I am really glad we don’t get real low / well below freezing temperatures - this article reports the real effect on a Tesla Long Range - https://www.hotcars.com/how-winter-weather-shortens-range-tesla-model-3/

List price on any ‘prestige’ EV is a definite no no. I’ll repeat though that I’m not as depressed as I might have been as I got a ridiculous px for my Velar. If I’d kept the Velar I would have lost about the same as the RZ has melted ! I was offered a factory ordered RX450h £ 15k below list so it’s not only EV’s apparently. with EV’s I think you need to be clear about what you really need. Range and charging but nothing else, Tesla are unbeatable, reliability and good range the Koreans, comfort, well finished but mediocre range Lexus, old battery tech and mediocre and misleading range the Germans. I see loads of articles about charging and a lot of them are totally misleading. Doing down a car with 150kw capacity against say 250kw really only means about 10 mins for 20% to 80% and is that a big deal for occasional public charging. Maybe for a road warrior and thus a Tesla but a concern for a luxury SUV, probably not. I think that Lexus US provides proof of the market for the RZ - they provide an ICE car of choice free for 30 days over 3 years for road trips, shame they didn’t provide it here.

Kevin. Thorough test but pre-update - check the dash. John & I have been getting far far better figures. What Car are a very reputable testing house but for some reason they and most other tests result in far worse figures than those actually experienced. You’ll see from earlier posts that post-update 200+ real miles are easily achievable and efficiency upwards of 2.9 miles / kw. Comparing a BYD with a Lexus is like comparing a Dacia with a Lexus ! Look at the difference in claimed efficiency and actual at the end of the video and you’ll see even pre-update Lexus’s actual is better than claimed. I totally agree with John that the RZ was marketed far too early - they have totally blundered as all the reviews are for cars pre-update and the car shouldn’t have been released without it. Now the drop for heating is significantly less and use of the radiant heaters means ‘UK winter running’ is not an issue. Do I regret buying the RZ - yes. Am I happier since the update - far happier. With what has happened to EV residuals, would have I been happier with a different EV - no ! Lexus will be in a very difficult place this year as they have to achieve 20% of all sales being full EV, every car sold below that accrues a £ 15k fine - one of the main reasons in the drop in RV’s is manufacturers will reduce prices to sell rather than pay a fine to achieve nothing. There is no hope of Lexus getting anywhere near 20%. We have been totally misled by the government into buying EV’s as they then changed the rules by removing the 2030 ban at the same time as levying fines - total idiocy

Any decent dealer would install it prior to sale. You can easily tell by the battery state having a % in the display - pre-update this was not available. I am sure the update isn’t a recall as it isn’t a safety issue.

Look at the other thread on here and see the actual miles achieved by owners, rather than critics. Particularly look at the range change after the update - they are significantly more than 2.4 and the review was possibly a pre-update car.

In the RZ App you can set a stater and stop time - you set the start and then the turn off time. In the car you can set the maximum charge %

I had a problem with Siri in messages in CarPlay. After dictating a text Siri would only read back the first word ! Consequently, sending a text I had no way of knowing whether Siri had compiled it correctly. Did a lot of research and concluded it was caused by IOS 17 - I updated to IOS Development Beta and problem solved. Maybe that is your issue.

SamHe after the update in my car if the a/c or heater fan is turned up to 3 (eco comes up) the loss in range is less than 10 miles but over 20 miles if put on faster. Today I repeated my last charge using a 350kw charger and was getting 32kw at 86% which is far higher than the charging curve I have based on the pre-update - it says only 8kw could be achieved.

John. Had a trouble free drive. Stopped at Rugby Moto Services - loads of rapid chargers available. The 20 Tesla ones are now live too so helps. Was even getting 20kw at 91%. I averaged 3.2 m/kw driving at 65mph the whole way. Now using a 75kw rapid at 40% and getting the charger max so happy with that.(The 25 in the shot is the speed of the CA charger not the CCS) I noticed that the range drops marginally (about 7 miles) if the aircon / heating is up to 3 then 25 miles if on full. Again, very happy with that. I asked and they did update the map to what looks to be Dec 23. The traffic cameras are shown much better. See the screenshots for your discussions when you take your car in for the DC work.

Last summer, I had to use public chargers for 6 weeks and in those temperatures on 150kw chargers it was taking about 30 mins from 20% to 80% so ok. I have a longish drive next week so expecting it to take longer - I hope it does better than 40 mins for 50% but not expecting it. We’re taking the car to Jersey in August - from what I can see they have only 2 ultra rapid chargers on the whole island, vast majority of chargers are 7kw so that will be a ‘challenge’. I think it is an indicator of what could happen here - they don’t have the infrastructure and power generation to allow loads of ultra chargers, which explains why there is not the even spread of chargers here.

Glad to see the owner membership growing - I think up to 4 of us now ! I believe the update increases the range by reducing the buffer with some other software improvements including reducing the dramatic indicated loss in range for using the aircon / heating. When was your car manufactured ? The cars built late 2023 had the update installed at he factory - that may be why you seem to be achieving 3.0 miles / kw ! I think it is a fault with the design but maybe it’s just my car - can you have the fan on without the a/c and so the indicated range doesn’t dive ? In my case, having the a/c button on r off doesn’t make a difference. Pleased to see a favourable review by someone who has driven the car for more than 30 minutes or read American reviews. I posted an extract from Car Magazine which you may find of interest to quote when the Tesla fans deride the RZ for lack of range - https://www.lexusownersclub.co.uk/forum/topic/145762-diminishing-range-on-a-full-charge-and-slow-charging-rates/?&page=2#comments

I came across a very detailed review and comparison in Car Magazine. A UK magazine so without the American bias. I found it very interesting seeing the ‘official ranges’ versus their actual test ranges. They tested in fairly cold conditions with heating on at reasonably fast driving. The Polestar particularly, makes the RZ (especially after the upgrade) look a much better option

Luckily I haven’t had any probs with the charging cover. My car was delivered last May. I’ll ask if they can provide my locking wheel nuts next week. Somehow I managed to bend the ‘Lexus’ scuff plate on the drivers door cill. Did some research and found a supplier of genuine Lexus parts - if you ever need any parts or accessories give them a try, the service has been fantastic and you know it is the correct part as they use the VIN to ensure it is and it comes in Lexus boxes - https://lexuspartsdirect.co.uk Must be well cheaper than through a dealer.

Mine is in for the update next Tuesday - the dealer offered to collect or I can go to them and have a curtesy car. I suspect it was this that pushed the booking until next week. I’ll be really interested to see if both of you report a real increase in range and particularly a great increase with the heating on.

John. Another screenshot for your dealer to see.

John. My average is 2.9 miles / kw over 6k with about 60% at 70+ on dual carriageways and some air on / heat

John. I am sure there is something amiss with your charging / battery. If it’ll help, I’ll keep a log so you can show Lexus your car is not providing the range it should. I shouldn’t, but on our local dual carriageways (about half my journeys) I drive at 70(+) preheat and then only have heat on for demisting. I have set the auto seat heating at +2 and find that with the auto radiant warm enough - luckily no back seat passengers or drivers. The Cross Climate 2 tyres haven’t seemed to effect the range - they certainly feel to provide a lot more grip.

Standby for the Tesla fans …….

During the very cold spell and a fair bit of dual carriageway driving mine is showing about 195 to 200. Screen shot - 186 at 95% so about 196 at 100%. The miles driven was 10 so again 196. The temperature drop effects all EV’s - some by as much as 35%

The Autotrader 63 includes new upcars not resales

I order CC2’s today and being fitted before Friday. The RZ has 255x45x20” rears and 235x50x20 fronts. I ordered using a local tyre dealer I have used for years - if you find the size you want on the Michelin site it takes you to Blackcircles that then offers local tyre fitters. Good price too as they are giving 10% off with the code Jan10. https://www.michelin.co.uk/auto/tyres/michelin-crossclimate-2

rayaans- Where did you learn of CanBus thefts and Lexus providing the plates ? Why would a normal owner of a Lexus be aware of a post manufacture fitting of a security measure, other than by a recall. Keyless thefts have been all over the media for years and manufacturers have changed key devices etc as did Lexus. It’s because Keyless became more secure the thieves found and exploited the CanBus vulnerability. Newspapers and other media explained how keyless theft works and how to overcome it. In all the articles I have read about Lexus having the 2nd highest theft rate, none of them mentioned CanBus attacks so normal owners assume it is Keyless. Other than on these type of forums / websites no media has broadcast or informed about CanBus thefts. Lexus aren’t going to, as that just attracts even more thefts. I think it is wrong to suggest that the owner is in any way responsible for a theft because they didn’t have a little known post manufacturing device fitted - that is a small step away from saying insurers shouldn’t pay out if an owner hasn’t taken every single measure to prevent a theft.

My calculations showed with electric at 28p / kw the RX450h+ costs about 11p / mile for the 35 miles range against petrol about 19p / mile. I quoted my Range Rover at overall 90 mpg for 12,000 miles so the saving was considerable !

Tom - good to hear, I’ll try that. The beeps when locking the car seem to be random. At first I thought it was the second press causing it - reminding you that the internal sensor was armed so not to be used if a pet or child was still in it. There just doesn’t seem to be any logic to it - sometimes it’s total silence and then for no reason the beeps happen on the next locking. The second press just double locks, apparently the intrusion and tip sensors are armed after just the single lock. As usual, the manual doesn’t seem to cover it at all.

John. I do wonder if the rectification of the charging unit has helped. I never drive to preserve range - drive just as I would a petrol except not having the heating or ac on full blast maybe. My charging app is brilliant at providing data and with the trips in the Lexus Link & my tracker I can accurately see my true range and consumption.
