    Default Fuel Consumption and CO2 Emissions

    I have just been looking at the Toyota Zone magazine and am a bit confused as to the claims made by Toyota of the fuel consumption and CO2 emissions.
    The Fortuner 3,0 D-4D RB 4x2 manual and the Fortuner 3,0 D-4D 4x4 manual both have the exact same engines with the same power and the same torque ratings and yet the fuel consumption and CO2 emissions for the 4x2 are 12,7 and 303 respectively. The fuel consumption and CO2 emissions for the 4x4 are 8,6 and 228 respectively. I drive the 4x4 and the best fuel consumption that I have managed on a tank is 10,5. I have tried different driving styles but can't better my 10,5 l/100kms.
    Can somebody explain the different fuel consumptions and CO2 emissions between the 4x2(which is much higher) and the 4x4. What am I doing wrong that I can't get a better fuel consumption I know some of you will say that it is because it's a Toyota , but it's really not that.

    Durban has loads of hills, possibly why you can't get below 10.5? Coastal cars tend to use more fuel and this is not because of the increased power but increased air resistance. Remember the speed squared law.

    As for the 4x2 argument, are you SURE they have the same figures? With the Nissans they are different as the 4x2's are the "fleet" vehicles and are therefore detuned to be "african" proof.

    Thanks dieselfan but I found I was getting a better consumption with my 2007 Fortuner.

    The power and torque figures are shown as 120/3400 and 343/1400 respectively for the 4x2 and the 4x4 and yet the fuel consumption and CO2 emissions for the 4x2 are shown as much higher
