We look after a few P400's. They have all at some point flashed up an EML for the VVT solenoid

Done a set of rear shocks on one. Hideously expensive, and HV battery needs raised to access top fixings, made even worse as it had executive seating. Not a fun job Laughing

Otherwise, just the usual wear and tear of a typical 405

Best mpg we've seen from them is 86mpg. He charges it at night, that gets him to work and mostly home on EV alone.
Economy is almost on par with a 5.0 SC if you use it on dino juice alone Thumbs Up

I think your talking about the P400E Mikey ? the question is about the 3.0 petrol MHEV. 2021 P400 Silicon Silver AB

My experience of the P400 MHEV:

Touch wood I've had zero issues with mine so far although Ive only done 10,000 miles.

It's plenty fast enough for a car of this size (5.6 0-60) with good torque (twin turbo plus an electric supercharger) and it never feels underpowered, the only time I've used sport mode is the obligatory exit from French toll booths Laughing

You get mid 20's on short runs but can get mid 30's on the motorway without driving like a granny, this coupled with the larger fuel tank gives you a great range for long journeys.

On the down side its not seat of your pants quick throughout the whole range and the sound of the engine isn't anything to get excited about but for me I wasn't really looking for those things from this vehicle.

If economy / tank range is not of any importance to you and prices are not much different I would probably go for the 5.0 supercharged, you don't hear of many issues with that engine and I think there are probably more 5.0 for sale over the P400 so you may get more choice for the spec you are looking for.

When I ordered I think the difference between the engines was about £5K, that coupled with the reduced tank range due to MPG meant it wasn't worth it for me.

Happy to answer any other questions if needed. Thumbs Up 2021 P400 Silicon Silver AB

Thanks for the response. I’m also eyeing one of these as a potential next RR. But finding a review of one seems to be fiendishly difficult.

I think our next SUV, assuming we can justify the case for having one now the kids are grown up and we aren’t doing long uni runs loaded to the roof, is between the MHEV petrol L405, the 3.0 pure petrol SC L405, a Cayenne e-hybrid, or possibly a [R]S6 Avant.

It’d be nice, but not vital, to be able to do short jaunts around town on leccy. These days our use case for an SUV is (a) holiday airport runs, (b) dump runs, and (c) getting the 10’ Xmas tree home. The cost of parking at Heathrow is rapidly making (a) seem pointless (the hated Addy Lee is a lot cheaper). A tree would fit in the mini with the roof down. None of our other cars are suitable for dump runs, but a large car specifically for dump runs is a really stupid idea. OTOH, I do love a FFRR and to be honest it is a much nicer GT car than either the AM or the Porsche 85% of the time. The 15% when the road opens up and Waze says no one is looking … well, no one can cater for that. Range Rover 4.2 SC
