First Sight: Mercedes-Benz SL

The new high-tech, low weight Mercedes SL roadster receives its official global unveil next week in Detroit but Car Design News got an early peek of the final production car and had a chat with its designers at Mercedes' US advanced design studio in Carlsbad, California back in November.

"So the new SL is long, sleek and still full of tension in the feature lines but less wedgy." In a short presentation Kohl felt all SLs became successfully iconic in their times because they followed two key rules – ‘sensuality' and ‘cleanness' – but alluded that the first rule may have been lost in more recent eras.
