P400e v 5.0 V8

Trying to make a decision between a hybrid and a Petrol V8 (Non-SVR), but can't seem to make my mind up.

I do 10-15 miles per day with a couple of long European journeys each year, so annual mileage about 7k

The 5.0 V8 is a 2015 with 45,000mls. Pre-facelift is a negative, but from my understanding it's the least troublesome of the engines, which is obviously a positive.

The P400e is a 2020 with 35,000mls. Post-facelift and much lower day to day running costs, but seemingly the potential for more things to go wrong compared to the V8.

Price wise there's not a great deal of difference.

Unfortunately a facelifted 5.0 V8 is out of budget.

Worried about going for the older, more dated V8 but also worried about the potential problems a Hybrid could throw up!

Any advice would be greatly appreciated.

My choice was between the P400E and the D300MHEV - so couldn't avoid some electrical tech.

Right now, I made the wrong choice. When I bought it, I was between jobs and wasn't sure whether my next commute would be 120 miles a day or much less. As it turned out, I don't have a commute as I'm based from home 99% of the time for at least the next 6 months so it just sits there until I pop out to the post office or supermarket. So with a P400E I'd have filled up maybe twice since I bought it and done 98% of my driving on electric, and instead I'm looking at lots of 17mpg interspersed with the odd 35 when i do go farther afield. So it's cost me maybe £300 more than it needed.
Insurance on the P400 is more but not by a relevant amount.

But - I plan to have the car for 10 years - JLR electronics aren't exactly at Honda levels of reliability so can I trust it to be impeccably reliable for that period?
Probably not if I'm honest, and I was concerned that if I did long commutes, how is a P400 once the battery is depleted and then would I be willing to give up the low revving nature of a diesel. So I bottled and bought another diesel. 2021 L494 D300MHEV Autobiography

IMHO, there’s a reason why the P400e, newer with lower miles, is valued lower than the v8. The market is rarely wrong. Hybrid tech may have horrendous costs if something goes wrong. People here maybe able to offer specific advice and experience. Cheers,

Yeah - if I had to make the same decision now, with hindsight, would I?
I really don't know.
The P400E makes a hell of a lot of sense. If I was 'normal' and leased for 3 years then probably I would have taken the punt. After all, you get 2 years warranty from the dealer so an additional year isn't going to break the bank, and the idea of an electric RRS is compelling. 10-15 miles a day means your fuel costs will be £0. Which as against a V8 means over a week that's £0 vs £40 - quite an argument.
In your case, you get the later tech which is very nice too.
I'd say it greatly depends on how long you intend to keep it.
Not sure I'd want one that's 10 years old but a 5 year old one is quite an appealing proposition. 2021 L494 D300MHEV Autobiography

We've a customer with a 2018 P400e L405. Owned from new
Average fuel economy is usually 50+mpg

0 issues with the battery or hybrid system
1 engine management fault, due to faulty VVT solenoids (common issue)
2 failed rear shocks, due to corrosion (understandable, given the salt we put on our roads Rolling Eyes )
The rest has been servicing, or wear/tear Thumbs Up


BUT! It's not a V8 Big Cry

And, conversely, the market is prone to believing myths and "a mate of mine knew a bloke" stories. People are put off second hand PHEV/EV because of the "everyone knows the batteries will need to be replaced in a year or two" stuff. Sure, some might but some will give several more years of service. So just like the ICE component in every non-EV then - "everyone knows" the SDV6 will snap its crank, for example.

There's a lot of fear around batteries but that's mostly due to a lack of data available to punters. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Lack of data is key, but equally so is the immaturity of the technology. It's not asif there are lots of 10 year old LR hybrids running around so the fear is, nobody truly knows what the lifespan is.

We can be pretty sure that diesel engines will do 200k+ if looked after. Exceptions are rare, so whilst the IL6 in my D300 is effectively brand new, I can rely on years of experience generally and the fact that the basic Ingenium platform has been around for 10 years and early issues like timing chains are sorted.

Early EVs like the leaf have horror stores, added to by stories of £20k bills for teslas. Additionally the lack of after market repair services and expertise is worrying. We know things are vastly better today but it's still not exactly bedded in.
There was one of the usual youtube suspects with a P400E not working. He took it to some other youtuber who spent a couple of days figuring out what was wrong, disproving the official JLR instructions and sorting it for minimal cost in the end. But I don't know anyone who could do that for me in the same circumstances. In a few years I suspect I'll know many people but right now, I'd be facing main dealers and their parts cannons. A terrifying prospect given the cost of EV components. 2021 L494 D300MHEV Autobiography

Thanks everyone, some really useful input there.

As 41jules1967 says, some of the fear is down to lack of data.

I guess as a day to day proposition the P400e makes a lot of sense and seemingly the only recurring 'negative data' out there is that HV Heaters can be prone to failure, which obviously isn't ideal but in the grand scheme of things isn't at the level of a snapped crank.

I live in Jersey and they are hitting imported vehicles with huge duties based on CO2 emissions, which is skewing the used car market over here.

A P400e would cost £300 emissions duty.
A 5.0 SC V8 would cost £10k emissions duty (rising to £12k from 1st Jan)

The P400e in my original post was a UK based VAT qualifying car, which i could get landed in Jersey for about £32k.

The 5.0 V8 is a local car and up for £27k.

As you can see, this poses a bit of a dilemma, the 2021, 29,000mile car is only £5k more than the 2015, 45,000mile car.
