Thread: Discovery 4, 3.0L vrs RRS, 3.0L Diesel

From what I have read both vehicles are based on the same chassis. YES
The RRS has a shorter wheel base compared to the D4, YES
and a different suspension that maybe subject to "clunks" in the front end after xx kilometers (due to the different suspension design)? CLUNKS can be attributed to the DYNAMIC RESPONSE system on the sport only, the worm drive gears wear marginally but in a 2 1/2 done vehicle it sounds worse than it is. Can be easily fixed by removing fuse 54 from memory & issue gone. But downside is the system doesn't work.

Does the D4 suffer from this same problem?). NO
I believe this is a subjective thing and isolated to individual vehicles and may be only a RRS issue?

The D4 has the white smoke issue with the turbos, (not sure if RRS has the same issue ? , or it has been sorted by LR from MY-- for both vehicles), I think both may have the same smoke issue but am happy to be corrected... it's the same engine. SAME ENGINE in both vehicles, the Sport is programmed to give slightly more power (as the Sport name suggests)

I have test driven both these vehicles, but I would like to hear the opinions of forum members on the performance and characteristics of both.

My use for both these vehicles would be for towing and limited off road usage.. I am looking for an objective comparison between each vehicle. I am looking at MY10 until new.

Thanks

Answers in your questions above, Gordon will probably chime in as he has a Sport 10 or 11MY & it is one very nicely kitted out vehicle.
He lives with his on a daily basis.

To all intense & purposes, on the mechanical side of things, they're pretty much identical.

The suspension is tuned slightly differently in the RRS, it also has the ACE system but the clunks are there on BOTH D4 & RRS as it's usually caused by worn bushes. As for more power... No. The only difference is if it's TDV6 or SDV6, both of which are fitted to the D4.

Performance wise, the D4 has similar performance & handling to the earlier RRS TDV8.

Franky, I'd test drive both and go for what you prefer.

For working out which vehicle suits you best I would assume that mechanically they are essentially the same.

The big issue is the usability of internal space - as mentioned the wheelbase of the RRS is smaller so load area is smaller from a start. In addition the D4 is shaped like a fridge so the space is very usable where the Sport being sporty is compromised - mainly by the slope of the rear upper door. It really compromises the loading of boxy stuff with the rear seats up and you have to make sure the heating element in the rear glass does not get damaged by large items being carried.

However the Sport does look so much better than the fridge with wheels.

For your usage, you could probably consider the two mechanically identical, depending on spec - eg my Sport doesn't have the Dynamic Response option, so other than a slightly firmer ride, suspension is identical. Ground clearance and off-road angle differences are basically down to the differences in OEM tyre size, and the transmission in the Sport is programmed to give a more sporty experience.

The Sport has less room inside, but if you're only travelling solo or as a couple, it's adequate. There are less aftermarket options for the Sport (eg no snorkel, no bullbar), but that is slowly being addressed, albeit they will be more expensive to kit up.

The base Sport is pretty similar to the HSE D4 in spec, so a fair bit of "creature comfort", and the "cockpit feel" in the front seats is quite different to the open feeling of the D4. The D4 has a longer wheelbase (by 140mm), so isn't quite as nimble, either on or off road.

The Sport is marginally more economical on the open road due to its shape, but around town they're identical (if on the same tyres). It's quieter inside than the D4 (more insulation), but less storage space (useful little pockets, holders etc).

The specs and trim options on the individual vehicles you look at will probably make more of a difference than any of the above, other than the internal load space.

Cheers,

Gordon

Was the Dynamic Response system fitted to all sports?
The current MY13 brochure lists it as an option on SDV6 3.0L and SDV6 3.0L luxury models.
The vehicle I am looking at I believe does not have it. Is there an easy way to tell?

The Terrain Response dial will have an extra setting - it was standard on the Supercharged petrol engines.

Hi Sleeping Wood,

I have a 2011 3 litre diesel RR Sport and it definately does not have a Dynamic Response System (ACE?). It does have the standard terain response system as fitted to the D4.

Was standard on the Supercharged & 3.6Ltr TDV8. All others was an option. 05-09MY.

Std again on S/Charged & again an option on all others. 10MY+

Easy way to tell is if it has Brembo's & minimum 19" rims.

Cheers
