    Default Prado 150: 4.0 Petrol vs 2.8 Diesel

    Some interesting facts. With the release of the latest Prado 2.8 diesel, I was looking forward to see how it will perform with the 500N.m of torque. However, I was disappointed to see that the “old school” 4.0 still outperforms it (except at the fuel station). I expected that the 0-100km/h would still favour the petrol, but was really surprised to see the acceleration (where torque will come into play) from 80 -100 – 120 still favours the petrol model. The comparison results below is from Car Magazine's actual test results.

    You'll probably need to rev the tits off the V6 to get those figures (relative to the diesel)...

    LOL - fortunately the 4.0 is very happy at "revving"

    And what makes you think that torque isn't a factor in the 0-100 km/h acceleration (yes, that's acceleration, too)?

    It's the torque curves that you need to compare.
    And since both models seem to incorporate the same 6 speed gearbox, the 2.8 TD can't really take advantage of it's higher torque. Maybe a 10 speed gearbox would change that.

    The 4.0L tested was still the 5 speed.....

    That is more or less what was said about the new 150 kW Fortuner as well. The power and torque looks good on paper but does not make much of a difference when on road performance is compared to that of the 130 kW Fortuner.

    People forget that 300Nm in 3rd is more powerful than 400Nm in 5th

    Like a long lever and a short lever.. with the same arm...

    You can have more torque but because your diesel cannot rev it needs a longer gear.. removing the torque benefit

    Not enough difference to allow the TD to stay in it's optimum torque band. You would need A LOT more gears than the petrol V6 in order to allow this to happen, maybe 8 or better 10 and a very fast shifting box.

    Ladies and Gentlemen, my simple thought is, if you have deep, very deep, pockets and no issue with fuel consumption then go for the petrol guzzler and if fuel consumption is a big factor for you then go for the 2.8 diesel.
    I have the 2.8 and not looking for a racer… hello, it’s not meant for that.
    The 2.8 is absolutely magnificent for what I need and want.

    I'm no expert, but I think Petrol vs Diesel figures on paper can be VERY different to real world driving.

    That 2,8 Diesel is a beast IRO Torque, and I havent driven it but I'm 99.99 % sure the 2,8 will outperform the Petrol in slow rock crawl work AND towing at 100/110 by quite a margin.

    Top speed/0-100 etc etc, yes - I agree - the Petrol. But thats not what you need a Prado (or any 4x4 for that matter) for.

    At really low rpm the petrol will make more torque , because the diesel isn’t boosting yet.
    My old 4,0L Hilux has more ooomf off idle than my 3L diesel Touareg. But once the latter starts boosting it will leave the 4L for dead. So for really slow crawling 4x4 work I would back the petrol.

    Wil nie stry nie maar daai 2,8 maak vanaf idle BAIE torque.........ek het self een gehad vir lank, en met paar ander gery. Jy gaan nie sommer 'n 2,8 gestol kry nie

    Disagree slightly on the crawling Part.
    Having driven 2 x 30 d4d's and currently a 2.8GD6 these diesels crawl very nicely.
    I have done most of the terror trails in the GD6 and recently I have become more wise as to the use of Difflock vs traction control. I hardly use DL anymore.
    The GD6 has no turbo lag. Not off the mark and not even if u kick down.
    Off the mark, it runs away from the V6 petrols. Yes agreed, top end the petrol is a winner.
    But crawling, well unless you have a FJ with A track. The GD6 is a fantastic performer.
    The only thing I am now considering is a DTE tuned pedal booster. It turns that GD6 into a monster.
