More torque ?

Something good on going on here, the ol gal has just done 14k, and in the last week, when down here in the 'affluent south' we had early morning temperatures of something like 1-2 degress, my car had, without doubt much more improved torque at lower revs.

Yesterday and this morning the ol gal seemed back to normal, time now to monitor the outside air temps and match against performance me thinks.

Fuel consumption has not changed.

Anyone else notice !

Yeah I noticed this too Pete.

At the Northern meet last week, the air temperature was below zero for most of my 60 mile drive to the pub, but the car (after warming up) was pulling like a train. Even uphill in 6th at 70, I could feel the car accellerate hard up to 85 (all kph, of course wink.gif)

The previous day, when the air temperature was higher and I was driving in daylight, things were not so hot.

The low down power on these TDIs is amaising and still impresses m

Now the new s4, that's the beast - almost as much torque as the S3's maximum at a mere 1100 rpm. Of course, not much more max torque than my 2.5Tdi, but it's the low rpm grunt I really miss.

All A3 Tdi's have intercoolers (110 + for certain)- which love the cold dense air. After a long run on the motorway I notice a fair bit more shove as the pipework and intercooler are all nice and chilled. Sat in a traffic jam will just warm everything up and be detrimental to the performance. This is the ONLY good thing about winter grin.gif
