Which XC60 with diesel

Hello forum, happy new year, I have planned for this year to replace my V70 from 2004 with an XC60. Unfortunately I am not so of the technology Freak, but I have heard from the dealer that there are now almost only 4 cylinder engines. But for reasons of smooth running I would like a 5 cylinder diesel and for cost reasons a used one. Up to which model year were 5Cyl. Diesel installed? If I look at mobile or so, I often see 120kW D3 from e.g. 2012. Is the comparable with my previous petrol engine, also 120kW? Need the car as a everyday and touring vehicle. As a towing vehicle, Volvo is unfortunately out of the question. Greeting Thomas
