For the time they made pretty good engines at AMG. Today they are outrageous. They lie about the numbers. The E63 AMG is claimed to be 577 hp. In a television dyno test where the car test crew did not believe the hp vs. the 0-60 time. The dyno and estimates of AWD drivetrain loss estimated in the high 800 hp range.
? Times are OK for #/hp.
That should be “in the high 600 hp range”. Sorry, typing at night and not much light on keyboard.
