If you’re looking at a 2025 Lexus RZ, you’ve probably heard two very different stories about range. On paper, the RZ 300e and 450e post decent EPA numbers. In real‑world range tests, though, the RZ often comes up short of its rivals, and sometimes short of its own window‑sticker promises. This guide walks through every major 2025 Lexus RZ range test we have, so you know what to realistically expect on your daily commute, highway trips, and in cold weather.
Two versions, two very different range stories
2025 Lexus RZ range overview
2025 Lexus RZ range at a glance
On the spec sheet, the 2025 Lexus RZ looks competitive for a midsize luxury EV SUV. The RZ 300e is rated up to 266 miles of EPA range on its standard 18‑inch wheels, while the RZ 450e tops out at 220 miles with 18‑inch wheels and 196 miles on 20‑inch wheels. In practice, range depends heavily on wheel size, highway speeds, weather, and how gently you drive. Independent testing suggests you can beat the EPA in mild conditions, but winter and high‑speed driving take a bigger toll on the RZ than on some rivals.
Wheel size matters more than you think
EPA range ratings for 2025 Lexus RZ 300e and 450e
Official 2025 Lexus RZ EPA range and efficiency
How the 2025 RZ 300e and 450e stack up on the EPA cycle by wheel size.
| Model / Wheels | EPA Range (mi) | City MPGe | Highway MPGe | Combined MPGe |
|---|---|---|---|---|
| RZ 300e FWD – 18" | 266 | 137 | 112 | 125 |
| RZ 300e FWD – 20" | 224 | 114 | 96 | 105 |
| RZ 450e AWD – 18" | 220 | 115 | 98 | 107 |
| RZ 450e AWD – 20" | 196 | 102 | 87 | 95 |
EPA range ratings are useful for comparison, but real‑world driving will vary.
EPA numbers for the 2025 RZ tell a clear story. The 300e is the efficiency champ: a larger CATL‑supplied pack and single front motor help it stretch to 266 miles with excellent MPGe. Step up to 20‑inch wheels and you lose roughly 40 miles of range. The 450e, with its dual‑motor all‑wheel drive and slightly smaller usable battery, trails by about 40–50 miles across the board and is notably less efficient on 20‑inch wheels.

Real-world range tests: what independent data shows
Key 2025 Lexus RZ range test results
How the RZ has performed outside the EPA lab
Edmunds EV Range Test
RZ 450e (20" wheels): 204 miles measured vs. 196‑mile EPA rating.
RZ 300e (20" wheels): 245 miles vs. a 224‑mile EPA rating.
Both trims modestly exceeded their EPA ranges on Edmunds’ mixed real‑world loop.
Car and Driver 75‑mph highway test
Earlier testing of an RZ 450e on 20‑inch wheels yielded just 120 miles of range at a constant 75 mph, far below the EPA figure.
That underscores how sensitive the RZ is to sustained highway speeds and big wheels.
UK winter range test
In a 2024 winter comparison in Europe, a high‑spec RZ with 20‑inch wheels managed only 159 miles before stopping, well below its WLTP rating.
The RZ was one of the weakest performers in that cold‑weather group.
Put those tests together and a pattern emerges. In mild weather and mixed driving, a 2025 RZ can slightly beat its EPA number, especially the 300e, which delivered 245 miles in Edmunds’ testing on the less‑efficient 20‑inch wheels. But in steady 70–75 mph highway driving, range shrinks quickly. Earlier testing of the all‑wheel‑drive RZ suggested only about 120 miles at 75 mph on big wheels, which is far below the EPA highway rating. Throw cold temperatures into the mix and the RZ’s usable range shrinks further, with one winter test showing just 159 miles before shutdown.
Why some RZ tests look so bad
Highway vs city range: how the RZ really performs
City & suburban driving
In stop‑and‑go or suburban traffic, the 2025 Lexus RZ leans on regenerative braking to recover energy. That’s where its EPA city MPGe ratings, up to 137 MPGe for the 300e, translate into solid real‑world results.
- Short trips and lower speeds favor the RZ’s efficiency.
- Owners report getting close to EPA city range in mild weather.
- Using Eco mode and lighter acceleration can add 10–20 miles to your displayed range.
Highway and long‑distance driving
At U.S. freeway speeds, the RZ’s bluff SUV profile and modest battery capacity become more obvious. Independent tests have shown its highway range dropping 30–40% below EPA ratings, especially with 20‑inch wheels.
- Plan on 150–180 miles between DC fast‑charge stops in an RZ 450e.
- The 300e does better but still trails many competitors.
- If you routinely drive 75–80 mph, build in a wide buffer.
Highway planning rule of thumb
Winter range testing: why cold weather hurts the RZ
Every EV loses range in the cold, but the RZ’s winter numbers stand out. In a 2024 comparison test, a top‑trim RZ on 20‑inch wheels managed just 159 miles before it shut down on a controlled winter loop, significantly under its official WLTP rating and behind many competitors tested the same day. Even in less extreme scenarios, owners and testers see roughly 30–40% drops in range once temperatures fall near or below freezing, particularly on short trips where the battery and cabin never fully warm up.
- Heating the cabin and battery consumes a bigger share of the RZ’s modest usable capacity than in larger‑pack rivals.
- Short winter trips are especially punishing because you repeatedly pay the energy cost to warm things up.
- Thicker winter tires and cold‑stiffened lubricants add rolling resistance, further shaving range.
- On 20‑inch wheels, the RZ is already working harder aerodynamically and mechanically. Cold weather magnifies that penalty.

Charging speeds and how they affect usable range
Range isn’t just about how far you can go on a single charge; it’s also about how quickly you can recover miles on a road trip. The 2025 RZ line uses DC fast charging up to about 150 kW and comes with a relatively modest onboard AC charger, 6.6 kW for earlier 300e/450e models, with Lexus moving toward an 11‑kW unit on newer variants. This is mid‑pack in today’s EV market: not painfully slow, but a step behind the quickest‑charging luxury SUVs.
2025 Lexus RZ charging basics
Approximate charging times and real‑world takeaways for the RZ 300e and 450e.
| Scenario | Approx. Time | Miles Added (RZ 300e) | Miles Added (RZ 450e) |
|---|---|---|---|
| DC fast charge 10–80% | ~30 min in ideal conditions | ~150–170 | ~120–140 |
| DC fast boost (10 min) | ~10 min | ~50–60 | ~40–50 |
| Home Level 2 (240V, 6.6 kW) 0–100% | ~10–11 hours | Full pack | Full pack |
| Typical overnight top‑up (40–60% to 80%) | 3–5 hours | Enough for daily commuting | Enough for daily commuting |
Numbers are approximate and assume normal conditions; cold weather or crowded chargers can increase times.
Good enough for most, but not class‑leading
How the 2025 Lexus RZ compares to rival EV SUVs
Range is where the 2025 RZ looks most vulnerable against its competitive set. Many similarly priced luxury EV SUVs offer more usable highway and winter range thanks to larger batteries and slipperier shapes. The Lexus counters with a lower starting price for 2025 and a familiar, comfortable Lexus driving experience, but pure range shoppers have better options.

Where the RZ still makes sense
Range tips for Lexus RZ owners
Practical ways to stretch your 2025 Lexus RZ range
1. Choose 18‑inch wheels if possible
If you’re still spec’ing a new RZ, or shopping used, prioritize trims with 18‑inch wheels. They deliver noticeably better range and smoother ride quality, with less aerodynamic and rolling‑resistance penalty than the 20‑inch setup.
2. Use Eco drive mode around town
Eco mode tames throttle response and optimizes climate settings. In everyday driving, that small change in behavior can add 10–20 miles of practical range, especially in the more efficient RZ 300e.
3. Precondition while plugged in
On cold days, use cabin preconditioning from the app or in‑car settings while the RZ is still plugged into Level 2 or DC fast charging. You’ll warm the cabin using grid power instead of draining the battery on the road.
4. Keep highway speeds realistic
Above 70 mph, aerodynamic drag climbs fast and the RZ’s efficiency falls off. Holding closer to 65–70 mph instead of 75–80 can be the difference between making the next charger comfortably or stressing over the last few miles.
5. Plan conservative winter legs
In freezing weather, assume you’ll see 30–40% less range than EPA. Build your DC fast‑charging plan around that reduced figure and avoid arriving with single‑digit state of charge if chargers are far apart.
6. Watch the energy screen, not just the guess‑o‑meter
Use the RZ’s energy consumption display to track kWh/100 miles or miles/kWh over longer trips. That’s more reliable than a constantly changing predicted range readout and helps you adjust your driving in real time.
Used Lexus RZ: what range shoppers should expect
Because the RZ launched for the 2023 model year, 2023–2025 examples are already entering the used market. That’s an opportunity if you understand the range realities going in. Lexus projects relatively modest battery degradation over time, and most early RZs are still under their original battery warranty window. The bigger swing factor for a used buyer is spec and use case: wheel size, drivetrain, climate, and whether the previous owner frequently fast‑charged or drove lots of highway miles.
How Recharged helps you shop range‑sensitive used EVs
- Expect a healthy used RZ 300e with 18‑inch wheels to still deliver well over 200 miles in mild weather mixed driving.
- An RZ 450e on 20‑inch wheels used mostly for highway commuting may show more noticeable real‑world range limitations, even with a strong battery.
- Battery degradation is rarely the main story in the first 5–7 years; driving pattern and wheels matter more to day‑to‑day range.
- If you’re shopping used in a cold‑weather state, ask specifically about winter range experience and charging habits.
2025 Lexus RZ range FAQ
Frequently asked questions about 2025 Lexus RZ range
Bottom line: is the 2025 Lexus RZ’s range enough?
The 2025 Lexus RZ doesn’t win the range test on paper or in many independent real‑world comparisons. The RZ 300e delivers respectable numbers if you stick with 18‑inch wheels and mostly suburban driving, while the 450e trades too much range for its extra performance when measured against newer rivals. Highway and winter tests show that the RZ is especially sensitive to high speeds, cold temperatures, and big wheels, so it rewards thoughtful spec choices and realistic expectations.
If your priority is a quiet, comfortable luxury EV for daily use with reliable home charging, the RZ can still be a smart fit, especially as prices ease and lightly used examples hit the market. If you’re shopping used, that’s where Recharged comes in: our Recharged Score Report verifies battery health, range, and pricing so you understand exactly what you’re getting. Combine that with EV‑specialist guidance, financing, trade‑in options, and nationwide delivery, and you can decide with confidence whether a Lexus RZ, or a longer‑range alternative, makes the most sense for how you actually drive.
