Kaufberatung XC60 Diesel 4 or 5 cylinders?

Hello together, currently driving an XC60 BJ at the end of 2012 with 163 HP automatic. I am very satisfied, the 5 Zyl. I like very much. Will again buy a newer XC60 an annual car in the spring, so BJ. 2014. I am not sure if I should take the “old” 5 Zyl. or the new 4 Zyl. with 181 HP Euro 6 with 8 gear automatic. Is there anything negative about the new 4 cylinder? (except the loss of the 5 Zyl. sound) Didn’t really find anything in the net. On A llrad I am not instructed to live in the north. Greetings Steve
