This rage is terrible and I am always scared I will be low and have no where to charge. I have to constantly stop and charge with fear of running out as it does not give you an estimate of your percentage upon arrival of your destination. Where as my Prologue provides estimate percentage for arrival and round trip and is very accurate.

 

 

What model do you have?
Was it parked outside in freezing temps overnight?
Once the battery warms up, the range will increase back towards whatever you normally see!

With more EV miles under your belt, you will grow out of this fear.
We charge ours (RZ, Model 3) once per week, mostly at home or at work (where it's free).
Then again, this is my 5th EV, and I do faintly recall range anxiety when we got our first a decade or so ago. It didn't take long to subside.

Toyota software leaves a LOT to be desired, including a lack of EV-centric integration in mapping/rout-planning. Their hardware is rock solid, but the software is borderline crap.
What I've found is that I get 3.3-3.6 miles per KWh. The battery is 72.8 KWh, so 72.8 * 3.5 == 240-260 miles under ideal circumstances.
Consequently, 1% of battery charge is 2.4-2.6 miles.

I have the Lux package - 21" wheels and I manage 3.2 miles per kwh

Like the OP, I"ve noticed my range increasing or decreasing, tracking with the outside temp.

I know where and when I'm driving (for the most part), so I know in advance if there's going to be a range issue, so no anxieties here.

 

I'm 4,000 miles in on my 450e.

nowhere to charge I can't help you with. these definitely favor easy access to level 2 garage charging.

OK, so first off, if you have the 20" wheels, you're sort of screwed. The final drive ratio on these is too high for 20s (and for speeds above 60mph). But if you have 18s and do mostly urban and suburban driving...

1) always use max regen braking when not on highway, learn to brake with it
2) set drive mode to custom, choose sport steering, eco hvac. whether you choose sport or normal or evo for motor depends on how much of a leadfoot you are

if temps are above 40F and you aren't using hvac, this should get you about 4.3m/kWh and 260 miles of range. if you have to use hvac, this will be more like 220-240. if temps are freezing and you have to use hvac, you're looking at more like 200 miles of range, maybe less depending on how cold it is.

also, it's not the most fun to drive, but range mode basically prioritizes all torque to the rear lower wattage motor. you can get 270-290 in range mode with a 450e and hvac off in non freezing temps. I can confirm 273. I have not driven all the way down to confirm 290.

 

This is a bit misleading:

• 18" wheels wear 235/60R18 tires (front) for the overall rolling diameter of 29.10".
• 20" wheels wear 235/50R20 tires (front) for the overall rolling diameter of 29.25", or 0.51% difference.
• 20" wheels wear 255/45R20 tires (rear) for the overall rolling diameter of 29.04", or -0.23% difference.

For all practical purposes, their overall diameter is the same, and thus there is zero practical difference in the final dirve ratio.
The difference in range from larger wheels comes from the introduction of wider (255mm vs. 235mm) tire sizes and grippier summer tire rubber on those wheels, not the wheel diameter.

I agree on #1, and for #2 you can tweak things as you please.
I've never seen the rated 266mile range on our RZ300e, even under ideal temps and conditions in mid-fall.

Based on my prior EV experiences:

• Driving on a highway will impose 15-25% range penalty, depending on how fast you go.
• Driving in near freezing (<40F) temps will impose 10-25% range penalty, depending on how cold things get. Below 10F, the range penalty goes exponential, as battery energy will be expanded to heat the battery itself regardless of what you do with HVAC.
• Driving over snow/slush will impose ~10% range penalty.

Ah, thought there was more added diameter/circumference with the 20". And a bit weird because the width difference only seems to be with comparing front tires--rears end up being nearly identical with tires. The front higher wattage motor really dislikes the bigger setup. Also stinks because the 20s eat into quickness, too.

re: range, in the UK, the RZ300es are rated for nearly 300 miles and the RZ450es around 270 miles: https://www.lexus.co.uk/new-cars/rz

I assume they are putting the 450e into range mode to achieve that. Does the 300e have range mode without the second motor?

 

Hi all,

I’m new to the 2023 RZ450e Premium and recently took it on a long trip after fully charging it for the first time. Initially, the range displayed with HVAC on was 200 miles. My destination was only 100 miles away, but by the time I arrived, the battery was down to 10%, suggesting a real-world range of around 120 miles.

Is this normal behavior for the RZ450e, or could there be an issue with the battery? I’d appreciate any insights or advice.

Thanks

 

As I mentioned above, range very much depends on how you drive, where you drive, in what temps you drive, and how fast you drive.
If you were cruising at 80mph in Main in freezing slush/snow, then yeah, 120 real world winter highway miles might be the limit.
On the other hand, if you were doing 50mph on back roads in Arizona in 68F weather, then you might see 250+ miles.

So the way I understand it best results in Range Mode are with 18” tires, max Regeneration Braking, and warm weather. Let’s say you’ charge to 90%,
the range is showing 200 miles on the dash or the app and you record your odometer reading. Then say you drive say 50 miles now the percentage should be 45%. if it’s significantly higher than that then the Range Mode is working.

 

Kinda.
Not strictly 18" tires, but low-resistance All Season tires that are suboptimal for grip, handling and safety, but better low rolling resistance and range.
Then you want to drive like a grandma : slowly ( <55mph) and gently.

% of estimate mileage (or battery) remaining should work the same way it has always worked in ICE cars - you extrapolate recent energy consumption for the remainder of energy available in gas tank (or battery).
If energy estimation works corrrectly, starting with 200 miles and 90% SOC (State Of Charge) should drop to 150 miles and (200-50)/200*90% = 67.5% SOC.

The estimate should be adjusted based of whatever driving mode you chose, so as long as you stay in the same mode, the range / SOC estimate should be close to actual.

My 300e with 18 wheels, shows a lifetime average of 4.5 miles/kWh over 2200 miles. I am getting about 280- 300 miles per charge.
MOST of my driving is in the city and mild winter weather in Georgia.

 

My 2017 RX350 is doing fine, knock wood, but I am interested in its eventual replacement. I'd never buy the V-4. Have there been any reports or well-founded rumors about the range of future RZ's?

 

EV's love congested stop/start driving; uses little energy!
However, a lot of energy is required for hi speed cruising, esp with air conditioning on, and moreso under extreme temperatures.
The RZ is dying for a bigger battery pack.
Just that Panasonic took off with Tesla, hence not much Lion left for TMC.
The Chinese and Koreans supply themselves.
A breakthrough in alternative battery chemistries would really tip the scales...

 

RZ300e has a 72.8 kWh LFP battery pack (optimistically) rated for 266 miles, or 3.65 miles per kWh. RZ450e is worse.
My Tesla Model 3 AWD has 75 kWh battery rated for 353 miles, or 4.71 miles per kWh. That difference represents 29% more efficient utilization of energy by Tesla vs. Toyota.

Toyota really needs to up its game in EV motor efficiency first and foremost.
Everything else about the RZ line is fine - design, handling, interior, options, quality.
But the EV drivetrain is sadly not up to par with either what Tesla or BYD had developed and started selling 4-6 years ago.

There is no evidence for this conspiracy theory.
Toyota is using Panasonic batteries in 450e, and cheaper CATL (Chinese) LFP batteries in 300e. They could get more of either type if they so desired or needed.

There is a global market for EV battery production, with numerous suppliers and buyers across many continents.
Toyota buys batteries from Panasonic, CATL, and others.
Tesla buys batteries from Panasonic, CATL, LG, and struggles to manufacture thier own.
Tesla will likely get negatively affected by the idiotic taxes on trade (aka tarrifs) that are about to knee-cap the US manufacturing. Toyota's supply chain will remain unmolested - Japanese government is not stupid.

Unnecesary, however welcome.
Toyota just needs to do a better job engineering their EV powertrains. Larger battery packs can mask this problem, but only marginally.
Time will tell how much they manage to up their game, but it's unlikely to happen overnight.
