    The New Defender: Diesel vs Petrol

    Interested in people’s views on the initial engine choices and what you would pick.

    Normally I would go for Diesel over Petrol any day but with diesels getting smaller and more complicated when it comes to emission controls I am not so sure these days. Would have been nice if they had included a 3L 6 cyl Diesel option from the start but maybe this will come later.

    As it is at present, the 3L petrol engine is looking like a great option.

    First time I have seen some fuel economy figures. So 24mpg is about 12l/100km? If so the P400 petrol is looking ok.

    Can you get 18” OEM rims to fit the vehicle with P400 petrol?

    Shows potential - but of course this assumes you are not racing everyone off the lights - which I imagine would be hard to avoid.

    WLTP testing limits acceleration to 1.6m/s2 - so 0-100kph takes 15.5s - so like being stuck in traffic behind a stock TD5 Disco!

    I agree though the P400 looks promising.

    Seems not - the P400 has larger brakes so the 18” OEM rims won’t fit - which is a negative in my mind as well.

    Naturally the most powerful motor is appealing but (& I'm thinking of a touring vehicle) does one need that much power & torque at the cost of a 20% reduction in available range?

    Having checked the configurator in Oz and UK the short answer is no it seems. Reason being rim and tyre size seems directly linked to engine capacity which is no great surprise. Nothing on the diesel 6 yet but expect the same is my view.

    Yes petrol 6 looks OK if you don't tow a lot nor drive a fully loaded car around all the time. IMHO the 4cyl diesel would be fine for general touring and the odd Simpson crossing etc. As well as fitting probably most people's needs for a daily drive as well. Whereas we travel 3-5 months each year towing our AOR camper (2500kg) so diesel 6 is what we are waiting for.

    We have specced what we want, less the diesel, and are waiting for indicative pricing to come back. I drove an LC200 VX yesterday just to refresh my memory and that experience keeps me on this side of the fence ATM

    Have to agree.... these diesels look a bit puny, same 430 NM as a Pajero Sport. From other reports, the P400 engine does not suffer any turbo lag either with the mild hybrid assisting from take off. Also with IP6x water proofing of all components and wading (float away) depth of 900mm, there appears to be no advantage to diesels of not having spark plugs etc. Just be prepared to pay a bit extra for the increased fuel use.
    I am wondering if service times will increase (for both diesel and petrol) if they have to remove water-proofing to get to components and then put it back again later?

    The D200 and P300 would have to be non-starters in my mind. I assume these are targeting fleet or company buyers and just to lower the starting price before you spec up to a higher level.

    Maybe aftermarket,if not, it won’t be in my driveway.
    Some say run a 20” and go oversize,to get more sidewall,but that’s not what I want to do.

    The diesels in my opinion are a bit lacking,the vehicle will be almost as heavy as my D4.

    And going by D5 reports,with same Diesel engine,fuel economy not fantastic.
    In fact it’s very similar to a late model D4,8apeed,with a heap less power and torque.

    The smaller diesel will probably not sell well and be dropped,as happened with D5.
