I’m a few weeks into ownership and at 50% of my first tank of petrol having traveled 598 miles. I estimate 80% of this was in hybrid mode not EV. I decided to let it do its thing.

So far I’m pleasantly surprised how the 440e is working out, this is the family/dog car and will do about 1k miles a month of relatively short trips.

The hybrid mode is pretty smart and seems to balance the power sources well, the few longer runs have achieved over 100mpg. What I would say is it’s better if you use the Land Rover sat nav, it then plans energy use for the journey. I compared the same 40mile journey with LR and CarPlay nav and the MPG was 30 less with Car Play.

It won’t be good for everyone and depends on infrastructure available but I think it was the right choice for my use case. MY23 PHEV HSE

Interesting, thanks RDR. I've just completed 1500miles in one month of taking delivery of my p440e HSE. The overall MPG is showing 65mpg so far. That's with around 700 miles in hybrid, the rest shorter journeys in full EV mode. On a long run of 200miles in hybrid its showed 41.5mpg using the JLR sat nav to plan use of the battery which I think is pretty good considering its a fair old lump. I found the battery drained around the 150-175miles mark if I recall and it was on full petrol by then with just mild hybrid retained for slow starts

Of course the mpg figures are misleading as you are still paying for the electricity and this is not taken into account in the MPG figures.

The EV range seems to have settled to about 53 miles real world and I expect this to climb as the weather gets warmer.

Very pleased with it so far and it definitely suits my car use patterns really well (40 mile daily commute in full EV, monthly or so long journeys in hybrid).

Just wondering, do you plug the car in every night to keep the batteries fully charged, and is that via a domestic 13A socket or via a dedicated charging unit ?
Is it OK to charge it in a garage, or is it safer done outdoors?

The overall p/mile would be a more interesting comparison, as Yousif says, mpg figures are very misleading, especially if you don’t do a lot of longer journeys. MY23 Panamera E-Hybrid

Mpg is misleading, I’m staying away from raising overall cost as it’s a can of worms. I’m really lucky to be able to charge from solar or cheap rate. Having owned BEVS since 2014 and still do as a commute car I know personal use case is critical to weighing up options.

I treat the car like my mobile phone and plug it in at night on the drive. MY23 PHEV HSE

Swings and roundabouts depending on whether you have charge and the length and speed of your journeys. Here’s three sections of a road trip I did coming home from the alps at the weekend in the P440e (see pics).

First part of the journey I had zero charge but the regen gave me a few miles from downhill sections.

The second and third parts of the journey were after a charge at the Novatel in Tours.

The best I was getting out of my D300 on 50 mile plus journeys was 42mpg.

As others have said, it really depends on how you use the car. The commute to work is all electric for me but longer journeys will only be efficient if you have charge.

See that Harry Metcalfe cancelled his partly because of poor efficiency in EV mode - looking at the official figures, m/kWh is poor but not miles away from other big, heavy stuff.

I’m looking forward to the longer journeys to enjoy the car but know it won’t be as efficient as diesel unless I charge. I won’t let charging impact a holidays I’ll just suck up the inefficiency 3 or 4 times a year.

One other pleasant surprise I have used the sheffield green car parking scheme for years with my BEVS and it let me register the Range Rover too so I can park in council car parks and on street for free. MY23 PHEV HSE

I have had two p440e and Harrys review on efficiency has made me think twice. There are still huge benefits in relation to emissions etc. These are not my calculations, they were in a tweet after the review was posted.

Great review as ever. My semi ignorant thoughts on costs: 33p/kwh @ 1.3 m/kwh leads to 33/1.3=25p/m (on cheap home charging too). Equivalent mpg (ie m/g) is: g=4.55L, 4.55*145p=660p/g. 660p/g/25p/m=26m/g (ie mpg)... Which is awful, why bother?

What's frustrating is that it's a step backwards when compared to the L405. Tesla also have the weight issue but don't have these efficiency issues.

Yep I would not touch one if you’re paying 33p a kilowatt to charge it at home. ev opens the door to charging tariffs so unless you can work around charging it at certain times on a decent tarrif stay clear of this phev. Get home plug in and forget about it, wake up to a full battery charged on cheap rate.

Tesla are way more efficient, JLR have work to do. That said given the extra capability in the RR , it’s shape and tyres I imagine it’s a tough technical challenge to avoid compromises. MY23 PHEV HSE

I have a P440e on order. The EV range was a significant plus point for me over P400e. Currently run XC90 Twin Engine with 20 miles at best EV range. Average mpg over last 4 years is over 55mpg. I achieve 30mpg on petrol only. With up to 50 miles EV range I expect a big improvement in overall mpg with the P440e based on my mix of driving.
I home charge at night at 10p/kWh (eight legged cephalopod) and free charging at work. Now it makes sense.

I did a petrol only round trip of 135 miles last night it was unplanned so the battery was flat. The journey app says 31.6mg going and 31.3 coming back mostly motorway and I wasn’t hanging around.

Cars sat fully charged now showing range of 56miles. The GOM is proving pretty accurate. MY23 PHEV HSE

Much as I respect Harry's honest reviews I think he has made an honest mistake in estimating the efficiency of the P510e on full electric.

Although the battery pack on this and the P440e is stated as 38.2 Kw/h it is also stated that the useable battery capacity is 31.8 Kw/h. Even if you take 50 miles range (I haven't heard of anyone getting less than that) you are looking at 1.6 m/kw (50/31.. Others have reported 60miles plus real world in warmer weather.

Home charging at night is widely available at 10p/Kwh (Octopus etc) and this gives 6.25p per mile (10/1.6). using D3RM0's requoted figures that gives an mpg equivalent of 660/6.25= 105mpg.

I don't understand the comparison with Tesla. Tesla don't make PHEVs so they don't carry round a big lump of an engine let alone the offroad gubbins- they are optimised for aerodynamic road cruising. A better comparison for JLR would be the iPace efficiency against the Model X. My previous I Pace did around 3m/Kwh on average across the seasons. A quick google shows around 2.3-3.1m/Kwh for the Model X which if true means they are not far off each other.

Harry's review did also put me off somewhat. I'm in a Disco currently which is my first SUV as been a bit of a petrol head in the past with fast saloons but I really enjoy it. Have been considering switching out to a Range Rover, more so now the Model S Plaid in RHD isn't coming.

Two things holding me back. One is the lack of parts and downgrades people are getting, even things like 3 zone climate when I have 4 in my Disco. The other is the power train choice. I had been considering a PHEV but not sure now and also 7 seats is useful on occasions to go places with my parents and kids without needing to take 2 cars.

So on fence over 510e or just a LWD D350. Then if it's a 510e I'd have to try the Sport also as giving up extra seats and yet to try either of them.

What are people actually getting in reality on a P440e if they just run in electric only? I think Harry's point is fair unless he's worked it out wrong that the previous PHEV Range Rover was more efficient which you wouldn't expect over a new one.

What I think is also interesting but how far will the full electric Range Rover go or just how big a battery will it need? If we get a real world range out of 50 miles out of this rather large battery it's going to stuggle to crack 200 miles even with a rather massive battery.
