When asked whether we’ll see the M156’s replacement soon, he said,
“Wait for New York.” They haven’t publicly given the engine a designation yet, but he did that say that the output will not exceed the M157 (5.5-liter twin-turbo V-8), at least not initially. You can assume the car in New York will be the C63 AMG replacement. However, Tobias also indicated that we’ll see the debut of the new sports car,
rumored to be named the GT AMG. This car will feature the new 4.0-liter twin-turbo V-8. The new sports car will cost less than the Gullwing, and that gives the car, “More opportunities,” meaning that you can expect a whole portfolio of variants very similar to the Porsche 911. We can also expect to see the S63 Coupe (and maybe S65 Coupe and S600 Coupe) at the New York show.
