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?

Maybe more realistic? They get all our stats so perhaps Lexus  have been able to refine their claim based on UK Real World data for summer and winter?

July stats 

EV range 52.8

EV A/C.    52.2

[Delboy wilts]

August stats

EV range 53.5ml

EV/AC.     52.4ml

[AkioT]

July figures:

1406 miles covered. 

Achieved combined 83.7mpg

3.6m per kWh

Now up to 58.1 on full charge, achieving early 50’s in full EV 

At home charged: 139kWh over the month. 

cost: £5.89 (4p per kWh, off peak) so essentially that generated 450-500ish EV miles (not including HEV) 

On average a gallon in fuel is around £6.40? You’d get what? 40ish miles in a conventional car? 

 No comparison is it… (understatement…)

Are you using Octopus Agile to achieve that rate?

[AkioT]

No, British Gas Ev driver tariff but its linked to a hive beta smart charge offer, essentially if you enable “smart charge” you  allow the grid usage to determine how long to charge based on peaks (even though it’s 12am-5am) once you’ve fully charged up they then credit back around half of your charge.. just plug and walk away.. nothing else to do..

in the 3 months I’ve been opted in it only ever takes about 2hrs 20mins to charge at a rate of 14.2kWh as average and the credits always land post decoupling 

Great offer tbh..

Where did you get this figure?

I’ve done 1426 miles since I got mine, inc one trip of 250 miles.  My average mpg is 122mpg and my range has risen from 40 to 49 miles so far in just under 2 months

Morning,

It’s a combination of using Lexus Link+ and actually resetting performance in the car on the 1st of every month then monitoring. Each and every journey polls and match from both app to car. 
I used to just leave it but I’m interested in seeing the impact of seasonal changes now.. 
just to check is it the mpg/range or the charging data your referring too? 
 

thanks

[rdc]

It was was the Kilowatts charged I was wondering about 👍

[AkioT]

Ahh.. ok… yep, the kWh is reporting from my Hive App, it’s directly linked to my wall box and captures all kWh pulled Down. Pretty straightforward but also summarises monthly’s and ytd inc £‘s and averages etc..

Did a check of  milage against predicted

Milage 44 EV 52

            23/27 

appears to be a 20% difference

51.9 is my highest ever in over a year since new. What am I doing wrong? 😁

[Harrier Man]

I thought/hoped that in my second year of ownership I would see an improvement to the predicted range but I haven't. Last year, I achieved a best of 51.1 and 50.6 without and with A/C respectively. This year the best predicted range without A/C was 50.9 and with A/C was 49.9

The difference is probably too small to be statistically significant but I wondered how others had fared?

[GMB]

50mpg ain't bad. The worst I ever got was 9mpg thrashing my Audi 200T. Normally 14mpg at modest speeds. Mind you petrol was  less than £1 per gallon in 1981.  ( 22 pence per litre )

[AkioT]

Over 2 NX’s I’ve seen a Premier spec (not Prem Plus) top out at 66, without AC (and once achieved 64 of that.. with a tail wind) then now my current FSport topping out at 59 but difficult to get anywhere near 50..

Both a Premier Plus spec and FSport have the wider larger wheel with a  lower profile, so that has no immediate impact and usually with a heavy sunroof.. hence the combination of a Heavy car with greater resistance. Doesn’t sound like it’d make too much difference on paper but it does.. 

The other aspect is that the predicted range is based upon the last accum 10 journeys and is forever rolling. If your daily use mainly consists of higher speeds it’ll predict based upon that without the balanced opportunity to capture urban with natural regen in traffic opportunities. 
tbh, if you predict 50 and get mid 40’s from a charge or 14.3kWh (real world 13.5kWh) then that’s a great place to be and most likely translates to around 3.3m kWh which for a heavy awd car is excellent.. 

However…. If we all lived in a country with an all year round balmy temp that never got any higher than 25 but never lower than 16 then we’d all be getting very different numbers…
