Decision-making aid

Hello all together, new car is on and I can’t decide. to choose from: xc90 diesel summum or sport the xc90 I find very nice and practical, I only have the fear that it is too lame in the long run. I drive in the year at least 30,000 km and also like a little bit more brisk. or should I wait for the new V70, which comes in the summer. Maybe you can give me a few thoughts, would you really appreciate it! Greetings
