No. On the 8th Feb 2023 car was only 11 months old. Its now 23 months with just over 18000 miles on the clock.

The temperature’s rising, it’s nothing surprising…..

48.9/44.7

…we’re having a heat wave. 
 

You’re all tracking, right? It’s called physics.

Breaking 50?

49.3/45.8

…getting close

[Hayzee]

Mine is showing 54 with a/c but obviously not achieving that. I rarely use up the EV range each day which might explain my high estimate.

[AkioT]

Going to try something a bit different as far as tracking.. range is on the climb like most are reporting. Currently at 48/44.5 (started with 40/38 on delivery in dec) now reseting history every month to allow for more realistic performance against kWh and mpg. 
February in screen shot, every week has seen at least a 150m+ trip (non stop) twice a week, so challenging to absolutely influence mpg over this distance on the back of EV compensating. 
but… tracking at 65+mpg over 1.3k with miles per kWh climbing to 2.9. 
Should start to see 70mpg+ return and climbing over 3m per kWh

Real world though? I’m only putting in £35 of fuel each time for a 310ish mile trip. EV cost is literally at 80p over the 85miles I’m getting based on a charge both ways. I charge at home on the outbound (own cost) charge at office for the return (no cost, yes lucky I know..) 

I’m On an off peak tariff with British Gas and Hive at 9.5p per kWh alongside  a new beta incentive to allow the charge to be longer of the full off peak window to support low grid usage.. This reduces the tariff to 5p per kWh hence £0.80p for 48miles.  Incredible..!! 

So, at the moment it’s already running at 8.6p per Mile combined.. far cheaper than a hybrid and would absolutely wipe the floor with a similar sized diesel SUV.

I have a question.

As I understood, the Battery can't go < 30% so when it reaches that point the car switches to HV mode.

I charged the Battery to 100% and it showed 65 km (40 miles) of total range with an AVG consumption that in the meantime has reached 5.1 kW/h, I actually drove for that amount of predicted miles and now in car I see 3 notches of charge on the dashboard and from Lexus Link+ (which is a garbage app) I see 39% of residual charge with a predicted range of just 3.3 km (2 miles).

Is this correct or the car is underestimating the figure? I usually drive 10 km (6 miles) with 10% charge.

 

The way Lexus cars calculate the estimated range is still a mistery to me after years.

[Harrier Man]

My understanding is that, as you say, the traction Battery retains about 30% of its charge. There are good reasons for this but 30% does seem on the conservative side to me. I would prefer the app showed the percentage of usable charge; 100% when fully charged and 0% when there was no usable range left but it's not a big deal.

Same is true of the dash display; if I can't have/use the last 30%, then don't show it. True of the fuel tank too; if it's full to the top, I want to see all the bars in the green and for the number of bars to reduce proportionally until the tank is empty. Then I can be clear and know that if it gets to one remaining bar, I need to start looking for a petrol station. Toyota/Lexus conservatism is annoying here; as another thread has shown, owners have found that there is often still a significant amount of fuel left in reserve when the dash would have you believe that the car is in imminent danger of running out of fuel and being stranded.

Estimates on the dash display and the app cannot be calculated in the same way. My dash has been showing an EV range of between 71km and 73km for weeks now whereas the app has been gradually creeping up by 0.2 or so without a/c and 0.3 with a/c over the same period. However, to be honest, I just let the car get on with it; if the fuel looks low, I top it up, if the Battery needs charging, I charge it - a bit like the olden days before we had these fancy apps! I know that if I drive gently, I get more mpg or Battery miles, if I drive more aggressively my £ doesn't take me as far and I don't need an app (or a home smart meter) to tell me that.

And then again, what's the point of stating in the user manual that a full Battery charge (0-100%) will take 2 hours and a half at a constant peak charging power of 6.6 KW when it's clear that the car doesn't allow the Battery to be completely drained in the first place?

The actual Battery capacity we're allowed to use is 12.67 kW/h, therefore it would take less time to perform a full charge (30-100%).

With that said, yesterday I took the car and driving in the parking lot at very low speed decreased the range of 2 km, even driving in city only I've never been able to achieve the "89-98 km" of official EV range Lexus quote for city driving scenario, so at this point I don't care anymore and will just top the fuel/battery whenever I can.

Thank God I have a plug-in car and not a fully electric car, really, because I'd have sold it after 2 weeks because of the range anxiety.

It's always amazing to me how Toyota and Lexus seems to genuinely hate their customer base, between s*** like this and the app Lexus Link which has been horrible since the day they released it (literally open the app store on your phone and check the reviews under the app because 98% of them are insults and rants), I wonder how the entire world's journalists can still call Lexus a luxury brand, and I say this as a long time customer...

I believe that the reason the PHEV has a large 30% reserve for the traction Battery is because the PHEV has a total power output of 302 BHP created from the engine and an electric motor on each axle. When you floor the accelerator etc this demands full or nearly full power output, which means the traction Battery will be able to provide the necessary power to the motors even if you have zero EV miles available.

If you drive the car very hard with just the 30% reserve it is possible to see the reserve drop below 30% if the engine hasn't been able to maintain it because of driver demand. However, the car is clever enough not to let the driver deplete this reserve by too much by limiting BHP regardless of how heavy footed you are.

Mine too 53.3/52.2

Just looked back to my first 450h+ shown above (should read 9/5/2023) which at this time last year will have been 14 months old with approx 10k on clock.

In May 2022 there was another thread we were noting range on - I'll see if I can find any posts from then as my new car has some 'learning' to do !!

UPDATE:
I've found the other thread, titled: NX 450h+ electric and petrol range, but it seems like I was more interested in working out the mpg than a day to day electric range then!!

Actual today 33 with remaining range with A/C quoted as 11.4, so not too far off?

[Cicoria]

Lately I've been driving the car a lot in EV mode only, like some hundred miles, and the dashboards reads 5.9 kW/whatever is the unit although I've been able to reach almost 7 on some particular roads. This also driving very carefully and slow with a light foot, something that I wouldn't do in HV mode.

The 100% range is always 60-61 km or 37 miles without AC, I'm still unable to see the promised 70 km even with summer tires. Let's see if it gets better.

My September 2022 model is now up to 77km but this time last year it was around 70km, rising to 72km (peak of 73km) toward the end of summer. Car currently has 22,500km on the odometer. Seems it takes time for everything to get fully settled.

So, 6 months in now, just under 8k.. traction started at 38 now up to 55 as a full charge. Resetting monthly and now achieving 3.4mile per kWh. Lots of motorway driving so happy with this return. I anticipate that as we move towards warmer months now it’ll creep up towards late 50’s. Decent performance all round now. for May covered over 1200 miles, 750+ of which was in EV (61%)  As a result combined mpg for May: 101.7mpg.

Typical charge of up to 14.8kWh, on a decent off peak tariff (7.9p kWh) so costing £1.15 ish for a full charge.. also able to take advantage of a Hive smart charge offer which credits back half of the cost based on off peak grid availability. As such I’m charging at around 4p per kWh. Cheap motoring..!! Just over a 1p per mile on EV. 

All Reset for June now

I cant beat your efficiency. That's impressive numbers esquire. I am rocking 3.1 miles per KWh with mainly urban and A roads and a little motorway (hilly but with up and downhill so should theoretically even out id have thought). I do have an F-sport so don't know if that makes things worse. Real life I am getting early 50's now in electric so happy with that. My May stats are 450 miles with 79% EV and 243 MPG (most of my daily (return) trips are inside the electric range). Out of interest how do you use the car? Start in EV and let it run out? Manually switch between EV and HV or put it in auto and let it decide?

I am beating you on the charging front....got the Hive charger and years free charge offer. Just hope the smart charge is still about when I come off it!

[AkioT]

Hi, also in an F-Sport, ran a 450h+ premium before this and the performance was marked (much improved) due to smaller wheels, less weight etc.. that one managed to capture a charge/range of 65 and i’d regularly get late 50’s to early 60’’s.. incredible really. However the F-Sport looks great so I’m sure i’ll manage😉.. As far as driving then I always kick off in EV and let it run out then over to HV. I genuinely can’t work out if there’s any really difference in selecting auto EV/HV as in most cases I’m setting off to distance etc. 

Because it’s just so cheap to charge I always select EV, no brainer.. 1.5p per mile versus 12p per on HV. Hence use the EV first.. 

Excellent that you have a years worth of free EV..!! That’s fantastic. I’m year 3 with my hive box and no issues to Speak of. Home charge for me always.. 

We’re also running a Toyota bZ (Fwd) and that doing really well.. tend to get 240ish mile per charge and it’s running at 3.9kWh which is excellent tbh. Just urban though and the odd trip. It’s so accurate that we’re only charging it once a month. It believe it or not that costs about £2.60..!!  Honestly… can’t make it up can you?

June stats

EV 51

EV with ac not listed with this charge.

not convinced I get this on a long run but will check  mileage against EV use. 

[Pm4]

When I check the charge on the app, it's always an higher reading than what it shows in the car, by 2/3 miles. Why is that and where does the app gets the information from ?

The car uploads the info to the Lexus servers where the app obtains it's data. My app info is more or less the same as in the car.

[Pm4]

I realise that Lexus quoted figures are not too reliable but just out of curiosity , when I bought my 450h they advertised around 50 miles electric range but now they advertise around 40 miles ? Same car so why?
