V50 1.6d or 2.0d ??

Stand before a purchase decision: Either the 1.6d or the 2.0d. Drive so 25000 km a year, but not much highway, rather rural road and imagine me to have a foreseeing driving way. Do not have the ambition to be the first at the traffic light. In the brochure stand as consumption data for 1.6d 5.0 liters and for the 2.0d 5.8 liters. But if I look around in the forum, no one can achieve that. What have you done for experiences? Which engine is recommended?
