I have just recently purchaesd the auto D5 and we find it a terrific vehicle.... economical and swift.
My question concerns the power output for this model.

Apparently this motor in any other model produces 400Nm whereas the S40 5 speed auto version is restricted to 350Nm. (the upcoming 6 speed manual will use the full 400Nm version).

My guess is the 5 speed auto is considered a little underdone for such torque and hence the restriction.
Do anyone know how torque is limited on these models, whether by the computer management system or mechanically.


Thanks in advance!

Steve, I don't know for sure how the torque is limited, but I would suggest electronically as it is so easy to do with Electronic Engine Management.

If you fancy 205 PS / 400 Nm, then you might like to think about a Heico upgrade.

As far as I know, their products are unofficially endorsed by Volvo, so I don't think there would be any probs with the auto handling the extra power and torque.

Thanks very much Stewart... I didn't know this company existed.... it certainly looks like the engine management system is the culprit.

I'll see what prices they can offer! 400Nm pushing 1450kgs..hmmm! :P
