I am trying to assess the new Avensis 2.2 D-4D Tourer as a towing vehicle for an ACE Viceroy (1,161Kg unladen wieght)caravan. The new Avensis model now has 148bhp, torque of 310Nm, max nose wieght of 75kg, 6 speed manual gears and a kerb wieght of approx 1,500Kg. I have read some poor feedback re the 2.0 D-4D model. Can anyone share towing experiences with the new 2.2 model. Is there a significant improvement.Thanks for your help.
