P400e - engine starting briefly then stopping. Healthy?
Discussion
Hi all,
Had my FFRR P400e for a while now, and most of the local journeys I do are purely on electric only. However, sometimes, the engine starts eg when it's below 5 degrees outside, if I use the power steering a lot, accelerate quickly but then the engine will switch off soon afterwards.
Now, I always grew up thinking that after starting, you should let an engine warm up before switching it off. Does this not apply to hybrid engines? Or is the long term health of the engine being sacrificed for the legislation friendly economy that this brings?
I've been meaning to ask this for a while - so interested to see what others think.
Thanks in advance,
Ed

I think that this is just how JLR set it up to work. I really wouldn't worry about it.
I wouldn't say I'm worrying about it. Just interested how it goes against the way I've always understood you should treat car engines. It's clearly set up that way, but how do they mitigate the damage you'd expect with running an engine for 45 seconds or so. I have the same, and have thought the same. Over the recent weeks I have been turning stop start off and using the save function to force the engine, once warm I allow it to do its own thing.
I can't imagine that many short bursts firing up when super cold are good for the long term wear of the engine.
I suppose it depends how long you plan to keep it...

yeah mine does the same, its clearly going to cause more wear than starting it and letting it run up to temp before restarting it, however i guess a lot might be offsite by the lack of actual use the ICE gets, my cars done 1600 miles now and i recon probably less that 400 of that is on the ICE... so at this rate it'll never get ran in!

Thanks for the replies. Yes, it's interesting - I'd love to know how many of the 17k miles I've done have been electric vs ICE. I don't believe there's anyway of knowing, but most of the day to day journeys I do are on just electric.
If you use the Land Rover app, you can download all the data to Excel. For me, of the 9,653.5 miles that the app has recorded, 4101.2 miles were EV (42.5%), making my average fuel consumption 40 mpg. Iv wondered this before as Iv always been a ‘start and let warm up’ person but these hybrids tootling about on electric then when you jump on a slip road are started up and immediately under a decent amount a acceleration can’t imagine it being good for then engine?
On a side note how are you finding the P400e? Iv been looking recently at the 3.0 diesels for towing but I don’t think my daily usage would be enough for a diesel with DPF etc and I like the thought of creeping around on full electric.

I love the P400e. I've had it two years now after it replaced my L405 V8 diesel. Very satisfying how many journeys you can do on electric alone, and the silence really suits the Range Rover. I miss the growl of the V8, but I get my engine noise kicks from my other cars. On a side note how are you finding the P400e?

plus I have free chargers at my work looks like a very good option.
that would make it a no-brainer for me.. having access to free electricity is a massive bonus, i did a week on the IOW last year, i spent £3.50 on electricity (which saved me £4.50 on parking ) and did over 250 miles using free charge points Gassing Station | Land Rover | Top of Page | What's New | My Stuff
