Hi,

Now looking for replacement for Discovery TDV6. Always wanted a Range Rover. So been browsing on the Internet. Pricing range means this would be a Range Rover Sport.

My question...as per title....which engine would you pick?

Let's us compare engines and reasons for and against. We can say for this thread that both cars are identical except the engines and relevant to fitting those engines specifications.

Thanks for the potential for an interesting thread.

what is your price point out of interest? Only asking as 4.4TDV8 with 8 speed Vogue with extended warranty (if you are lucky) can be had for close to $80K these days, even with less than 50K's. The pre MY11 3.6TDV8's ofcourse are much cheaper again.

TDV8 for me.

Power, torque, noise, no timing belts!

And 8 is 6+2

I love my SDV6 which only shows how much I'd love a TDV8

It's maths.

Depends on your priorities and budget. The 3.6 TDV8 is a lovely folly but it's much thirstier and heavier meaning less range and payload. I haven't driven a 4.4 but on paper they're a much stronger argument on those points.

Hi.
Looking up too a 2008/9 Max.

How thirsty is the V8 compared to TDV6?

Interesting point about heavier engine and pay load. Had not crossed my mind!

Hi.

If you're looking at MY 08/09 then it's between the 3.6L TDV8 and the 2.7L TDV6 rather than the 3.0L V6, which means there's also some potential brake calliper size differences and subsequent rim-size choice considerations - 17 and 18" v 18 and 19" (make a coffee and do a search on that one!).

Re your economy, the 2.7L isn't as economical as the 3.0L but still way better than the TDV8. In our 2010 2.7L D4 I used to get 12L/100 around town and as good as 8.5L/100 on the highway (even with a 7x4 trailer), whereas in the TDV8 RRS we've been getting around 15L/100 and 10.5L/100 respectively (and towing has more of a detrimental effect). It translates to a conservative range in the order of 800 compared to only 600 kms. (NB I have another thread discussing what the heck might have gone wrong recently with the fuel economy on our TDV8, with lots of good thoughts...)

The payload for our TDV8 is about 530kg from memory and I think the 2.7L D4 (which could be more than the RRS even though the tare is about the same) is around 750? Someone will confirm or correct me on that....

All that said, I think the 3.0 is the pick, but there is definitely a price-jump for all the post-2010 facelift models.

I've done a bit of beach and road driving of a new SDV6 D4 to compare it against my 08 RRV 3.6. On the beach the RRV is better but the D4 is close in power & torque as the specs suggest. The RRV just seems to do it easier. On the road I think the RRV is quieter and nicer to drive against the new D4. However the D4/3 shape and rear folding seat design make it better for carrying gear. Fuel economy wise I doubt there would be much difference. My RRV uses about 13.5 around town and about 8 on the HW empty not towing.

V8...

But if it wasn't a 4.4, I'd rather a 5.0 Super Charged, the diesels don't do it for me in a Range Rover.

Hi Chilly,
TDV8 all the way, my TDV8 returns 10.8 l/100 all day every day. No timing belts, goes like a "stabbed rat" if you feel like it. I've had three TDV6's all 2.7's and I have also had one D3 V8 4.4, the 4.4 was an interesting piece of machinery to say the least.
Yeap well aware of the downsides of the RRS, however I like the look of them, they have a presence, Rimini red or Alveston red are my favourite colours I have a white one at the moment, right price, knew the history, wins every time.

Lovely to drive, very comfortable, tows well. Love it to bits...........

Cheers Marty.

Thanks all for input

You won't be sorry, very happy with ours especially now has Gordon's rims and D697's to go with the llams and remap. As there are just the 2 of us we don't really need the extra space of a Disco plus love the look of the rrs

There is just me...so should not need the space either. Had a look at your photos....very nice! I agree the Red is the colour to have in the RRS....but Silver it is!!

Hoping to pick up tomorrow. Just got to find out about payment. Hopefully a Bank direct deposit will be acceptable on the day!

I agree, but I assume the thought was it would take too many sales away from Range Rovers (which is probably the case).

Remap? What was your reason for doing this?

Understand that....already looked at BAS remap....just in case I need that extra power....ha ha!!!!

Hi Chilly,
Extra power............ how much do you need? That is greed............... having a "bit of being an idiot moment", I dragged an SS commodore off the lights a week or so ago whilst not coming out on top I gave the driver a bit of a fright when he saw a RRS door to door, not bad for a vehicle that weighs close on 1 tonne more......... It was just a bit of fun and not a race through the streets of Perth.

What sort of money were you looking at for yours?

Cheers Marty

Hi Chilly, it came with the remap when I bought it, the guy had it done for better towing - like it does not have enough torque for towing anyway..... ends up around 248Kw and 780Nm. :twisted: but I drive like a granny anyway...... but it is nice to have such power when you need it so it's not greed...... more like luxury

Wow. Austeve remapped his vogue with good results.

I also went for a remap on my TDV8 (Roo Systems in Brisbane) with new dual 3inch exhaust; still quiet - until you sink the right boot �� It's tuned for towing so low down torque - I think dynotuned by Roo at 276kw and 870nm or thereabouts up from 230/700. Necessary? No. But boy it tows a 3.5t van well!

Doea that mean there's a set of 19s with Cooper rubber collecting dust? *bats eyelids*

Hi Stuart, yep, 4 x 19's, 2 with new in October Zeons (I rock fractured 2 while away and had to replace them - serves me right for trying to get one last trip but of course the new rims hadn't arrived). Other 2 have legal tread, maybe 25% left. The rims have some marks from off roading. I have pics if you are interested. I am willing to sell them if you want to make an offer - the 2 new tyres cost me $400 each in the bush! They have done around 3k km. pm me if interested or email me martin.philcox@bigpond.com
