Hi,
I had until recently a 55 plate XC90 D5 with the 5 speed geartronic gearbox (163 BHP), good family car and good for towing, as for fuel, when solo I was getting 23-25 around town and 36-38 on a run (70 mph with cruise on)
I sold the car due to running costs and for the first six months it was back at the dealership for some niggles to do done to it (luckily under warranty), but due to high fuel costs spending on average
