Fuel Economy Specs on New Ute

jizmo on 18/05/2022 - 18:42

Work Ute is getting a bit old and needed repairs are going to outweigh buying new maybe.
Anyway fuel economy on my old ute weight about 2.5 tonnes including around 1200KG of gear 2.7ltr diesel non turbo getting about 8.5L per 100KLM
New Nissan or Toyota Cab chassis 2.3/2.4Ltr turbo diesel state 7.2L per 100KLM empty unloaded.

Thought new car technology made them more fuel efficient. If added the extra 1200KG of trade tools on board would it be getting 6Ltr per 100KLM?

Should I patch the car up and wait for electric utes to come out

    I don't drive a ute, but 8.5L/100km sounds pretty good for something that big.
    What kind of mix of highway/city driving gets you the 8.5L/100km? There'll be a very big difference between the two.

    I'd expect increased load to have a large impact on city fuel consumption (extra fuel needed to accelerate the extra load), and a relatively small impact on highway fuel consumption (the extra load will only slightly increase the rolling resistance).

    If the official consumption figure for the new ute is 7.2L/100km, what is it for your old one?

      Tried finding out today but can't find the specs. I start and try to finish work early leave 5-5.30AM and mostly toll road highway use rarely see's any major traffic jams.

        The official consumption figure is for a mix of highway and city driving, and it's usually pretty optimistic. Most people will use quite a bit more in mixed driving.

        If you're mainly doing highway driving, you'll probably use a little less than the mixed consumption figure.

    A smaller L/100km number is better. Adding weight of tools will make the L/100km value higher.

      When unsure about which direction something will take a number in, I usually find it helpful to take it to the extreme.

      If adding 1200kg of tools makes the consumption go down by 1.2L/100km, then surely if you add more, it'll go down by even more, right? So if you add 7200kg of tools, then consumption will be zero. Whoops, that doesn't sound right… must be the wrong way round.

    there's no way in goddamn hell a two ton diesel ute loaded up with 1,200kg of tools is going to get 6lt/100km lol…

    the variety of 2-2.5 litre two ton diesel utes i would be cheering if i got sub <10/100km around town with a small load

      get 6lt/100km lol…

      Well .. downhill it will ;)

      • tonyjzx on 18/05/2022 - 19:36

        tbf it would probably get it on a freeway assuming its not lifted on 32s with bars and lights

        i used to get 6/7s in a v8 on a freeway so i guess a turbo diesel 2.0 w/ an 8 spd might do it

    • jizmo on 18/05/2022 - 20:03

      think last time I went to the dump the weigh bridge read 2.3/2.5 tonne. All tools on board only dumping a 50KG fridge.
      Total weight of my ute normally is 2.3-2.5 tonne loaded with tools.

    I barely get 6L/100KM in my 1.4L Suzuki Swift lol

    I’m guessing you have an old Navara. The new motors are much more fuel efficient as they put out about double the power and the Ute weighs about 500kg more, so actually using less fuel is a massive gain. I don’t think you will fin any ute that gets better than 7.2 in real world driving.

      the only difference OP will see is that any modern turbo diesel ute will pull the same and get the same ecomony but it wont be slow as hell like that old not turbo thing

      tbh if your old ute does 8.5 with a decent load and you can put up with the lack of speed then i'd be fine with it

      you'd be hard pressed to get 8.5 realistically with any modern ute when worked

      I’m guessing hilux. Don’t think Navara has had a 2.7l non turbo diesel.

      • jizmo on 19/05/2022 - 18:31

        They do TD2.7 That's my donkey Made in Japan. Don't think this motor will ever fail just everything around the car is.

        • spackbace on 19/05/2022 - 18:45

          Oof, pre-2000 nugget

        • Euphemistic on 19/05/2022 - 21:08

          Now I think of it, think the 2.7 hilux motor was a petrol.

    Your driving style makes a big difference. You might find you do better than the stated rating if you are getting 8.5 on an old model.

    I have a Pajero Sport (Triton Chassis and engine, different gearbox). 2.4L diesel / 8 speed auto

    I get 9.5l/100km on the highway at 100-110kph and 12-14L/100km around inner city Sydney doing short (<10km) trips. I don't think the other makes would be vastly different.

    Mitsubishi have already been proven in court to be liars about fuel economy.

    Mitsubishi quote
    Fuel Consumption Combined Official test cycle fuel use for combined fuel consumption 8 (L/100km)
    Fuel Consumption Extra Urban Official test cycle fuel consumption for country driving conditions. 7 (L/100km)
    Fuel Consumption Urban Official test cycle fuel consumption in city driving conditions 9.8 (L/100km)

    NB: I don't think any of the Navarra/HiLux/Triton/Ranger/BT50/Izuzu crowd are rated to carry 1200kg.

      OP, surely the 1200kg is in a trailer, right?

      • jizmo on 19/05/2022 - 18:18

        Dunno as I said on a weigh bridge is about 2.3-2.5T so just a guess. Put extra 2 leafs in the springs upgraded shockies ages ago. No Tow bar

          You might be overestimating the weight of the tools. If it is a 2001 Navara, the kerb weight is 1535kg, plus weight of driver means the tools are probably around 600-700kg. If they are 1200kg that would definitely exceed the maximum capacity.

        • brad1-8tsi on 20/05/2022 - 08:55

          jizmo.

          You can put as many extra leaves and heavy duty "shockies" in as you want but if you exceed the certified payload you are up the creek.

          I think the basic Single cab Hilux Workmate has a payload of 1200kg but that includes all accessories (the tray itself, towbar, occupants, etc).
