I checked with Volvo and the explanation is: “2009MY DRIVe cars @119g/km had body styling as standard. With 2010MY, customers have the choice of a DRIVe with Start / stop and all of the styling @104g/km or a 'standard' C30 DRIVe without the additional styling @119g/km. The 'benefit' that the styling created in the MY09 is made up for in engine enhancements in the MY10.” Volvo continues, “ we've been very clear with the dealer network from the outset of the benefits of both cars because we saw this as a potential problem. Coincidentally, we reinforced this with a communication to dealers in the last 24 hours. So, your customer has got the right CO2 that he thinks he should but it's just a question of whether it should have styling or not, based on the historical precedent that it does.”
