The consensus seems to be that auto's work well with big petrol engines. But at what point is an engine too small especially if it is an oil burner given their abundence of torque?

Dunno, but the 2.5l in the Discovery seems to work well with the ZF auto-box.

I agree, My sister has on and I've driven a couple of others.  The engine revs a bit more as you'd expect but if anything that makes it last longer as it's never slugging away.

As with any auto, expect higher fuel consumption, but I think the size of the car plus the size of the engine decides whether an auto box works or not.

My Auto Td4 freelander doesn't do too badly (02 plate). Struggles with the MAF giving problems when it's really hot weather, but (depending on the size of the vehicle) I wouldn't discount a 2 litre.

Cheers

As a rule of thumb I'd think a 1.3 petrol or 1.4 TD should work ok in a small car, perhaps 1.6 petrol in a medium car, so a 2.0 litre would normally have plenty of grunt to use a slipper box.

One of my pupils is learning in their 1.9 TDi Golf and holy cow does that thing move.

I'd think a 4.2 TD would only need one gear anyway :shock:

My Rangie is fantastic with the auto off-road, is a bit sluggish with the big tyres on the motorways.

A diesel engine has a fairly narrow torque band, so is ideally suited to an auto box, far more so than a petrol engine.
