weather
- Q4 40 RWD (earlier years): roughly **190–210 miles** at 70 mph
- Q4 50/55 quattro SUV: closer to **170–200 miles** at 70–75 mph, depending on wheels and temperature
- Sportback versions: nudge those numbers up by ~10–15 miles thanks to better aerodynamics
Winter is a different car
Why highway range always trails the brochure
The Q4 e-tron rides on VW Group’s MEB platform, the same basic skate‑board as a Volkswagen ID.4. It’s competent, efficient enough, and not particularly magic. On the highway, physics calls the shots, and the Q4 checks several boxes that work against ultimate range at speed.

How the Q4 e-tron’s highway range compares to rivals
In the compact luxury EV SUV class, the Q4 e-tron sits squarely in the middle lane. It’s not a range monster, but it’s hardly a parched relic either. Think of it as **comfortably average**, which is both the compliment and the criticism.

| Model | Drive | Usable battery | EPA combined range | Likely 70–75 mph range |
|---|---|---|---|---|
| Audi Q4 45 e-tron (2025) | RWD | 77 kWh | 288 mi | ~210–230 mi |
| Audi Q4 55 e-tron quattro | AWD | 77 kWh | 258 mi | ~180–210 mi |
| Cadillac Optiq single‑motor | RWD | ~85 kWh | ~317 mi | ~230–250 mi |
| Mercedes EQB 300 4Matic | AWD | ~70 kWh | 245 mi | ~170–190 mi |
| Volvo XC40 Recharge RWD | RWD | 78 kWh | 293 mi | ~210–230 mi |
| Tesla Model Y Long Range | AWD | 75 kWh | 310+ mi | ~230–260 mi |

Where the Q4 shines anyway
How to stretch your Q4 e-tron’s highway range
You can’t change physics, but you can coach it. The Audi Q4 e-tron quietly rewards drivers who are gentle with speed and thoughtful with planning. A few habits go a long way.
Practical ways to add 20–40 miles of highway range
1. Treat 70 mph as your ceiling, not your average
Dropping from the mid‑70s to a true **68–70 mph cruise** is often the single biggest lever you control. Expect noticeably slower battery percentage drop over distance.
2. Use Audi’s efficiency mode when it makes sense
The Q4’s efficiency and comfort modes trim throttle response and tweak climate settings. They aren’t magic, but they can **shave several kWh per 100 miles** on long runs.
3. Precondition while plugged in
On cold or hot days, use the myAudi app or in‑car timer to pre‑heat or pre‑cool while the car is still charging. That way you **spend less battery getting the cabin comfortable** once you hit the highway.
4. Pack smart: aero beats aesthetics
Roof boxes, bike racks, and open windows are range kryptonite at speed. If you can carry it **inside the car or on a hitch rack tucked behind the body**, do that instead.
5. Watch elevation and wind in your planner
Most modern route planners, including third‑party apps, factor in elevation. If you’re driving into a stiff headwind or climbing all day, **plan shorter legs between fast chargers**.
6. Charge in the efficient middle band
The Q4 charges, and drives, most efficiently between roughly **10% and 70–80% state of charge**. On road trips, it’s often faster overall to make more, shorter fast‑charge stops within that window.
Buying a used Q4 e-tron? Range & battery health questions to ask
Because the Q4 e-tron went on sale in the U.S. for the 2022 model year, the oldest examples are now entering prime **used EV territory**, where range paranoia and bargain hunting meet in a dark alley. The good news: early data suggests the Q4’s battery chemistry is holding up well so far. The bad news: you still need to be picky.
Key range questions for a used Q4 e-tron
- Which trim and battery? Confirm whether it’s a 40, 45, 50 or 55, SUV or Sportback. That alone changes real‑world highway range by 30–40 miles.
- Wheel and tire setup? Big 21" wheels with sporty rubber look great but **hurt efficiency**. Ask if a smaller wheel set is included.
- Highway vs. city history? A car that lived its life as a 80‑mph commuter may show slightly more degradation than a mixed‑use car.
How Recharged helps de‑mystify range
Every EV sold through Recharged includes a Recharged Score Report with a verified battery‑health snapshot and fair‑market pricing. Instead of guessing from a dash readout, you see how the pack actually performs, based on proper diagnostics.
If you’re comparing two used Q4 e-trons, a 2022 Q4 40 and a 2024 Q4 55 Sportback, say, our EV specialists can walk you through how each will behave on your specific commute and road‑trip patterns, not just what the badge claims.
Don’t buy on EPA range alone
Planning road trips: charging strategy for the Q4 e-tron
The Q4 e-tron’s DC fast‑charging isn’t class‑leading on paper, older versions topped out around 150 kW, newer ones around 175 kW, but when you plan legs around its **true highway range**, it becomes an easy road‑trip companion.
A simple, low‑stress road‑trip template
Works for most 77 kWh Q4 e-trons in the U.S.
Leg length & charge windows
- Plan legs of **120–150 miles** between fast chargers in mild weather.
- In winter, shorten that to **90–120 miles**.
- Arrive near **10–20%**, leave around **70–80%**, the quick part of the charging curve.
This keeps you in the Q4’s most efficient SoC band and avoids painful last‑10% charging times.
Network strategy & apps
- Use multiple apps (ChargePoint, Electrify America, PlugShare, your utility’s app) to verify station status.
- Give preference to sites with **4+ stalls** for redundancy.
- If you’re buying through Recharged, ask our team to help you map a sample road trip for the Q4 you’re eyeing, we do this every day.

Frequently asked questions
Bottom line: what to expect from the Q4 e-tron on the open road
If you’re chasing maximum highway range at all costs, the Audi Q4 e-tron is not the obvious winner in its class. But if you want a **refined, compact luxury SUV that will quietly knock out 180–220‑mile highway stints**, then top up over coffee and do it again, it makes a strong case for itself, especially on the used market, where pricing has become far more approachable.
The working number to keep in your head is simple: **plan your Q4 e-tron around 70–75% of its EPA rating at 70–75 mph**, and you’ll almost never be surprised. From there, the usual common sense applies, watch the weather, keep an eye on speed, and don’t let the battery live at the extremes. If you’d like help finding a Q4 e-tron whose real‑world range matches your life, Recharged can pair battery‑health diagnostics, pricing data, and expert EV guidance into one clean, digital buying experience.
