    Default GD6 2.4 vs 2.8 fuel consumption.

    Hi all, anyone with real life experience, consumption between the 2.4 and 2.8?

    Like for like, Fortuner vs Fortuner, SC vs SC, DC vs DC.

    I'm actually mostly interested in Fortuner auto 4x4, but I think any of the others should help color the picture.

    Thanks

    My wife has a fortuner 2.8 4x4, but the 2020 model. I doubt she gets much under 12l/100km. I have just procured a Hilux 2.8 4x4 and it is getting around 8.6. The main difference is obviously driving style. Both are autos.

    You will also need to distinguish between the 130 kW and 150 kW 2.8. The 150 kW is heavier on juice by a fair amount.

    My 2.8 Fortuner hovers at 11.5 - 11.8 l/100km purely city driving. But I don't drive like a granny, and the older I get the heavier my foot seem to get.

    Open road, cruising on speed control it easily goes down to below 7L/100. Not towing of course.

    thatís odd - I find the 150kw engine much the same on the high way and towing the boat about 1km/l better.

    Have you measured while towing on tar?

    If I recall the 150 kW should be lighter than the 120 kW according to Toyota specs whatever that's worth.
    I actually forgot about the 120 vs 150, in general how do you find the difference between the 2 in general daily driving and then towing?

    Going by the on board computer only, which is pretty accurate, it has never been above 13 as far as I can remember. On tar.

    Agreed, the 150KW is definitely more economical.

    Daily driving the 150kw is more energetic right through the rev range. The towing it also feels stronger even considering my previous was chipped with a pipe by KSD.

    The biggest difference I’ve found is the following:

    - Way better cooling, both FT and previous Hilux viscous fans would kick in on most uphills. (2.7 ton boat and trailer) my 150kw viscous prob has kicked in twice when towing the boat on a hot day on the same routes.

    - bigger turbo seems to give it more torque/power in the higher rpm. The fortuner and previous hilux both eventually chipped with a pipe always seemed to loose steam at 3500rpm up. My old lady has a stock 2.8 and after driving it yesterday for the first time in a while I’m taking it to ATN to be mapped.

    - then the gearbox. The lock up points are lower on the 150kw. The TC actually locks up compared to my previous hilux which would hardly ever get into 6th. Shifting points seem better and I would say this is likely the biggest difference between the two. Still - I would prefer the manual but the box is improved.

    if you have a google you will note there were Changes as I have found above.

    overall economy compared to chipped 2.8’s is much the same. All 3 of our 2.8’s get 8.5km/l up to 9.5km/l driven really well.

    the previous hilux would give around 5km/l towing the boat on the same route over 130km and the new one around 6km/l. Difference could be because of the gearbox, but I normally lock them in 4th the entire trip.

    I went back to a 2016 test of a 130 kW Fortuner Auto and compared it to a Feb 2021 test of a 150 kW Fortuner Auto by CAR magazine.

    Toyota claimed figure 2016: 7.6 L/100km
    Toyota claimed figure 2021: 8.9 L/100km

    Fuel route test 2016: 9.1 L/100km
    Fuel route test 2021: 11.1 L/100km

    So Toyota also agreed that the 150 kW is heavier on juice by 1.3 L/100km on the claimed figure. In real life it is even heavier by 2.1 L/100km in mixed driving on a controlled route.


    For interest sake the 2021 Fortuner was 0.7 seconds faster to 100 km/h and 0.8 seconds faster between 100 and 120 km/h.

    Just been driving with my wife in my new Hilux and I can see why we get massively different consumption. Her fortuna is a 2020 so 130kw and Mine is 150kw. If I drive mine, I am getting around 8.6l/100km. When she drives it it is more like 12.5l/100km.

    I think how you drive and how many things you do to the vehicle will make a bigger difference than the 2.4 vs 2.8. I am interested to see Bryanís impressions on towing a big boat. I have only towed mine on flat roads around dbn to the ski boat club and back so far. Next time I am down there, will probably try out umkomaas and see how it does on some rolling hills.

    I am sure it will have to work a lot harder.

    Comparing the fuel consumption of different Fortuners are like comparing facial hair on models

    yeah, I know a few guys who get better and worse than I get. My wife and drive much the same and 8.5km/l is what we average at. Both our vehicles do have bigger Tyres. 255/75R17 so Iím sure that makes me them a bit heavier juice.

    however Iím adamant even compared to tuned up only spec 2.8ís the new 150kw working hard is lighter on fuel and stronger towing than the 130kw.

    We have both the 2.4 Fortuner 4x4 and the new 2.8 Hilux 4x4. Town and surrounds driving mostly and consumption on on the 2.4 Fortuner is 9.4l /100km and the new Hilux 2.8 is 9.2l /100km. I can add that both of us do not have a heavy foot....

    Is that on the trip computer or calculated? My current Toyota is fairly accurate. The previous one was out by 3 km/L so on a tank it was out by 150 km. Hectic.

    Since you are towing a stuffing heavy boat (I had mine on the weigh bridge and it was 2150 with a fair amount of fuel) have you ever felt the need to add a gearbox cooler? I know this was considered a requirement back in the day for any towing automatic, but that was in the days before lockup clutches etc.

    Once I have my brake setup working nicely, I will be dragging the old girl around the neighbourhood (well at least to Umkomaas) and would like to know the Gearbox is up to it and I donít need to add an additional cooler.

    Yes, as per trip computer.
