XC60 D5 EU5 or EU6 Fuel Consumption

[niva441]

Hello all

I'm currently running an EU5 XC60 D5, I'm thinking or refreshing it but not convinced by the UK specs of the current range. Therefore I'm thinking about a late old model XC60. I see from the specification that in addition to the better emission certification to EU6, the official emissions are reduced from 169 to 149 grams and the fuel consumption is reduced. Is there any actual improvement in real life fuel consumption?

Also is the drivability affected, I'm assuming the extra couple of bhp makes minimal difference.

Thanks for your time.
