Thread: Disco TDI Manual v Auto

  1. #1
    Rooey Guest
    G'day folks,
    This is first my post on this site and I must say after trawling through the net looking for Landrover related information, this is the bible.
    Anyway, I'm presently in the market for a '96 to '98 Disco 2.5 tdi. As a lot of my driving will be offroad, I favour a manual. They must be popular because there's not a great number for sale in that year range.
    My question is, Manual or Auto? Can any of you who have been there and done that tell me how the auto compares with the manual and if it matches up.
    Looking forward to your comments
    Rooey

    OH GOD!!

    If I'm not mistaken this thread is going to turn into an all out argument by the pro-autobox race! Go for whatever you prefer, both are great.

    People say that the Manuals have more turbocharger lag, well I thinks its the opposite, oh yeah and Land Rover statistics favour the manual on top speed, economy and 0-100 time.

    Autos were way more popular, thats why there are more for sale.

    I have driven both extensively, and for both on and offroad prefer the auto

    Where did you get that info from? My handbook says the exact opposite to what you just said, at least as far as fuel consumption goes, and its been my experience that the auto was quicker to 100, top speed about the same (and a friend and I tested by drag racing our discos several times - on a private road through a dairy farm).

    Thats not really a fair test. I got my figures from the genuine workshop manual for the 1994 MY and the owners manual for the 1994 MY. I can go out and dig them up and post the actual figures.

    I suppose it all depends on what you prefer, I do a lot of country kms and provided the road is flat (or slightly downhill) I prefer to shift into the highest possible gear and maintain speed using ~1800 revs. It will satisfactorily maintain 80 using the least throttle. If the road rises however, dropping down a gear (or two) gives best economy. Obviously with the auto this goal is unattainable and it will always be revving.

    ok here we go a auto will keep you in the boost when accelerating cause you dont take your foot off the go pedal to change gears

    a manual you take your foot off to change gears one bad point for manual turbo diesels

    next is the important part as you state you will be off road a bit , i own a Tdi manual

    the manual is far better for engine braking where as a auto WILL run away on a down hill run not good for a slippery hill cause you will need to keep the speed down with the middle pedal (brakes) WHICH IS DANGEROUS

    thats my 2$ worth

    but there will be plenty of knockers that will try and debunk my understanding dont worry

    if you change gears truck driver style, sort of simulating the effect of an autobox you can minimise the lag, but yes I grant that autos probably have the edge there. I have had reports from a neighbour with a Tdi Auto of chronic turbo lag, especially when towing.

    rangieman, I agree with what you are saying "in its entirety".

    I find that taking of at lights, planting the foot reveals chronic lag, but from 1-2, 2-3 etc, if you "feather" the throttle the lag isnt so bad.
