Volvo has fallen foul of not updating their models in the past and so they are keeping on the ball with their S60 and XC60. These two models are fairly new to the market but they are already looking to changing their styles.
When the two cars entered the market they had a new style but it looks like they both have changes planned for the future. The spy photos imply that they will look more like the V40 hatchback which is a rather nicer looking vehicle.
The XC60 will be pointier at the front and the back will also look different and have two outlets for exhaust. The S60 pictures show the interior and it looks like the front seats will have a new design as well as the shift lever being changed.
