Re this question over the value of the Autobiography trim level.

The primary reason I went Autobiography was that I was forced to do so as you cannot (just checked the Configurator again) have the P510e drivetrain on an HSE.
I wanted the higher power as it doesn’t appear to significantly degrade efficiency, as it will be more able to deal with the heavy car once the battery is depleted.

So, if you want a P510e then you start at ATB and then to very expensive SV, which really isn’t worth the extra in my opinion. Cheers,

Ordered:
P510e ATB
Silicon Silver, Shadow Pack, Style 5127 wheels
Ebony + Extended Perlino Interior
Deployable Side Steps

I’ve probably ordered the worse value autobiography out having deliberately ‘downgraded’ some of the spec to get the vehicle I want. However, I’ll have exactly the car I’m after, and I guess it comes down to what you’re prepared to pay. Heart over head etc etc. Mine is fortunately still priced as ordered at launch when I guess the gulf between HSE & Autobiography was closer than it is now.

The only issue with the P510e AB is that it cannot be delivered with 4-zone climate. Top performance, ultimate spec IMO - except no 4-zone climate.... Not sure if the 3-zone in the P510e AB has fewer vents than others AB variants with 4-zone, nobody seem to have info reg this.

We're still not sure if we should downgrade from our current P510e AB order to the P440e due to lack of 4-zone. Pros and cons...

But the AB is worth the additional premium IMO, leather headliner, SV extended leather, SV carpet mats, meridian signature and the executive seats. AB = The full package (except for the P510e AB variant that doesn't have 4-zone...)

Hi aja500,

The straight 6 Ingenium in the P440e is a ‘detuned’ version through the engine management ‘black box’.
The P510e engine has the full 400bhp like the P400, but it also has the electric engine, making a gross peak power of 510bhp with the two outputs combined. Cheers,

Thanks for sharing that Ricky, I didn't realise but that's really helpful.

You may recall, I have so little faith in the JLR dealers and the supply of cars that I've actually ordered two variants, one is a P440e LWB and the other a P510e standard wheelbase. Only one will stay with me longterm, but what you've told me there has now made that decision a whole lot easier.

Many thanks

Our dealer says that there are physical (& weight) differences between the straight 6 engines in the P440e and P510e, not just different tuning maps. And that these physical/weight differences affects the ability to provide 4-zone climate in the P510e.

Doesn't the P400 have electrical supercharger in addition to twin turbos? Don't think the I6 in the P440e/P510e have electrical supercharger, only twin turbos? Or maybe the P510e has the electrical supercharger, and the P440e doesn't?

Yes, the P400 has a 48V supercharger which the plug-in hybrids don’t. I’d be surprised if there’s much physically different between the AJ300 engines in the two PHEVs.

A bit off topic, but if the only difference between the two I6 (AJ300) PHEV engines is the map tuning, why wouldn't LR offer the P510e in the LWB version as well?

Can’t see that, short of bolting a turbo from a supertanker onto one of them, there will be an appreciable weight difference between two variants of the same single-turbo engine - there will almost certainly be a much bigger difference between the AJ300 and AJ300D, and you can have a LWB diesel.

There is a 40kg+ weight difference between the 440e and 510e vehicles. I can’t believe 3 zone climate is heavier than 4 zone so there must be something else making the 510 heavier. A mapping change doesn’t make any weight difference either. I can’t see any other spec changes that would make a difference either so there surely must be a difference to the engine.

Agree with you, IjM! There must be some physical properties (& weight) with the P510e I6 engine that prohibit LR from using it in the LWB version, and also prohibits them from using it together with 4-zone climate in the AB trim (4-zone should be heavier/take more space than 3-zone, I guess).
Unless the weight difference between the P510e and P440e is purely related to the Dynamic response Pro (& torque vectoring) hardware that is standard on the P510e??

Bigger battery? Only Range Rovers since 1988

I don’t know the answer, but (as usual), some of the figures in the spec sheet look wrong - eg. P440e LWB has clearly incorrect maximum vehicle and trailer weight. If correct, there must be also spec differences accounting for the varying difference in SWB vs LWB weights (eg D350 SWB, 2505kg; D350 LWB 5 seat, 2569kg. P440e SWB, 2770kg; P440e LWB, 2810kg).
