Effect of G4 accessories on MPG?

Group: Forum Member Posts: 46, Visits: 163	I am in the process of purchasing a G4 RR Sport (4.4 V8) and was just wondering what sort of effect the G4 items like the snorkel, roof rack and M/TR tyres have on fuel economy? Without the spot lights and plaque the roof rack looks quite streamlined to be honest. However I imagine the tyres will cause a lot of extra drag. Does the snorkel have any effect? Just be interested to know - cheers!

Also my d3 is for sale if you want something a bit more practical than a RRS. I have always fancied getting a g4 RRS but put off by the size of the boot...

I have always fancied getting a g4 RRS but put off by the size of the boot... Mark Thanks Mark! I don't really need the extra boot space or 7 seats, hence going for a Sport. My brother is considering a D3 though, how much is yours up for? Is it a V8 or TDV? davezrx (5/2/2012) BUT WHY BUY A G4 AND THEN TAKE ALL KIT OFF !!!!! sorry to moan but dont understand why people buy a G4 landrover then destroy it by taking kit off !!! As I said.... Mike_C (5/2/2012) Just be interested to know - cheers! ....not stripping it all off, I was just intrigued to know! The winch, ladder and snorkel will definitely stay on permanently. The car has two sets of wheels, originals with M/TR tyres and a second set with road tyres - the latter will be on the car most of the time, the G4 wheels/tyres will be fitted for greenlaning, my trip to Morocco, shows, etc. The roofrack I'm undecided but will probably keep it on most of the time, perhaps without the spotlights though as the roofrack itself looks relatively streamlined!! Out of interest, can you still get the M/TR tyres and if so, where from? The ones on thr original wheels are pretty worn unfortunately.

Roofracks tend to increase consumption by 10-12%, off road tyres by 10-20%. So with these figures you would possibly get around 14-15mpg average with all the kit on depending of course on how you drive it. Removing all the kit will only give you the 19mpg average anyway. If you remove all the kit and then drive quicker because it is lighter and handles better, you will save nothing. At todays average petrol price £1.41 / Litre miles/ mpg Cost 10000 15 £4276 Fully kitted 10000 18 £3563 Tyres/ wheels swapped only 10000 19 £3376 No Kit Difference Max £900 = £2.47 / day Possibly best to swap wheels as and when required. You also do not need to store a large roofrack and all the other kitand then have to refit when you want to attend a show Please note these figures are approximate and will vary with driving type and style.

I know I don't have the "works" roof rack but still have a big roof box. On BFG AT's with the box on it'll get 29mpg round the Lakes but with the box off low 30's are possible. It does have a GKN overdrive though. Compared to other td5's it seems quite frugal. Even with trailer/trialer being towed which is about 2.2ton being pulled it still manages 25mpg on a long run. Progress is glacial compared to my wifes Puma 90 but the 90 on road tyres can still barely manage 31mpg.
