Thanks to our friends at GMotors, we have the latest round of S-Class Spy photos. Mercedes engineers have been testing the new S-Class for quite a while and this time around, the photogs believe it is the Mercedes S63 AMG, featuring the new AMG-style squared double exhaust outlets they caught.
Besides the AMG-style squared double exhaust outlets, noticeable features include larger brake discs, bigger air intakes and an updated new bumpers, when compared to the standard S-Class.
Power is expected to come from the recently introduced M157 twin-turbo 5.5-litre engine that produces up to 571bhp.
