M9R cold weather performance


I'd like to hear from other diesel owners about whether they notice any significant difference in the performance of the M9R engine in colder weather.

I live in Canberra and in the winter we regularly get temperatures into the single digits, and occasionally a minus figure.

I find on those particular mornings the M9R seems to perform exceptionally well. It's particularly noticeable at the fuel bowser where I reckon my fuel consumption improves by up to 0.6L/100km compared to my summer consumption figures. I also notice improved power output.

Could it be simply the denser air is helping the turbo diesel engine breathe better?

Re:


Cold Air is excellent for a turbo diesel engine. Not only our X-trails, but noticeably on the bigger 4.2 engines in the Patrols and Landcruisers.

Our X-trail performs very well in cold temps, have had the warning light come on a few times to tell us its cold outside (3 degrees or lower) and the x-trail has performed faultlessly. Fuel economy is much better.

Ideal conditions for a turbo diesel.

Re:


As a fellow canberran, my TS always a bit more fun to drive - especially coming through the southern tablelands where the temp drops and the air seems a bit 'thicker'.

The only issue I have with the x-trail during winter is it goes into limp mode after being on cruise control too long (leaving Belco, i've had 2 limps with 10kms of lake george; similar issue around berrima when heading from Sydney to CBR). Didn't happen last winter (but with this weather at the moment, wouldn't surprise me if I got it during summer LOL)

Re:


Simple answer is denser air charge from cooler air intake temp.
