D4 2.7TDV6 and 3.0TDV6

[Sleeping Wood]

Hi people, First post. I have been lurking about for a few weeks and have searched through many posts, read FAQ etc.

I am considering purchasing a D4 and cant find much info on how the D4 2.7 and 3.0 compare against each other for on road use.

I would be using the vehicle for towing a van (2.5 ton) and don't anticipate a great deal of heavy off-road use. I have not had the opportunity of driving either of these vehicles yet so I thought I would ask if any member has done a comparison between the two.

The D3 2.7TD could also be an option based on my intended use so I would be interested if anyone has compared the three vehicles... Thanks for any advice.

I can only suggest driving both and then start to make up your mind as to which will suit your needs.
I admit I am biased as I have the 3.0 and is nothing short of being a fantastic vehicle.
You have come to the right place as you have obviously decided you want a D3 or D4; now you are looking for information to narrow down your choice of models. There are many wise people on this forum who will give you very good advice.
Hope you find a good vehicle.

There is no doubt the 3.0 is the more capable vehicle engine power wise - it will clearly out perform the 2.7 which is no slouch itself. The issue is the extra $10-$15K extra for the 3.0 worth it.

Also there are threads on this so if you do a google search on aulro they should show up.

I have had both 2.7 LR3 and 3.0 litre RRS.
Engine wise the 3.0 litre engine is light years infront. Instant power with no lag. 600nm of torque within less than a second of opening the throttle.
Its worth the money, no comparison.

G-day Craig
The wife & I looked into both these models & engine options when we were looking at replacing our TD5 Disco. We test drove both engines in both models.
Discovery 3 & D4. The 3ltr was exceptionally smooth & responsive. The 2.7ltr which we were told by the dealer was a brand new complete engine replaced in this vehicle because of a total failure ( he would not elaborate further ) was coarse in comparison but still very impressive in performance to our TD5. What concerned me about the 2.7ltr was its use of belts for cam timing & there expense of replacement compared to the 3ltr using chains. In the end we went the other end of the spectrum & purchased a TDCI Defender. But thats a whole other story. I still think that if your budget allows for regular specialist servicing or you truly can do it yourself then either engine would be a pleasure to own.
Good luck Hunting.
Regards Chris.:)

I think that the 3 Litre with chains is the petrol, I was referring to the 3 litre diesel with twin turbos, which still has rubber belts for cam timing unfortunately.
No comparison between the 3 litre diesel and the 3 litre petrol!

There is no 3 litre petrol - 4 litre V6, 4.4 Litre V8 and now go fast V8

If cost isn't an issue go the 3l - the only advantage the 2.7l has other than cost is it could be argued to be better for offroad because the model allows for 17" rims - whereas the 3l will come with 19" with an 18" aftermarket option. I see that offroad performance isn't a big issue for you though.

If cost is an issue, the 2.7l is still a great motor and does most things pretty effortlessly, including towing. Although I guess the extra low down torque of the 3l will be even better for towing :)

They're an awesome towing vehicle.

[Barryp]

Gary,
Obvious blunder, of course the petrol is 4 litre.
Confusing bit was the reference to chain cam drive by Bess!

Most of the discussion on this topic of comparing the 3.0 with the 2.7 on other threads has been comparing the full spec 3.0 with the 2.7.

But now we have the low spec 3.0 with not a lot more power but still quite a bit more torque - so obviously this 3.0 will be ahead of the 2.7 but by how much - is it really worth getting this 3.0 noting the low spec 3.0 replaced the 2.7 in the new car line up.

Sleeping Wood,

I have posted the following sentiments before.

I drive 2009 2.7TDV6 D3, now with circa 87,000 on the clock. I have loved almost every minute of ownership.

Never once have I wished for more power.

I do not tow regularly so that is not an issue for me.

I do use it off road but on 18 in rims, i have not yet felt the need to get 17in rims and would not be put off by 19in rims on the D4 to be honest.

I often load it up with family and camping gear and as above I have never felt under powered, I am always surprised how strong the 2.7 TDV6 is. It will cruise fully loaded at or above the speed limit all day comfortably.

If you get the 2.7 you will be happy.

However by all reports however the 3.0 is just that much better.

Hope that helps.

Hi Craig,
Back to your original query. You were wanting advice on whether to purchase a D4 2.7 or D4 3.0.....or maybe a D3 2.7, for mainly on road use, and towing your 2.5 ton van.
I had the D3 with the 2.7 and found it adequate for towing, however ended up having a ECU power upgrade installed, as I found it lacking in low down torque.
I then bought the D4 with the 3.0 and was blown away by the difference.
The low down pulling torque and power was way beyond the improved 2.7.
If your main use is to pull your 2.5 ton van, go the 3.0 for sure.
One of my mottos as a builder is "the job is remembered long after the price is forgotten". Same goes with the 3.0.
I spent the initial $ at the beginning to purchase the 3.0 and never looked back.

Cheers, Craig

If you are looking at new? then the price saving on a Low pressure 3.0Ltr is hard to go past. It is greatly improved from the 2.7 (which I don't have a problem with as I own one) & obviously not as powerful as the High pressure 3.0Ltr.

Seriously consider having a look at both, I think you will come away Very surprised & with a great saving still in your pocket.

Good luck.

Thanks for all the reply's people,,, great information! :D Sniegy... I was going through Carsales over the last two days and noticed the MY13 has reduced power (down to 155Kw from 180KW for the 3.0l motor for MY10 - 12) the motor in MY13 is also listed as a V90 as opposed to a V60 configuration. Anyone know why LR has done this? and is the V90 motor a belt or chain cam drive..... I am far more comfortable with a chain drive:cool:

[Bess]

Craig, I only mention the Belt/Chain issue as an servicing cost. The 2.7 Ltr Td as fitted to the Discovery 3 & early D4 as a cheaper option runs two belts for timing. The belt at the front of the engine that controls cam timing is the one to worry about. If it has not been changed at its service interval its not a matter of it it will break but when. Repairs after that would make your eyes water. The rear belt times the fuel pump. If it breaks you just stop then walk. The 3ltr engines use chains so have a much longer service life. If you were considering an D3 V6 Td with over 100,000km you would want to know the service history. regards Chris

Same story for me, glad I have never driven a 3.0 because I don't know what I am missing, but often amazed by how good my 2.7 is. I have never had a driving moment when I have thought I wish I had more power although the little lag on take off can be annoying until you get used to it and figure out how to work around it.

[Sleeping Wood]

Still doing my homework on the 2.7 and 3.0 liter motors. Just trying to establish servicing costs etc.
From what I have read the transmission on both these motors is the ZF 6HP26 requiring ZF Lifeguard 6 fluid, pan and filter replacement at some service interval. I have searched the ZF Friedrichshafen AG | Startseite | Antriebstechnik und Fahrwerktechnik (http://www.zf.com) but am unable to locate the service kit number for this transmission. :mad: Does any member have the service kit number?

The shop on AULRO also has Dave's Interesting Things - LR3 Collection (http://www.davesitshop.com/davesitshop/index.php?_a=viewProd&productId=135)

Land Rover Discovery 3 (LR3) Repair Manual. This manual I imagine would be very close to the D4 but would not have the 3.0 liter motor, Is there any manual that would cover the D4 3.0 motor.

Thanks again Craig

[SBD4]

I believe the 3.0L is ZF6HP28.

ZF themselves should be able to give you the info you need (and the kits). There is a branch in SA.

Sleeping wood - the MY13 still comes with the 183kw model. It's just the base TDV6 that comes with the 155.

[Barryp]

Hi Bess,
The 3 litre twin turbo motor still uses the same cam belt system as the 2.7 litre motor (notched rubber belt dirve) so no saving in belt replacement service cost.
Only the 4 litre petrol v6 uses chains!

G day Barryyp, Thanks for that mate, We came very close to purchasing what was a very tidy D4 Td & that decision was partly based on the Stealer telling me the new 3 ltr ran chain rather then belt. I stand happily corrected & wiser for the knowing. He never did tell me what had failed in the D3 we looked at but it was enough to scare me off a little. Still think they are a fabulous thing to drive thou.
Regards Chris

[Sleeping Wood]

So 2.7 (MY10 -12) and 3.0 (MY 10-) liter diesel motors motors are all belt driven,....
Its only the petrol ones that have a chain drive cam ?

[Barryp]

Yes, thats what my research shows. The cam belt cover is virtually identical between my LR3 2.7 litre and my 3 litre RRS.
It would have to be a totally different design if it had to keep in lubricating oil etc for a chain drive.
Regards
Barryp

[sniegy]

Discovery only.
