Wind Resistance increases to the square of the increase in speed, so if you double your speed, you quadruple the wind resistance. There is a huge difference in wind resistance between 90km/h and 110km/h, especially in a 4WD with lots of things hanging off it.

Spot on buddy, a rule of thumb i use is 10%, you make the surface area of your vehicle bigger by 10% you increase fuel usage by 10%. For me i use this 10% and lower my speed accordingly. If im fully loaded for a week trip i never ever (except for downhill and following someone) go over 90km. When loaded the fuel difference as you mentioned between 90 and 100km/h is huge. In a convoy change the leader every 50kms or so. Use the leaders drag wisely.

Cruise Control makes a noticeable negative effect on Fuel Economy on a 2.6tonne 100 series. Especially in hilly terrain. You can be far more economical by peddling it. As Ronny said, and i have to concur, the cruise control will maintain the speed no matter what, if that means stuffing 15psi of boost in and ramping up the injector duration and pump pressure, then it will. Driving it with your eyes and feet, can let the gas roll off as you crest a rise, because you know the downhill is coming....

I think the reason it helps me is that it maintains a more consistent speed. My speed doesn't slowly creep up whilst other cars are passing me. Keeping a steady speed means that my average is the same but the peaks are lower. I do turn it off when going down long hills (it doesn't perform well at very low power inputs) and when I'm getting to the top of a hill to stop me from flying over the top. I also pay attention to make sure it's in the right gear, but 6th gear at motorway speeds is about 2200 RPM so not exactly labouring!

The bit about downshifting to climb a hill depends a lot on what sort of engine we’re looking at, NA gas engines typically are at their most thermodynamically efficient at low RPMs (above idle!) with a wide open throttle. Things get more complicated when you add forced induction, gas engines need to richen up to avoid detonation, diesels often need to richen to keep the turbo from overheating.

Great tips, and couldn't be more right. Speed has the biggest impact on fuel economy since drag goes up as the square of velocity. An increase in speed from 90k/hr to 110k/hr is a 50% increase in the amount of drag. Couple of other tips: On vehicles that have locking hubs, unlocking them in 2wd if you won't be needing 4wd will help. Oil weight can make a difference in the internal friction of the engine - use what the manufacturer recommends for your temperature. if you are in colder temperatures, changing to the lower weight oil can help with economy. Also, if you have a petrol car, replacing a faulty o2 sensor can make a big difference as well.

I tend to disagree. CC in hilly country increases fuel consumption because it fails to ‘anticipate’ what’s ahead. In hilly terrain, it activates the brakes on downhills then doesn’t “see” the next hill coming and so brakes your speed back and then accelerates hard when it hits that next hill. In WA once you hit the flat country ie east of Dalwallinu / Wubin or north of Cervantes then you start to hit the flat country and yes then CC works. But I keep it off and manage the speed, braking and acceleration up to that point. Although I actually enjoy driving the car myself so only use the CC option for a little fatigue relief.

I got 2 toyota trucks 4runner (hilux surf 5VZFE) and a 100 series cruiser V8 gasoline. I replaced coil packs with all OEM and Denso TT spark plugs on cruiser and noticed an improvement in MPG. Currently at 230K miles and I get 7.11 Km per liter at 115 KmpH with cruise on. The rake at the rear end (rear end of the body 2-3 inches taller than the front: the factory setting) seems to improve the gas mileage as I experience with the 4runner. New sway bar bushings will also contribute to some MPG because it tries to keep the truck steady on the road helping to maintain good aerodynamic characteristics. I installed a bull bar on a hilux 106 diesel and right after that I noticed I cannot roll after a stop in the 2nd gear without revving the engine. Without the bullbar I can proceed from a stop in the 2nd gear at idle. OEM brake pads have contributed to an increase in MPG. OEM air filter will surely improve the MPG. I witnessed all these in my trucks and wanted to share it with others. These are in addition to what Ronny said. Please make more videos....

Lots of wide open spaces in between the rocky, fun bits. So I do what i can to conserve as much fuel for the off-roading parts of the journey by simply driving a bit slower. And yes, if you don't need the extra body armor, then don't put it on your vehicle. Simple enough advice, but you see a lot of people here in America doing just that.

On bitumen, imo, cruise control is brilliant as it greatly reduces fatigue over long distance. On gravel, I don't use cruise control as it becomes a safety issue (once again, imo) due to a potential loss of control. I've bought a diesel 4wd and it has a long range tank, I have a sedate driving style and I'm getting about 8-8.5 litres per 100km, and therefore about 1600km from the tank depending on load and driving conditions.

One thing often not considered is that rotational mass takes about three times more force to accelerate than static weight. For example, if you upgrade stock tyres to 35's you are easily adding 15 kg per wheel. This 60kg (15*4) rotational mass increase is therefore actually equivalent to having an extra 180kg on the vehicle

Ahoy Ronny, As the previous post explained, aerodynamic drag is, amongst other factors, proportional to frontal area, and the velocity squared! Frontal area, road friction and other factors add up of course, but not as much as higher velocity. Driving the desert tracks very slowly, velocity and frontal area have small impact, other factors drive your economy. Driving on bitumen highways at 110Km+ your velocity (& your frontal cross section) will drive your economy. Hope this helps. PS. The Drag coefficient also grows as you get to Mach 1, and them drops off again! Best to travel at much less than Mach 1, or over Mach 2, ideally at high altitude.

Another point..... if you're driving a turbo charged rig (gas or diesel), try to determine the RPM at which the turbo starts really going to work. Keep the RPMs below that and you will save a TON of fuel. On my 7.3L turbo diesel, 1850-1900 rpm and less consumes substantially less than 2000 plus rpm because at 2000 plus the turbo is stuffing enough air into the engine that the fuel system can stuff a whole lot more fuel into each cylinder full of air. Turbo's are great for power when you need it and for maintaining power as you climb into higher altitudes (by maintaining fuel air loading in the cylinder) but they can destroy fuel economy as well.

I've hear the 4x4 methodology presented differently. Both my grandfather and his father always said the 4wd system was made to get you out of trouble not into it, and that you only engage it for technical challenges, slippery terrain, hill climbs, etc. In my own experience, a graded gravel road doesn't require 4wd at all unless you want to drive fast, or drive in inclement weather. Outside of those cases the 4wd system has no impact at all on vehicle safety.

GREAT POINT on the chip tuning. It's a human nature issue. Those who are going to spend for a tune are the exact types (we're talking groups and stats here not any one individual) who are going to romp the fuel pedal, show off, etc. and undermine any fuel savings. The roof tent and/or gobs of gear on a rack WILL kill fuel economy when at speed but when off road at slower speeds (where wind resistance is minimized) it is less of a concern. Wind resistance is a logarithmic function of speed (i.e. resistance increases exponentially -- more per MPH with each increase in MPH).....NOTE: so is the kinetic energy you will experience in a crash so lower speeds are exponentially safer..... This physics limitation completely explains your final point about speed and fuel economy as well as the big chunks in the wind portions. Wind resistance increases exponentially with speed. Tire size. With bigger tires and wheels you increase friction but you also increase "rotational mass". An engineering term used to calculate how much inertia must be overcome to change the rotational speed. The higher the rotational mass the more energy (i.e. fuel) is required to make it start turning or turn faster (accelerate) as well as requiring more energy dissipation (i.e. brake heat/wear) to reduce rotational speed. While the braking issue doesn't decrease fuel economy, the increased energy required to overcome the increased rotation mass does affect fuel economy. AND as an added bonus, taller tires present a larger aerodynamic "plate" to further help reduce fuel economy. Just some thoughts from a retired US Marine, mechanic, pilot, and physics bum
@tlw88864 жыл бұрын
That's an unfortunate generalization on people who tune their vehicles. I'll admit that we have some dorks over here in the US that love to turn their Rams, Silverado's and "F" series trucks just to pour coal out the pipes, but those of us who use the tune to improve the power, torque and throttle response know the value of a proper ECM/TCM tune to get much more out of the engine without harming it or the environment. And that saves fuel and makes the vehicle better for off-road and towing conditions. I'm running a Colorado with the 2.8L dmax and the tune transformed the truck into a pleasure to drive and enhanced the off road performance by an order of magnitude.

On a long flat run I use my GQ Patrol's hand throttle as the cruise control. Set it at 90km/h on the flat, if it varies a little that's ok. If you hit a big hill, put the foot on the throttle. Only bad thing is you need to remember to disengage the hand throttle before slowing down or changing gears. Agree with the 90km/h. Car drives nicer, much more relaxed. Doesn't jump around so much with the 4" lift, less tiring. There's no race, just wind up the music. And getting down around 10L/100km with 10psi on a TD42 puts a smile on the face.. It just purrs.

I am just screwed all around. 2.8 gas (petrol) in a Jeep Cherokee XJ with 4.56 gears and no OD. Engine is WAY too small, and it gets a whopping 10 MPG, (23.5 l/100km). However, it won't use a full tank during a full weekend of off roading.

Good tips, only thing I might disagree with is the cruise control. We have an Outlander (SUV, not a true 4x4) and tow our 1t camper with it. The car has a CVT gearbox and combined with cruise control is awesome on the highway. We normally go at around 90 - 95km/h as that is the best in terms of efficiency for our car and the weight we are pulling. The cruise control in the Outlander will drop the speed a bit up hill before it engages the throttle and will just let the car coast down the hills. The dash gives me a live readout of the fuel consumption which is a great. I normally have that displaying the whole time so I can monitor it. Up some hills I will choose to disengage it and drop the speed to save fuel.

Do not use compressed air to clean air filters. Wash them. Above 80 km/h leave your windows closed and use the air cond. If towing, know what revs are best. Top gear might not be best ecconomy.

I agree with most of what you say, except I have found driving to revs rather than speed gives me best economy, I have a Pajero NT 2011, when towing a heavy trailer I try as hard as possible to drive at about 1900 revs and although this can be frustrating at times mostly I find I am doing speeds in excess of 90 klm often over 100, however the caveat on that is of course a head wind :-). I have a lot of gear on board and a lot of weight towing and on average 6.5 klm to ltr. roof rack 4 jerry cans not always full of fuel max tracks winch roobar metal rear bumper draws and using the under seat storage for gear as well, spare tyre not a rim, 116 ltr of water inside rear seats removed snorkel catch can chip tuned to economy. Anyway just my two bobs worth :-)

Don't need a bigger engine to tow I think. My 130 Td5 with a 2.5 litre 5 cylinder diesel will probably use less fuel than a V8 cruiser while towing, or in any other application. I once towed a smaller trailer with my 4.2 petrol V8 Range Rover classic auto and got 13 litres per 100km on a 500 kilometre trip and that was with a Defender roof strapped to some roof bars as well! The speed was never higher than 80 km/h as it is the speed limit while towing in Sweden. That makes for safe and fuel efficient towing!

When you say Cruise Control do you mean on or off road. I know that when I started using my cruise control on road the fuel saving was quite considerable. I know people will say that's a driver issue but I want to concentrate on other things when I drive like avoiding idiots. As far as using CC off road, well I simply don't use it.

1 thing you didn't add was the correct diff ratio it is totally when you tow something oppose to just having the weight in the back.. as for bar work i believe in full exoskeleton roll cages for my vehicles because it is 1 of the biggest safety features you can as from the late 80's to early 90's vehicle manufacturers to save weight started to aluminium as the building constract as such taking the texile strength out of the vehicles as such vehicles of today generally don't last in a roll over.. this option also gives you a recovery point you can attach too.. most nomads that I come across have stuff all clue on how to tow or pack a caravan let alone what their legal speed limit is given the weight they are towing... Especially if there prime towing experience is a 6x4 trailer full of garden waste... tail and head winds do effect fuel economy I suspect with the addition of DEF on vehicles you likely waste more fuel wh its use.. the original spec for land cruisers in the early to mid 80's was 5 ton, average weight today is 2.5-3 ton back then you had 3 engine options availacle v6 petrol, straight 6 diesel or v8 diesel and turbos or super chargers were the added optionals.. though you would usually opt for diesel because it had an engine break system.. with 13 tons on the road between caravan and vehicle you needed that stopping power in the cruiser.. this weight basis is based on towing a 30-45 foot caravan my opinion on petrol 4x4's soccer parent or work site type application looking the part though not really designed for true off road use..

@BenMitro6 жыл бұрын
Ronny, what about narrower tyres & rims? Not smaller diameter - narrower. They provide a lower wind cross section as well as lower rolling resistance. Andrew St Pierre White swears by them. Keeping all things equal, when you look at the cross section of mud or all terrain tyres the bit in the middle doesn't do much in terms of clearing the tyre of mud or water - if anything it gets in the way and slows the process down. In sand, the overall foot print is enhanced by wider tyres, but more so by larger diameter tyre.
