Thinking about a D3 but unsure V8 4.4 vs TDV6
Good afternoon all,
I am giving serious consideration to entering the world of the D3. In the past I've had Defenders, 2 Vogues and 3 RRS's and have endured my fair share of issues, as well as plenty of happy motoring.
I've looked in here at some of the commentary in regard to the merits of V8 vs oil burner and am leaning towards the V8 as I don't do huge mileage, love the sound and have had too many issues with TDV8 engines & turbos in Rangies and Sports. The turbo requiring body off on the Sports is not a great piece of design as far as I can ascertain and I'm also aware of a fair few TDV6's which have endured engine failure.
Diesel would clearly be marketable from a re-sell perspective at some future point but are the V8's viewed as more reliable (55 or 06 Jag engine)?
Also if you compare a decent condition 55 plate HSE example with around 100k on clock, how much cheaper should the V8 be to purchase? (my guess is £1500 but interested in peoples views)

Here in the US we're not allowed a choice. V6 or V8 petrol only. No prizes for guessing which I went for....on a long highway run I was getting about 25mpg and around town average about 13mpg.
For a large heavy vehicle, stomping the go pedal is still surprisingly satisfying unleashing the Cat

I haven't seen a reduction in price over the v6- if anything they seem to be at a slight premium.

Are these mpg with the g being a US g? If so to get the imperial mpg multiple those numbers by 1.2.

Those figures are not bad for a V8, if you don't do the miles go for the petrol.Displaced Yorkshireman.

Thanks all. I'm not too concerned about the fuel consumption having had a V8 4.4 RRS in the past it was not too bad!
CMG, yours looks a nice vehicle although I suspect you have the steering wheel on the wrong side!
The key for me is understanding if the V8 at 100k is likely to be any better than a TD6 from a reliability perspective as I would really like a solid power unit and given V8 has no turbos to worry about I'm thinking it might be a better option.----------------------------------------

Well I have the V8. A 2008 HSE and before this I had a Full-Fat Range Rover TDV8.
I bought the V8 mainly because I much prefer the way petrols drive, cost less to service and the distinct lack of mess around filling up. Oh and I like the peace & quiet too. The V8 is significantly quieter on a run. A member on here (bp) was in my car recently and he commented that it was eerily quiet.
However, if you do any kind of towing the diesel is vastly superior at doing this job. I do have a caravan and accept that I need to work the car when towing. The diesel has way more torque low down in the revs so it tows a lot better, whereas the V8 has plenty of power but it's all up around 3-4000 rpm. And there are no re-maps out there for the V8 to increase low down torque, it's just not a characteristic of a naturally aspirated petrol engine. Now, the supercharged Range Rover is a different beast. Bags of torque there 8) (and a huge thirst to accompany it)
95% of the time I don't tow so I much prefer the V8. real world mpg is 18 around town, 26 on a run, your average will show about 22 and drop a lot when towing. That said the diesel isn't hugely better, probably about 20% overall. Factor in the extra cost of diesel (about 5%) plus the extra servicing costs and it closes the gap a bit.

When I was buying mine, there was an identical spec V8 for sale, had a few accessories like the A frame and spots with rear ladder etc. Only £500 difference in the 2.
However, I do 13k a year and even my best man maths couldn't get the figures to work in its favour.
It would have to be LPG'd to make sense and that's an extra £2-3k plus the valves aren't up to it so you need better heads to run it unless you like pouring in flashlube every 2/3rd fill up. Head work is another £2-3k. So would have been £17.5k worst case. Way out the budget.
Shame. If your not doing huge miles then the V8 is the one to buy.

Rest well old friend, your work is done.

I'm liking my V8. Getting about 24mpg on a long run at 65-70mph.
I don't do the mileage to justify the huge premium that a diesel attracts down under so I'm hapy pocketing the $15k saving and get to listen to a V8 that can pass double road trains without much thought at all 2011 D4 SDV6 HSE

Haha thanks! I think yours in on the wrong side!
Long term durability seems good on the V8, I'm up to 103k on mine and besides regular oil changes, the only thing done to the engine is a MAF sensor. Had a bad tstat and one cooling line fitting burst, but you could have those issues in a TD.17 Discovery 5 HSE Si6, Fuji White on brown | 07 LR3 SE 4.4 Java Black on Alpaca

I've owned many V8 RR's and Disco's over the years and it used to be a simple decision, because most of the diesel engines back in the day were, shall we say some what agricultural. But things have moved on, the TDV6 is a far better unit. Power delivery is seamless and although delivery is turbo induced and up to 30mph not as swift as the V8 once in it's stride there isn't a lot of difference and to be honest if you want a lot more you should be looking at a sports car rather than a lumbering 4x4
And once the novelty of a heavy right boot has worn off, and believe me it will when you start to struggle to get 200 miles out of a full tank (quite easy to do when booting it) and you start driving like Miss Daisy you start to ask yourself why you got the V8 in the first place.
I LPG'd my V8's in the end, which is great until you load the boot up and find there isn't any room left for the spare. Or you run out of gas and the garage you had lined up for refilling has no LPG so you cover the next 100 miles on petrol, not as bad as it used to be, but you do have to be organised with LPG.
I have just pulled up on the drive having been from London to Newcastle and back, I did it on one tank of diesel and the the comp says I have 55 miles left, I covered over 550 on my trip, no V8 will get near that and I also had the luxury of an empty boot for luggage
I'm not knocking the V8, LPG'd or not, it's a cracking motor with a fantastic engine. But for ease of use and running costs it has to be the TDV6 IMHODiscovery 4 HSE
