Some PC towing fuel figures

[Apollo]

Had the chance to review the fuel usage of my PC (manual, chipped, standard setup except nudge bar and lights with 10000kms) towing a 6m x 2.5m x 1400kg-1500kg boat. Boat is wide and long but really only has a windscreen higher than the PC. Both trip fuel calcs done by fuel used v km travelled. First trip was hilly country travelling 80-100km/hr returning 10.8l/100kms and the second trip was flatter, so 90-100km/hr returning 9.8L/100km. Pretty happy with that. Interestingly, the fuel usage figure from the on board was pretty close (0.1-0.3L/100km) to actual. I havent put the GPS against the indicated speed so that might effect the above figures (5-10%?).

Will be interesting to play with different settings on the chip tuner to see if the fuel usages changes.

Those figures are similar to mine with the factory size tyres on. With the larger ones it increases by 0.9 lt/100.
I run a Steinbauer and when towing turn it up a notch. Does not effect fuel much at all, just helps with the hills and holding cruise. Camper weighs approx 1850kg when on a trip.

great figures ... show's Chips/Tunes/Remaps are doing their thing

manuals seem to be out doing the automatic transmissions by a great margin ...

would be interesting to seem some members put up their Auto figures also

8.0L/100km ; 1200km round trip (x4 Adults) ; 100-110km/h (Gps) ; loaded for glamping (cabin on the lake) ...

12 ltrs / 100klms average towing a 1900kg fully loaded Jayco 16ft 6 poptop single axle caravan.
Down to 11 on flat roads no wind , worst ever recorded was 16.5 in hilly country and high winds
Challenger is stock standard Base model Auto with Original Bridgestone tyres.

16L/100KM towing a camper on Fraser Island. Highway was around 12L/100KM

I have my ECU tuned

Auto or manual?

I have averaged 14.0 ~ 14.5 l/100 towing my soft floor offroad camper (1200kg) with the current vehicle since 2013. The Challenger is manual, mechanically standard, has a factory alloy bullbar and 3 roofbars on the top, with 265/70R17 A/T's and the camper also has A/T tyres. I travel at the posted speed limit, so often touring at 110km/h.

Having owned and towed the same camper for some 12 years with various vehicles I checked to see how the Challenger compared with previous cars. It's interesting: on average, NM Pajero 2.8 Diesel M/T 14 ~ 14.5, NS Pajero 3.2DID Auto 13.5 ~14.0, wife's 380 M/T 13 ~ 13.5 and wife's Outlander 2.4 M/T 13.5 ~ 14.0. Given the consistency, I don't worry about the economy so much but do keep a record just for interest.

Don't be offended by when I say that I am amazed by the number of posts where people think that 12.5 to15 litres per hundred is a great towing figure. I previously owned a manual Amarok 120kw 400NM, that consistently towed my 1000kg camper and returned 10 to 11 l/100km. I am still coming to terms with the reality that my PS will probably never achieve those figures.

Shit, I'm struggling to get 12.5L/100 with the Challenger daily on 33" MTs (Manual, winch, bar work, drawers/fridge/stereo, roof basket @ 2400kg inc driver), nevermind towing.

Exhaust, chip, cooler:





Admittedly the odo is atleast 7% out so an average of 12.7L/100 (with the 33s) goes down to 11.8L/100.

All good and interesting figures

[Flatbiskit]

WOW I would love to get some of the quoted figures.

As I have stated in other posts, I am getting around 19-20L/100Km when towing my Jayco swan outback.

I am coming to terms with these figures as normal as I have probably done to much to the car. On the plus side it has an ECU tune and there is a 3" exhaust in the near future.

On the down side, 2" lift, steel bull bar with winch, roof basket,(which is loaded with bikes when traveling) 32" tyres, Rear draws, and a family of 4.

The van is about 1,800kg when loaded.

It is better with the tune than before and has a lot more torque which helps. I know the lift and tyres added almost 2L/100Km.

Would I cahnge the car if i had the chance? Probably not I have a mate with a stock 200 series towing a 2t van getting similar figures to me so not much to gain and has no extras.

Just to add some more data to this thread. 4000km (at or below speed limits) trip at full camping mode, so 3.6t PC (2.5t) + camper (1100kg), 265/75/16 muddies on car and camper, 2" lift, roof racks/awning, nudge bar, manual, chipped, ECR block over a mixed terrain of highway 2500km, corrugation/BDust dirt roads 800km, very hilly mixed roads 500km, 4wd mix of 4H & 4L 200km. Total average fuel used for trip 12.5L/100kms. Got a Cape trip in 3 months, so will be interested in the numbers for that.

My auto PB 2012 has given me high 9kpl to low 10kpl in standard trim . Now with BFG All-terrain tyres ARB bullbar and winch drivinglights towbar roofracks side awning longrange fueltank ETC> fuel consumpsion has increased to around mid 11kpl. Went on a 8500kl trip from the northcoast down through SYDNEY to Wagga Port Augusta Ayres rock Kings canyon West and East Macdonald ranges Alice Springs Three Wayes and back to the north coast of N.S.W towing a Cub off-road trailer. Fitted a three inch exhaust before we left .. Averaged 14.6 for the trip <best was12. 6 and worst was 15.8 >. Since then we have an 18ft jaco outback and had three trips with consumpsion fighures of 16.8kpl to 17.4kpl on highway at highway speeds were possible....Car has 73500kl on the clock.....

All the drag from what’s loaded on the roof would add a couple of litres a hundred
