http://www.carmagazine.co.uk/ report that new CEO Steve Odell was rather confused by the odd badging regime used by Volvo to date, i.e. the C30, S40 and V50 are all built on the same underpinnings.
The new S60 will be the first car to slot into the new naming system in August 2010, fitting in neatly alongside the XC60 and the to-be-announced V60 wagon.
The same logic will be applied to all future model lines, cutting down on a range that current spans from 30 to 90; the S, V, C and XC letters will continue, however.
