How can it be less stressed if the same mechanicals are producing more power?

Don't know if this is actually true, but my guess based on experience with other makes and models would be: More torque means it doesn't have to work so hard to achieve a given level of performance and can happily pull higher overall gearing. Giving less revs per mile.

OK, so the same mechanicals produce more torque so there must be more load at any given revs.

Yes I agree the idea is counter-intuitive, and the same crank, etc. must have greater load at a given level of revs at the flywheel. I'm just saying there are two sides to the bigger picture and for a given road speed, the more powerful engine MIGHT be working less at lower revs.  But mainly posing that theory as a question, to ask if any of the more technically knowledgeable in here know if that is the case or not?  Not so much saying your postulation is untrue (personally, I suspect it IS true). Just asking if anyone has data on the overall gearing of the two engine outputs?

My take on this is that the 110 and 140 are very similar in mechanical build, more the power/torque increase is mostly due to software changes. The 170 might have a few extra mods, but basically the same block, plus some more software changes

 

If you're only shopping/ driving normally, you wouldn't notice much difference between them all. Yes, if you put your foot down there will be startling differences, but who in their right mind drives taking full advantage of the power/torque increase on a public road? Driving style comes into play as well, zooming away from the lights and braking hard next minute suits some, not me. The 110 brakes are fine for their intended use - I'm sure all variants were tested to destruction before being offered for sale :think:

 

The extra power will take it's toll on the engine long term in some way. You don't need the maximum available power to cruise down a motorway, or go shopping. If you drive to suit the particular engine that's your choice. The higher power versions might well drive uphill in a higher gear more easily, but the loadings will be higher as well - swings and roundabouts.

 

We decided that a 110 would be good for a shopping car, less stressed than the other two variants as we intended to keep it for 10 years. Our experience with our old Rover 25 diesel proved to us that a "large" low stressed diesel was good for 10 fault free years - I hope the Yeti will do the same!

When I had my 170TDI Yeti I took full advantage of it's torque/power on a daily basis,usually when overtaking.

However ,being in my right mind ,I 've always tried to avoid unnecessary braking.

Unless you are always aware of the engine revs and how it is pulling there will certainly be more stress on the DMF (viz. juddering). I'm all for anything that gives me a more leisurely life!

That's why I've just ordered a 140 DSG to replace my 110.

I guess you do more aggressive shopping

No I reserve my aggression for non-motoring events, like poor refereeing decisions against Liverpool FC.

Afraid you must have been very aggressive lately then
