63 or 65 is the manual engine with the largest number of cylinders manufactured by a series of Mercedes-Benz cars. For example, C63 is an 8-cylinder manual engine, and S65 is a 12-cylinder manual engine. For example, S600 is also a 12 cylinder, but the engine is not made by hand. Each car also has a maximum number of cylinders, with C having a maximum of 8 cylinders and S being 12 cylinders.
Configuration depends on how many entertainment systems and security systems are installed in your car or whether they are advanced. Every car comes standard and optional, even AMG comes standard and optional, but AMG can choose more and better.
