Well get a look at this......
First off, I don't know why I just learned this (if these stats are true that is) because I'm such a car nut I should know these things, but a fellow forum member PM'd me about bench marking the SRT-8's performance against the likes of the AMG family and I came across this:

GREAT GOOGLY MOOGLY!!!!
So let me get this straight....The similarly weighted, but only 16 more HP (if you consider the SRT-8 is underrated at 450HP which I believe it is) but a little more significantly out torqued E55 AMG does 12.5 in the QT BONE STOCK!!!!
The SRT-8's that are supercharged and injected with nitrous at around 500RWHP don't run this times.
So what gives? I can only say the E55 AMG is Also EXTREEEEMELY underrated.
What say you?
