Fear not, though, the 2013 Mercedes SL-Class has already been spotted a
number of times, each time with less camouflage than before. With this
new generation, Mercedes hopes to achieve a lighter sports car. In fact,
they have announced that the next SL-Class will be the first Mercedes
model produced in large series to use an all-aluminum bodyshell that is
about 242 lbs lighter than a comparable steel bodyshell. As a result,
the new SL 500 weighs 275 lbs less than its predecessor, while the SL
350 weighs the above-mentioned 308 lbs less than its previous version.

The new 2013 Mercedes SL-Class will be making its world debut in January
2012 at the Detroit Auto Show, but Mercedes will be offering its
official specs on December 15, 2011. Stay tuned!
