AMG’s senior powertrain engineering manager, Jorg Gindele, has revealed the company is testing a C63 AMG 4MATIC.

Speaking to Auto Express, Gindele said the company has already built a prototype and he knows this "because it’s my car.” Gindele withheld details but said the model is currently being evaluated and could be approved for production.

Gindele also confirmed AMG is developing an all-wheel drive version of the next-generation S-Class. He didn't say much about the model but it is likely the S63 AMG 4MATIC.

More interesting, Gindele said the company will offer an E63 AMG Black Series towards the end of the current generation's lifecycle. There's no word on what will power the model, but we wouldn't be surprised if it is more powerful the E63 AMG S which has a twin-turbo 5.5-liter V8 engine with 585 HP (430 kW) and 800 Nm (590 lb-ft) of torque.
