Real Life Fuel Economy SDV8

[Disco4SE]

Hi all,
New to this forum although have been on the Disco 4 forum for a while now.

Looking at buying a second hand Range Rover Sport V8 diesel and are interested in what sort of fuel economy everyone is getting.

Thanks in advance, Craig

Hi Craig. I have a hse sdv8. Goes like a train. On my daily commute I am averaging 7.7l / 100k. On a run 7/100k. Just upgraded from a 4.4 petrol so very happy with that.

[Pedro_The_Swift]

From what I read Craig,,, the SDV8 and 8 speed is about LR's top economy model,,,

anyone add some 2-3T towing fuel figures?

That is amazing for a V8 Diesel. The Landcruiser 200 series is way over that.

All the more reason to buy a RRS [smilebigeye]

Yep. Was really tough decision, I wanted the velar when it came out but not great off road and I needed something that can tow a 2.5t off road caravan. Was going for the disco 5 but mrs said just get the sport. Bit pricey but I’m saving $50 per week in fuel alone. Best decision I’ve made.

I should know in a couple of weeks. We have a 2.5t off road caravan. I’m guessing approx double what I gat now so 14-15l per 100k

Any others want to chime in?

Would be greatly appreciated.

I get 11.5L/100kms towing a camper trailer 2.2T.

Could probably get better of I didn't have lead foot.

Thanks for your feedback.

I am around 9.5/100 with mixed driving. Seem to be around 8.5 on highway journeys.

[Bails]

Filler up a few days ago and have done some mixed driving around town and trip from Wollongong to Sydney. Just happened to look at teh in car read out and it was 8.4/100. It does read optimistic but even allowing for this I am well pleased. I don't bother checking all that often but do know my usage is down from from last vehicle as I don't seem to remember when I last fuelled.

Amazes me Ford build it and dont use it more,,

A 3.6 V8 diesel would never cut it for them same as the Buick 3.5 they palmed off to the poms for the RRC[bigwhistle]

[Graeme]

It is the 4.4L and was built specifically for LR at the time. LR have been wanting to delete it replacing it with the lighter, almost same o/p, higher stressed SDV6 but customers keep ordering it.

I thought the 4.4 only ran for a few years then LR just ran with the 3.6 option only [bighmmm]

I understand that the engines along with the SDV6 are going into the smaller F trucks.

Also remember it is technically not a Ford engine - it is a PSA Powertrain engine. PSA Powertrain designed the engines and built them in a joint venture with Ford - Ford UK actually builds the engines as part of the joint venture.

The 3.6 was last fitted to MY10 RRS and L322 then the 4.4 has been fitted only to the MY11-12 L322 then L405.

I see as low as 7.9l100 on long trips like Canberra to Melbourne. My daily commute and average 7day a week use is around 9.8 to 10.5. These numbers equate to being almost exactly 1.4 optimistic. At the pump I am getting 9.3 real to 7.9 dash readout. Recently towed a car trailer to the NE of the state, some very hilly country around Scottsdale and ringarooma and returned home here with a 300tdi D1 on the back. In addition to seeing 110kmh up the odd hill, I still avearaged 14.5l/100 up and back, which was 800km.
These engines attached to the 8spd are just amazing !

I thought the V6 and V8 both used the same cast construction for the block ? Weight wouldn't be that great a difference ?

[Disco4SE]

Great feedback everyone, thanks.

Sounds like they are are great engine and way more economical than other turbo diesel V8's.

The Ford Ranger doesn't achieve those sort of figures.

Cheers, Craig

Enough of an increase to be felt in the ride and handling characteristics.

... and the L494 of course.

[justinc]

.... thank goodness for that.... there is no way I would probably have bought it as a V6... There is a HUGE attraction to the feel of that glorious V8. From idle to 4,500 rpm it is a sweet thing.

I think I jus described the beginning of a midlife crisis??😄

[Pedro_The_Swift]

beginning ??? [bigrolf]

[rar110]

I assumed the 4.4 was built at Ford’s Dagenham engine plant in Essex. However after reading a few articles it looks like the block is made in Brazil and assembled in Mexico. And is only fitted to Land Rovers. Quite surprising.

[Bails]

Did the 4.4 ever get fitted to the disco ?

[loanrangie]

Did the 4.4 ever get fitted to the disco ?No tdv8 was ever fitted to a disco.

[SBD4]

No tdv8 was ever fitted to a disco.
That really needed to happen in lieu of just dropping the petrol v8 from the D4 in 2013. Would have been nice to see it in the D5 and certainly as an option on the SVX D5 along side the petrol V8 (when ever one of those gets made).

[SBD4]

...and can you imagine if they released the new defender with a 4.4 in it?

I wonder if it complies with the latest emissions regulations.

It seems they put a V8 petrol in a defender but the logical way to go would have been the SDV8. Putting under powered 2 litre engines into work horses doesn't work for me.

[justinc]

Because the defender is unsafe above 130kmh, and wipers are useless above 90kmh...🙄😏

[Pedro_The_Swift]

take the moonshot diffs out of it,,,

[jtmesa]

Is the fuel economy reading from the dash accurate?

From memory i was getting 7.7's from my SDV6, but at the bowser i was getting 750-800ks for 70lts.... so cant be 7.7l per 100km

**Sorry just realised earlier posts confirmed my observation.

[Gregz]

Can your RRS do 0-100 in 4.4 seconds? Probably only matter of time before there is a RHD version of this.... with ∞ l/100km .

Just did 5000km BNE - ADL return and averaged 8.2/100 in our L405 SDV8. Bloody impressive!

That is impressive for a V8 TD.
I did Melbourne to Sydney and back in my Jeep Grand Cherokee TD and averaged 8.4 Lt per 100 Klm's which included running around Sydney.

Is that dash readout or by measured you mean at the pump?

[Bails]

At the pump. Read out was more optimistic at 7.8/100!

[justinc]

I know... when one read 7.9 I lept for joy, but it worked out at 9.4..😕😊😊

[discojools]

Well I have tried very hard to get economy reading on my recently acquired SDV8 but unfortunately I have got so addicted to flooring it that I am in double figures! I may calm down in the future....
Vehicle is actually better than I thought it would be so very happy so far.

[Bails]

They are great with the SVD 8 although I am getting a fault atm high pressure fuel sensor. Away from home so just resetting with my code reader. This has occurred before but after checked by dealer not been back for 6 months.

[Disco4SE]

Picked up my new (second hand) HSE SDV8 Dynamic Tuesday afternoon.......very happy [biggrin]

Topped up the fuel last night after travelling 650 Klm's. Managed to squeeze in 71 Lt.......which worked out to 10.9 Lt per 100 Klm's.

Not too bad given that I towed in traffic for around 120 Klm's......and played with the 'WOW' pedal a bit too much [bigsmile1]

Heading off this morning for a 3 1/2 hour trip, mainly freeway, so will be interesting to check the economy after the trip.

Cheers, Craig

[Disco4SE]

Did the 3.5 hour + freeway trip yesterday, which involved a bit of twisty country road driving through the Ottway's.

Ended up doing a total of 466 Klm's with an average (according to the trip computer) of 7.8 Lt per 100 Klm's. That is amazing........if its correct.

Welcome back to LR ownership Craig. You've done it in style! How does it feel to be back in one again after the Jeep (IIRC you moved from the D4 to a Cherokee)?

Hi Sean,
Ended up selling the D4 because of a surging problem that no one could fix.
Went to the Grand Cherokee which has been a great vehicle to be honest, but definitely not Range Rover comfort and quality.

Cheers, Craig

The fault is a design fault with the SVD 8 Turbo as it turns out. The oil supply will leak into the Turbo control unit causing fault codes and in my case chucking a DPF failure code. Car was flatbed to dealer in Tamworth. Search turned up this has caused a design change to the turbo oil feed , although LR only fix if failure occurs by the look of it. This will be the third turbo fitted to my car , and lucky it happened under warranty. Downside is there are no parts so car off the road for 6 weeks. I hope they add six weeks to my new car warranty ? Any SDV 8 owners might be warned and ask for the fix before the car s out of warranty as it is an expensive exercise.
