Hi All,
I just got a 2021 P400e with just shy of 50k miles on the clock.
Today I tried to see how far the car could go on EV only. I managed 14 miles before the petrol engine kicked in. The driving style was half town and half motorway at 50mph. Temperature was 8 degrees and the heating and heated seat was on.
Does this corresponds with others users experience or might there be something wrong with the traction battery?

I’ve looked into buying a P400e and research did show that sort of figure is about right.

Claimed EV mileage is a bit like claimed MPG figures, totally unrealistic. Achieved for 2 minutes under lab conditions but never to be seen again

I run a full electric van with a claimed range of 210 miles
I’ve never seen more than 155 miles. And that’s in high summer with nothing on.

Running the heater, exceeding 65mph and temperature are the biggest drain and range can fall as low as 120 miles in the depths of winter.

That said 100 miles is more than enough for me and charging at home on a cheap tariff means I’m saving between £200 and £300 per month on diesel, so it works for me. But if you have to use the public charging system I would stick with Petrol or Diesel.

I charge overnight at 7p per KWH, I noticed a public charger the other day charging 89p per KWH

Sorry, went a bit off topic there, but I would think 14 miles is about right.

Thanks, appreciated.
I also have a number of EVs, so am familiar with difference between stated and achieved range.
Want to know if what I am getting is normal and that the battery is ok. I just got the car and the net is full of advice of what the range prediction says, etc, but not a lot of information about what real range people actually get.
Would be good to hear from any P400e drivers on the forum.

Hi, from the beginning, when fully charged, the displayed range was almost always between 21 and 22 miles. However, the actual range, which depends significantly on temperature and other conditions, was closer to 14 miles. These values remain valid even five years later, so I assume there hasn't been any significant battery degradation.

Thanks - this is reassuring. I don't mind the low EV range, but just didn't want to have a dud. Interestingly I put the same question to ChatGPT that gave below answer which seems to correspond with my experience:

FROM CHATGPT:
A 4-year-old Range Rover L405 P400e (the plug-in hybrid model) with 50,000 miles on the clock and operating in around 5°C (41°F) urban conditions will typically achieve 8 to 14 miles of real-world electric-only range.

Here’s a breakdown of why:

- Original WLTP range: Around 25 miles (40 km).
- Real-world expectations when new: ~18–20 miles in ideal conditions.
- Battery degradation: After 4 years and 50k miles, degradation is likely around 10–20%, reducing usable capacity.
- Cold weather: At 5°C, battery efficiency drops, and cabin heating draws more power. Expect a 20–30% hit just from temperature.
- Urban driving: Regenerative braking helps, but low speeds and stop-start traffic don’t fully offset range loss in the cold.

So in your described scenario — 4 years old, 50k miles, 5°C, city use — you're realistically looking at:

Electric-only range: ~8 to 14 miles (13–22 km)

I get 18-25 on mine subject to weather, averaging around 20 miles most of the year, A warm day can do 28 miles. Always on charge and at office and i any put fuel in myself for weeks, over a month and even then its £100 to fill Lovin the P400e

Never had 28 miles. When fully charged at 100% it says 30 miles. In real life at a guess 20. I normally let the car decide whether its petrol or leccy
Once when fully charged saying 30 miles I reversed out of the drive & it was down to 29 miles. Pretty sure my drive is not a mile long

Has anybody experienced any noticeable battery degradation. My read out jumps between 20 -31 miles, but since I just let the car do its thing (instead of EV mode) I can't actually tell what pure electric range I am getting. I think it's anywhere between 10-20 miles or so.
I came from an EV and was much more focussed on the SOC, but now just drive the car.
