In that instance is there any point in revving past 7000-7500, surely you snick a bigger gear and keep accelerating?

My mate had an Sl55 AMG with about 500bhp and a Ferrari 360 with a little more, he said that the AMG always walked away from the 360 as the 360 needed nearly 9000 rpm to make the power and was well down on torque, the AMG made more torque overall and power lower down and just pulled a bigger gear earlier so drove away.
