Our spies have nabbed what they believe to be a prototype for one of the two upcoming AMG versions of the next Mercedes-Benz S-Class, codenamed W222.
While this test model retains the exhaust pipes of the regular model, it does sport a lowered chassis along with some other telling details such as the side skirts, larger alloy wheels shod in low profile tires, bigger brakes, a covered rear diffuser and a modified front bumper with more prominent air inlets.
The production model will likely feature flared wheel arches and re-trimmed lights as well.
As mentioned previously, Mercedes will continue to offer two separate AMG variants of the S-Class.
The first will be the S63 AMG powered by the current model's 5.5-liter twin-turbocharged V8 producing 530hp (537PS) at 5,500 rpm and 590 lb-ft (800Nm) from 2,000 to 4,500 rpm in standard trim and 556bhp (564PS) and 664 lb-ft (900Nm) when opted with the performance package.
The flagship model will be the S65 AMG, again borrowing the 6.0-liter bi-turbocharged V12 engine with 621hp (630PS) and 1,000Nm (737 lb-ft) from AMG's current crop of models like the S 65, SL 65 and G 65 AMG.
We'll have to wait and see if the turbocharged engines will produce the same outputs as today's S63 and S65 AMG models or if Mercedes-Benz engineers will make some improvements lifting power and possibly, improving their fuel efficiency.
