I had the same disapointement with a 2011 Mondeo SW 1.8 econetic. I could not belive the 800kg limitation! Even my Tourneo 1.0 has more towing capacity (860kg)! I've contact Ford here in Portugal and one of the engineers explained me it was related to the econetic and the engine conception. ! It's absurd! I sold it and bought a 2001 Ghia! 1850 kg !
