Good morning to the forum. I’m new here. After long years MB I would like to try an XC60. I started looking for a used XC60 with the 5-cylinder diesel. The engine is offered in three power levels. I would prefer the 205 hp or 209 hp with Geartronic. Can anyone explain to me what this 4hp power difference results. Is one or other variant to prefer? Thank you sid2006
