Officially unveiled in May 2013, the newest S-Class has a more streamlined appearance than the outgoing model. Some interesting features include a large front grille inspired by the F700 Concept car and LED lights used exclusively inside and out – a first in the automotive industry. Two strong converging character lines give the flanks a more sculpted look, while integrated exhaust tips and a large glass roof (likely optional) highlight the design. Along with the sedan, the S-Class spawned a coupe (Mercedes-Benz C217) and convertible (Mercedes-Benz A217), as well as an extended-wheelbase 'Pullman' variant, longer than the long-wheelbase 'L.' While the short-wheelbase model, carries chassis code W222, the long-wheelbase model uses chassis code V222. Unlike previous generations, Mercedes focused primarily on the development of the longer model as many customers in the fast-growing Asian markets prefer to be chauffeured. In 2016 Mercedes W222 was the last car with an S65 AMG engine.
