Thread: Fuel Consumption - Towing TDV6 2.7

Different towing when compared to the D2 isn't it!

Quite different! I haven't bonded with it yet like I did the D2 but hopefully soon!

Took me a good few years to bond to mine....It is such a different animal.

In fact in some ways i still miss the D2a

I drove the 950 km from Canberra to Warrnambool to pick up a smaller campervan. On the way down I drove on one tank at around the speed limit and averaged 8.8l/100km (computer said 7.6).

On the way back towing the 600kg van (about 165cm tall and a bit wider than the RRS) I was doing about 10kph slower than the speed limits and averaged 13.45l/100km.

Now that in itself is very good fuel consumption for about 3.2tonnes train weight but it is over 50% worse fuel consumption compared to the unloaded state. Given the small size of the van I would have not expected fuel consumption to be so bad - I would hate to see what the consumption would have been had it been a full sized 2.5t caravan.

The scan gauge was showing up 65l/100km when going up some hills on the Hume but also when speeds reduced to around 80kph on the straights fuel consumption reduced to near normal levels - so aerodynamics are coming into plan which is surprising for a small camper.

So what sort of fuel consumption are others getting with their 2.7s when towing smaller campervans and larger campertrailers. With only 84l in the tank you start looking for fuel after only covering 400-450km.

very steep coming north to south, the d4 2.7 was down to 1st in high range, there's a massive reduction in gearing from 2 to 1st, near top the eng temp alarm went off at 104c, stopped with engine running, it cooled fast, trans alarm never went off
new tow 1.8 tonne single axle van, 700km fuel reading 12.7 l/100
roads are so bad that there was lots of pitching moments on the rear axle, maybe I will shift some weight off of the ball, air suspension, 6 sp.auto, all in all a very exceptional tow vehicle

that's a lotta fuel

Something is wrong if its doing 16 not towing, unless its highly modded.

Ours empty, will do 10 or slightly less,all day, at an actual of 105Km/hr,by GPS.
Rooftop tent on, fully loaded, same speed around 12.5 to 13.0,depending on headwind.Similar to our old D4.Same mods as the D4.
Thats worked out actual, although the dash read out is deadly accurate, unlike our last D4,which was up to 40% out at times.

Speed makes a huge difference, particularly when towing, so any fuel usage on here without the speed as well, is a useless figure.
As is the dash readout on the earlier D4's,possibly the later ones were better.

driver of semis, with d4 i use command shift, that means i can shift to 6th gear when D mode stays in 5th, when speed droops Ishift to 5th, looking at the display this method uses less fuel
Driving heavy semis, shift by Pyro temp. I never drive my d4 in D mode

The lotta fuel comment was in reference to a TDV8 200 series not a D4.

My brother's 200 series did around 15l/100 around town not towing and well over 20l/100 when towing.

As was my post, with some comparisons to our previous D4.
