The 2013 Mercedes-Benz S-Class has been caught testing. Make sure to watch!
Due for launch in late 2012 as a 2013 model, the new S-Class is expected to be slightly longer than the current model and come packed with a range of fuel efficient engines as well as a new plug-in hybrid option. The test mule seen here sports a slightly longer bonnet and wheelbase, suggesting the overall size of the S-Class will grow. Hidden under the front camouflage are the new air intakes and grille, with engineers most likely testing airflow to the engine bay.
