You raise an interesting point. The “horsepower” wars, esp btw MB & BMW are out of control. When Benz released the AMG 6.3 liter engine that put out 550+ HP they really lit the fuse. They could have kept it just for their S and SL top end models, but they put in their BMW 5 competitor E series plus there former entry class C series. I had a 2002 M5 with 400 HP that was very smooth, body was not overkill like most of the M and AMG cars are now with huge fenders, air intakes, etc. The M5 model after mine had a v-10 making 500 hp, though not a lot more torque; but it’s replacement (F10), came out with base 560/500 with option to kick it up to 575. The F10 was retired end of 2017, and new model released/will be released for 2019 with at least 600 HP, 0-60 in low 3 second range. When will it end?
