    Do all 110s understeer?

    Or just 3.9's?

    All the 4BD1 powered 110s I have owned/driven have a tendency to understeer when pushed hard (especially on wet roads). I have assumed this is due to the big heavy engine up front.

    I have driven a few tdis, and a V8 county - but haven't ever wanted to push a borrowed vehicle hard enough to find out. So do they all do it?

    in my experience, yes some not as bad as others and it gets worse if you drive with the difflock in...

    that said oversteer can be induced if you want it.

    not just 3.9s I would think,,
    (from a control point of view) constant 4wds have the inherint(RON!!!) problem--you are never sure where exactly the power is going. front?? back??

    add some unintended weight up the front,,,,

    its the formula for changing direction of mass,,


    LR's tend to lack the power/energy bit

    I know that well, when I am being silly on (deserted) wet roads I find it switches from under to over steer VERY quickly. The crappy falken AT tyres don't help though - worst tyres I have ever owned, wear quickly, AND have less grip than a mud terrain.

    Oversteer is when the passengers are scared, understeer is when the driver is scared.

    i'd guess that all understeer. it's a product of weight and speed versus change of direction.
    you are pushing near two tons into a corner
    there is a simple cure to the problem, if it is a problem,
    slow down.

    Are you saying constant 4WD has inherent understeer? My impression (as a fairly sedate driver) is that the Defender doesn't seem to understeer at all on loose gravel whereas the Series III understeered quite easily.
    I am thinking of quite slow speeds on very windy roads. Maybe things are different at speeds I don't want to get up to in the Defender and couldn't get up to in the Series III.

    while thats the correct solution the blue stripey has thus to say....

    Nahh, just dab the brakes on the way in to get the weight on the steers then noisey pedal it to the point of balance... you can race RWD falcons and commodores through rounda bouts like that, 3rds a good gear for it and you can do it at ohh 70-80kph without too much hassle.... Just gotta watch the tyre rotation tho, they tend to scallop the fronts a bit doing it...........

    thers a reason for that Its called live beam axles on spring leaves. The series suspension was never ment for fast handling and the springs have the reaction time of a politician whose been ordered to sign his own pay cut authorisation forms.. When they get to cornering they lighten up considerabley on the inside and over force the outside edge which means no grip on the front.. The problem is further exasperated by the rotational mass, unsprung mass at the front end and the fact that the fronts run a higher pressure to make it easier to turn on road pressure tyres....

    Blue stripey says this....

    its just the lack of powersteering to let you flick the front round and the lack of power to get the tail to step out.....

    its why race cars are mid-engined,,

    yes, in the end all front engined cars understeer.

    Wasn't the car with the most chronic terminal understeer ever the Hillman Imp from the 1960s?
    It had a rear engine, but with nothing in the (front) boot, on a wet road the front wheels had no grip at all.
    So there is more to it than where you put the engine, although mid-engine probably make it a lot easier to get it right.

    Pedro, you should have said "real race cars are...."



    Actually they are mid engined for better traction, without the evil handling trade-off you get with dak daks and their bigger rear engined cousins from Zuffenhausen.
    The little buggers still understeer too, to greater and lesser degrees. Oversteer is generally driver induced, unless you have something evil like the above mentioned rear engined abominations, or an open wheeler where the designer in his infinite wisdom has the front roll centre higher than the rear and the transition from 'balanced' to 'terminal oversteer' happens in a nano-second at 215km/h.
