On paper, false. In reality, true. LOL
My dad used to have a W211 E55 AMG. It was factory rated (in the US) at 469 horsepower, widely recognized to be complete fiction. Most E55s of that era dyno’d between 410-430 wheel horsepower.… which translates to just over 500 crank horsepower. I did drive it a few times. And it was hysterically quick for a 4,200 lb sedan.
TNP has driven on summer performance tires.
