As a happy owner of 330d, 135kw, 2001, the consumption is between 7,6 l /100km and 8,2 l/100km... I definitely recommend this, the first reason is that the torque (410 nm) is higher than at Porsche 911 (2001), the elasticity is enormous, and the diesels may run and withstand much more kms than classic fuel engines... the last reason - tak a look at the latest 330d with 160kw, this engine is in all aspects a miracle, better than 330i!
