Tow car information

Hi All

I am in the process of deciding which tow car to buy. Due to the changes in emissions etc most manufacturers seem to be reducing there diesel engine choices and reducing them to 150bhp. Does anyone tow with a 150bhp car e.g. one we were thinking of is the VW Sharan, is it up to the job or do you find them under powered. I tow an Elddis Osprey approx 1400Kg.

Another question. Does anyone tow with a Kia Sorento. This seems like the ideal car but I am interested in the fuel consumption especially solo every day use and are you happy with the towing capabilities. Thanks in anticipation.
