If you’re looking at a 2022 Mercedes EQS, you’ve probably heard the headlines: huge battery, big luxury, serious range. But the **2022 Mercedes EQS range test** story is more interesting than a single EPA number. In independent highway testing, the EQS has quietly become one of the few EVs that can *beat* its window-sticker rating, something range‑anxious shoppers should absolutely pay attention to, especially in the used market.
Quick take
Why the 2022 EQS range test matters
Range still makes or breaks an EV purchase. On paper, the rear‑drive EQS 450+ was one of the longest‑range EVs you could buy in 2022, trailing only a few trims of the Tesla Model S, Tesla Model 3, and Lucid Air. But EPA range is a mixed‑driving lab number. What you really want to know is: *If I set the cruise control and drive like a normal human, how far will this car actually go?* That’s where standardized real‑world highway tests come in.
For used‑EV shoppers, this matters even more. A three‑ or four‑year‑old luxury EV like the EQS can offer serious value, if its **battery health** is strong and its real‑world range still lines up with those early tests. That’s exactly the kind of thing a Recharged Score battery report is built to verify for you.
Key 2022 Mercedes EQS range numbers at a glance
Battery, trims, and official EPA range
Every 2022 Mercedes EQS sedan, regardless of trim, is built around the same large **107.8 kWh lithium‑ion battery** (usable capacity). The big differences in range come from the drivetrain and power output:
2022 Mercedes EQS sedan: EPA range by trim
Official EPA combined range ratings for the 2022 EQS lineup.
| Trim | Drivetrain | Power (hp) | EPA Range (mi) | EPA MPGe (comb.) |
|---|---|---|---|---|
| EQS 450+ | RWD, single motor | 329 | 350 | 95–97 |
| EQS 580 4Matic | AWD, dual motor | 516 | 340 | 95 |
| AMG EQS | AWD, performance tuned | 649 (up to ~751 boost) | 277 | 76 |
All trims share the same battery; motors and weight change the range story.
If you care primarily about **maximum range**, the EQS 450+ is the hero of the lineup. The EQS 580 and AMG EQS trade some of that distance for all‑weather traction and much stronger acceleration.
RWD vs AWD: which EQS goes farther?
InsideEVs 70 mph range test: EQS 450+
InsideEVs runs one of the cleanest EV range protocols around: charge to 100%, set the cruise control at 70 mph, and loop on the same highway until the battery is essentially empty. In May 2022, they put a U.S.-spec **2022 EQS 450+** through that test.
- EQS 450+, rear‑wheel drive, 20‑inch wheels
- Speed held as close to 70 mph as traffic allowed
- Eco driving mode selected; tires at factory‑recommended pressures
- Weather mild; mostly dry highway interstate loops
InsideEVs 70 mph range test: segment results
How the EQS 450+ used its battery from full to empty in InsideEVs’ highway test.
| State of charge segment | Miles driven in segment | Efficiency (mi/kWh) | Cumulative miles |
|---|---|---|---|
| 100% → 75% | 92 | 3.46 | 92 |
| 75% → 50% | 101 | 3.58 | 193 |
| 50% → 25% | 97 | 3.58 | 290 |
| 25% → 0% | 105 | 3.67 | 395 |
Efficiency stayed impressively consistent as the pack discharged.
They pulled off for a charger at 1% state of charge, with the EQS still showing a sliver of range left, and rolled the final few miles at about 50 mph. The trip meter stopped at **395 miles**, which is 45 miles past the 450+’s 350‑mile EPA rating, about a **13% over‑achievement**.
Why this test matters
Car and Driver highway range: EQS 580
Car and Driver runs its own 75‑mph highway range loop. They tested the dual‑motor **2022 EQS 580 4Matic** and recorded **350 miles of range** at that higher speed, again, slightly *beating* the car’s 340‑mile EPA rating. That’s unusually strong performance for a heavy, all‑wheel‑drive luxury EV.
EQS 450+: range specialist
- EPA: 350 miles
- Real highway: ~395 miles at 70 mph in independent testing
- Rear‑drive, less drivetrain loss
- Best choice if you care most about distance per charge
EQS 580: power with only a small penalty
- EPA: 340 miles
- Real highway: ~350 miles at 75 mph in testing
- All‑wheel drive and much stronger acceleration
- Gives up surprisingly little range compared with the 450+
Mileage may vary, literally
Real-world vs EPA: what you should actually expect
So what does all this mean when you’re simply trying to plan a road trip or your daily commute? Think of EPA range as an optimistic but honest estimate for mixed city/highway driving in good weather. Real life adds variables: cold snaps, headwinds, traffic, elevation, and how hard you lean on that right pedal.
Typical 2022 EQS range expectations
Realistic ranges for different kinds of driving, assuming a healthy battery.
City & suburban mix
Lots of stop‑and‑go, speeds under 50 mph, mild weather.
- EQS 450+: 320–360 miles
- EQS 580: 300–340 miles
Steady highway cruising
Cruise set around 70–75 mph, light traffic, mild temps.
- EQS 450+: 360–395 miles
- EQS 580: 320–350 miles
Cold‑weather real talk
Freezing temps, heater running, winter tires possible.
- Expect 20–30% less than EPA
- Plan conservative legs of 220–260 miles
Cold and fast are range killers
5 big factors that shrink or stretch EQS range
Dial in your EQS range in the real world
1. Highway speed
Above about 65 mph, air resistance rises sharply. The EQS’s slippery shape helps, but 80 mph will still eat into range compared with 70 mph. If you’re chasing maximum distance, slowing down 5–10 mph is the cheapest “upgrade” you can make.
2. Temperature & climate control
Cold batteries are less efficient, and heaters are hungry. Pre‑condition the car while plugged in, use seat and steering‑wheel heaters, and in extreme cold aim for shorter legs between charges.
3. Wheel and tire choice
Bigger wheels and stickier, wider tires look great but cost range. If you live in a cold or hilly area, choosing the smaller‑wheel EQS configuration on the used market can add noticeable range back to your daily drive.
4. Elevation changes & load
Climbing long grades can spike consumption. The EQS recaptures some energy on the way down through regen, but if you tow a small trailer or pack five adults and luggage, plan extra charging time in the mountains.
5. Battery age and health
A healthy 2022 EQS pack should still be close to its original range after a few years, but abuse and high mileage can take a toll. A professional battery‑health check, like the Recharged Score that’s bundled with every vehicle on <strong>Recharged</strong>, tells you how much usable capacity is really left.
How the 2022 EQS compares to Tesla and Lucid
In 2022, the range leaderboard was dominated by Tesla and Lucid. The Tesla Model S Long Range was rated around 405 miles, and the Lucid Air Dream Edition stretched all the way to the 500‑plus‑mile club. On pure EPA numbers, the EQS 450+’s 350 miles looks a step behind.
2022 Mercedes EQS 450+
- EPA: 350 miles
- Independent highway: ~395 miles
- Strength: Beats its rating, ultra‑quiet and comfortable
2022 Tesla Model S Long Range
- EPA: ~405 miles
- Independent tests often land below EPA
- Strength: Supercharger access, strong efficiency
2022 Lucid Air Dream
- EPA: up to 520 miles
- Independent tests support monster range
- Strength: Class‑leading distance, newer brand
Range isn’t the whole story
Charging speeds and road-trip pace
A long range number only helps if you can replenish that battery without losing half a day at a charger. The 2022 EQS can accept up to **200 kW on a DC fast charger** in ideal conditions, and Mercedes quoted a **10–80% charge in about 35 minutes** when the car was new. On AC power, a 240‑volt Level 2 charger at home will take a bit over 11 hours to go from 10–100%.
Realistic charging expectations for a healthy 2022 EQS
What to plan for on road trips and at home.
On a DC fast charger
- Peak rates up to ~200 kW in ideal conditions
- 10–80% in roughly 30–40 minutes when the pack is warm
- Plan 150–200 miles added in a typical 20–30 minute stop
At home on Level 2
- About 11–12 hours from 10–100% at 240 V
- Overnight charging easily covers most daily driving
- Smart charging can take advantage of off‑peak power rates
Road‑trip rhythm in an EQS
Shopping a used 2022 EQS: range & battery checks
The good news: early real‑world tests show the 2022 EQS starting from a strong position on range and efficiency. The question, shopping used, is how well the prior owner treated the battery, and how closely the car you’re considering still matches those numbers.
Used 2022 EQS range checklist
1. Confirm which EQS you’re looking at
An EQS 450+ and an AMG EQS feel similar inside but have very different range capabilities. Make sure the VIN and listing clearly identify the trim and wheel/tire package before you compare range tests or plan road trips.
2. Review real‑world efficiency logs
Ask for photos of the trip computer’s long‑term consumption and average range, or better yet, a recent full‑to‑low‑state‑of‑charge drive log. This gives you a sense of how the car behaves in the seller’s hands.
3. Get a professional battery health report
A battery‑health diagnostic looks deeper than a quick test drive can. At <strong>Recharged</strong>, every EQS we list includes a Recharged Score report that measures usable capacity, charging performance, and signs of abnormal degradation, so you’re not guessing about the heart of the car.
4. Check DC fast‑charging history
Frequent ultra‑fast DC charging isn’t automatically bad, but an EQS that lived on road trips and high‑power chargers may show slightly more wear than a commuter that charged mostly at home. Battery diagnostics help put helpful numbers behind that history.
5. Test a cold‑day drive if you can
If you live in a four‑season climate, try to test the car on a cooler day with the heater running. Watch how quickly the estimated range drops compared with miles driven; a healthy EQS should remain reasonably linear once the pack is warm.
6. Plan your own “mini range test”
After purchase, run your own controlled loop, say 100 miles at a steady 65–70 mph, starting around 80% state of charge. Note the efficiency in mi/kWh and how much charge you used. It’s a simple way to see how your real life compares with big‑name tests.
FAQ: 2022 Mercedes EQS range questions
Frequently asked questions about 2022 EQS range
Bottom line: is the 2022 EQS a true long‑range EV?
Taken together, the **2022 Mercedes EQS range tests** paint a picture that’s rare in the EV world: a luxury flagship that quietly *over‑delivers* on its official numbers. The EQS 450+ in particular is a legitimate long‑distance cruiser, with independent 70‑mph testing stretching to nearly 400 miles on a single charge, and the EQS 580 giving up surprisingly little range while adding all‑wheel drive and serious power.
If you’re hunting for a used luxury EV that can turn long days on the highway into something calm, quiet, and almost effortless, a well‑cared‑for 2022 EQS deserves a spot on your shortlist. Just make sure you understand which trim you’re buying, how the previous owner treated the battery, and how that specific car’s real‑world range lines up with your life. That’s exactly where a transparent, third‑party battery report, like the Recharged Score that comes standard with every vehicle on Recharged, turns a range estimate into real confidence.
