The Wookie said: Doing a fair amount of work with gear ratios I've often wondered this. From my experience of driving diesels I usually put it down to them being quite easy to stall I have always found them much harder to stall, especially an old Peugeot engined 2.5 litre turbo 1990 Granada I had once. I routinely manoeuvre my diesel engined car (Mondeos of various vintages mainly) on idle with no danger of stalling unless I'm ham-footed.

I take it nobody knows then  I'm currently driving an Avensis and despite less power and a narrower powerband it has very long gears compared to my 123d! I very much doubt its to do with stalling as the Avensis seems no keener to stall than my usual car. Although I finally understand the gripes about diesel power delivery. Nothing between 1-2k, 2-3k power!!! 3-4k it slowly dies

This is up to 1800KG, so first gear is very low. And people do test these things at MIRA...... http://www.galwayindependent.com/motoring/motoring...interesting. Brilliant response to revive a 3 year old thread. Well done.

On the subject of this. My father's 3 series never uses first gear unless you specifically change into 1st in manual mode. It always pulls away using second gear with first gear being so short it is redundant, whereas in the Panda 1st will see you up to about 20-25mph.

The Merc 7G-tronic box is similar, when in 'sport' mode it will pull away using first otherwise always second. Puzzling thing about that box is that it has 2 reverse gears - slightly unnecessary!

The lag is horrific due to the long gear ratios - first gear is a must without burning the clutch.

F i F said: Somebody demonstrated to me quite a good way to get lightly laden diesels off the line, at least on the flat or slightly downhill.
Basically pull away in second. Feed the clutch in gently which gives a granny start for the first yard or so, but after that clutch fully engaged and floor it. The saved change more than makes up for the granny start. Seemed effective to me, and I know from his fleet records he's never had a clutch changed in the last ten / twelve years. Only way I used to be able to get my 123d off the line at a reasonable pace. In first it'd get murdered due to the gear change needed. Off the line in 2nd then to 4th used to deal with most stuff - otherwise it was embarassing being seen off by transits

My Diesel car has never been officially tested for towing and is not allowed to have a towbar fitted,so that's a load of nonsense IMO.(2006 FABIA VRS in case anybody is going to ask)

kambites said: I doubt they take towing into account much when designing, say, a Yaris diesel? Probably not but I tow with mine and it handles light loads very well. I haven't tried probably more than 1/2 tonne with it though. The only annoyance, with or without trailer, is that entrance speeds onto a busy roundabout can be a little high for 1st gear but fall out of the range of the turbo in 2nd. Very torque light until the turbo kicks in.
