Thread: 2.2 Puma Defender Fuel Economy

I've done Pilbara/goldfields to Sydney 5 times in 5 years,let me know next time your going and we'll do the Talawana/Canning/Gary highway to Alice route,thats a nice drive. Pat

And because its bloody annoying and dangerous for everyone holding up traffic or being held up by people doing exactly that...

Impatience breeds frustration, which breeds poor decision making which leads to incidents. Frustrated motorists being some of the worst.

Learn to be patient. Impatience, not obeying speed limits or driving at respectable speeds, causes accidents. I said 100km/h, not 70km/h.

Despite what the do gooders tell you 16 hours at 100 Km/h is not safer than sitting on a speed that will keep you attentive.
I lived in the Territory for years when they had no speed limits I am no an advocate of running at excessive speed, most people seemed to settle at 120-130 Km/h.

I lived in some of the more remote parts of the NT for 8 years. My work took me all over the NT. It was nothing to drive from Alice out to the Qld border for a job and return the next day. I also spent two years in southern Cape York Peninsula. Does any of that count? Sure, I didn't always get around at 100km/h but it was only impatience that made me do it. I didn't need to, and I don't accept that it's safer not to.

We have had our 110 since 2010 and have travelled 34000 km in that time. We don't flog the car and have never had worse than 12.5/100km and that was towing a camper trailer. We usually get high 9s to low 10s/100kms. Doing a mixture of driving including off road trails.

Damned if I can find it... but there's a univ. report somewhere on the Net wherein students undertook a supervised engineering study on the effects of aerodynamic drag on fuel economy. They had a vehicle on a dyno in a wind tunnel.... also measured effects of aircon (~ 0.5 l/100km) open windows( 0.5-1l/100km), roof rack -empty (1-2 L/100km).

Apparently these aerodynamic effects become quite pronounced above 80kmh ...where the inverse square law really bites...double the drag =X4 the power needed to maintain the speed...

Apparently the rush to fit "supermarket trolly wheels" as spare tyres in modern cars is all part of the demand for lower emissions. A spare wheel (full size) is worth 0.2 -0.5L/100km in some marques

FYI!

cheers

My TDCi uses the same amount of fuel at 80 that it does at 110,450k's from a tank,I do 110.Interesting enough it still gets 450k's from a tank with the cub camper on the back,work that out. Pat

I would guess that the 'rush' to fit those weird spare wheels, or the current trend of no spare wheel at all, is mainly cost driven - ie it's cheaper not to fit one and still charge the same price. Bit like the Qantas olive scenario. Remember in the olden days cars used to come with tool kits and even tyre pumps - now you are lucky to even get a jack handle - and I suppose that with the new cars with no spare wheel, you won't even get that as you don't need one. Sure, the less weight will give you more mileage but what happens when you get a flat tyre?
