Poor Pensioner

Hi, just joined the club after 4 years of never getting round to it. I have just changed my beloved V6 diesel Stype for a 2013 XF Sportbrake 2.2d. The ride is noticeably harsher and the power unit nowhere near as smooth, but fuel returns are brilliant. Apart from the stop/ start only working once in a blue moon I am learning to live with the difference. Has anyone else had the same issues ?
