D-max 2.5 Fuel Consumption
Elder Raman
I know that the pure economy runs that have been done here and in Asia don't reflect the normal driving done by most drivers. but I would think that the vehicle would get at least the combined cycle of 8.2 lph for a drive on the highway at 2100 rpm at 100 kph.
Yer Hi , i have a colorado diesel auto and im getting 9.9ltrs/100k but ive only done 600k's but im rapped that is under 10 . Ive just dumped my patrol 2005 3ltr which at best got 13ltrs/100k and normally 15ltrs so yer im very happy with consumption and that i dont have deal with bloody nissan any more (ripoffs)
I have a scangauge in my jackaroo and what it does is reads some data from the car computer. For instance water temp, tps position, rpm, speed, fuel usage, and lots of others. Try google scangauge. By watching the fuel useage I have adjusted my style of driving a little to get better fuel economy.
My Dmax sits on 9.4l/100km around town but anything over 100kph really sucks the fuel - just like driving a brick into the wind. Offroad I get around 13/100km (lots of low range and idling). I'm not a heavy foot driver but I don't drive with economy in mind.
Towed my Jayco Basestation for the first time last week. 2000km. Best fuel economy was 16.9 l/100km and worst was 18.9 l/100km. Kept the boot into it all the time to maintain speed limit as best I could. Van was approximately 2.7Ton and the ute 2 adults and 3 kids with luggage in the tray.
I had one on for about 600kms and I was so disapointed with it's performance I ended up cutting it off in my driveway just to be rid of it. Straight thru pipe now and all is good again and the noise level has not change.
We picked up a Dmax SLM manual dual cab 4wd a couple of weeks ago. We have only done about 600km in it to date. This was made up of city suburban driving and one trip up to the sunshine coast and a few runs to the dump towing just a small 6x4 trailer.
The trip meter is showing average fuel consumption as 7.6L - 100km it did drop as low as 7.2L when we were on the open road.My driving style isn't aggressive just go with the flow of traffic. I tend to try and use the torque of the engine to my advantage by shifting early especially around the city.I did note that the speedo is a little optimistic when comparing it to GPS speed 100kmh on the car is about 96kmh on the gps. This is typical of most new cars about 4% error. So even corrected for this the consumption is 7.9L.
7.2LPH out of my colorado manual, the trick is not to go above 80kph, i take it you don't have the trip computer which shows you instant consumption because you find that in lower gears below 60 you use high consumption and above 80kph you start using more fuel just to keep cruising.
I do Have the trip computer that's shows instantaneous fuel consumption.7.2L 100km sounds about right for a manual.Really its just a matter of not using the accelerator to much. I guess what I was try to say for the guy in the first post if its his 1st TD is if you can shift up a gear to increase your speed rather than rev the engine more in the same gear your going to use less fuel. Something that isn't always possible to the same degree with petrol engines. A auto trans rules it out to.
I would have to agree that any 4wd with its large frontal area is going to be less efficient at high speeds due to the wind resistance. That said no one is going to drive on open roads at 80kmh. At 100kmh no load I am sure you can get in the low 7s in a manual and at 110km I am guessing hi 7s.
I am only on my 2nd tank of fuel now and so far the average consumption is 7.4L 100km on this tank and its been all city driving.We just had a canopy fitted this week so not sure if that will make things better or worse on the open road.
80 will drive me nuts and any one behind him. we dont need any more daudlers on the road the road rage is giving me blood presure lol besides if you do 20 under the limit for no reason other than fuel economy you will and should get a ticket for obstructing trafic
after 15ooo kms on the clock fuel economy is between 9 and 10 depending on wind direction doing 100 by the gps not the inacurate speedo in a 2010 colorado crew cab diesel automatic with the cruze off.
if you drive at 100 clicks by the speedo the fuel economy drops to 8-9 ltrs per 100 , that 5kms of error costs 10% more , its the cheapest way manufactures can make you beleive your getting a cheaper car to run and make you beleive its got more grunt than the car with the acurate speedo you used to have, personaly i think it should be law that manufactures get the speedo with in 1% when new (as tyres wear the driver goes slower). think how many lives would be saved, half of us drive by gps speed , half drive by inacurate speedo from new then tyres wear and drivers go slower so to many cars get overtaken and too many are on the wrong side of the road.
i cant confirm this but a truck driver told me he got stuck behind that dmax on the last fuel tank run from out west of brisbane with the boat, he was doing less tan 50kms per hour presumingly in fifth gear as it was rattling its but off.
I still think think its one of if not the most frugal 4wd duel cab from what we have to pick from in 2010. I think if its 7.1 or 7.5 or even 8L 100km that you return on the open road, its all very good. And I don't think any other manufacturer will sell you anything comparable the same that consumes less.
i agree that the speedo should be acurate. my mate bought a ford ranger. he reckons his speedo reads 112km when his GPS reads 100km. ford reckon that it is within specs. he then asked if he has a 100,000km warranty or a 112,000km warranty. guess what the answer was. i would be filthy if i had a major failure with 105,000km on the odometre.
In order to showcase the fuel efficiency of its new 1.9l turbo diesel D-Max bakkie range Isuzu has completed a test drive from Johannesburg to Cape Town. Behind the wheel was Grant McCleery, head of the Isuzu Driving Academy and former racing driver.
He drove a D-Max 1.9 Ddi Double Cab 4x2 manual. Over the 1,431km journey McCleery managed to only use 73.82l of fuel, translating to an impressive 5.1l/100km consumption. Additionally, he maintained an average speed of 100km/h over the distance.
Isuzu's D-Max models have a long history of reliability and excellent fuel economy. Isuzu Motors SA's goal was to highlight the budget-friendly capabilities of its D-Max bakkie range in response to the high fuel prices in South Africa.
The new 1.9l four-cylinder intercooled turbo diesel produces 110kW of power and 350Nm of torque. It has a 200 MPA common rail direct injection system and a high-efficiency variable geometry turbocharger that delivers excellent response and acceleration.
Built in Struandale, Gqeberha, this seventh-generation D-Max went on sale in 2022. No less than 24 D-Max models are on offer in South Africa, 16 of which powered by the 1.9 Ddi engine, including five Single Cabs, four Extended Cabs, and five Double Cabs.
Extensive upgrades were implemented for the proven range-topping 3.0 Ddi engine to improve performance and economy. To further enhance the product line up Isuzu also introduced the latest-generation 1.9-litre four-cylinder intercooled turbodiesel engine that has had a significant leap forward on fuel efficiency.
ISUZU offers an extensive line-up of 24 D-MAX models in South Africa, 16 of which are powered by the economical 1.9 Ddi engine. There are five Single Cabs, four Extended Cabs, and five Double Cabs available in the 1.9 Ddi engine range.
The RZ4E-TC 1.9-litre four-cylinder intercooled turbodiesel engine used in the D-MAX range relies on a 200 MPa common rail direct injection system along with a high-efficiency variable geometry turbocharger with an electronically controlled actuator to deliver excellent turbo response and acceleration across the engine speed range. As a result, it produces higher outputs than many larger-capacity engines with 110 kW of power at 3 600 r/min, and peak torque of 350 Nm between 1 800 and 2 600 r/min.
Fuel consumption is optimised by utilising a unique combustion chamber design, precise fuel injection control with DLC (Diamond-Like-Carbon) coated fuel injector needles, a low-friction alternator and an improved exhaust system with an EGR (exhaust gas recirculation) cooler. Noise and vibration are reduced, thanks to the high-stiffness cylinder block and a resin camshaft cover.
