M156 6.2L V8 is the HIGHEST Output NA Production V8 Ever
The speciale is actually #3 on the list because the N/A V8 in the 918 Spyder produces 608HP vs the 597HP in the 458 speciale

It is the highest output - in the AMG SLS and c63 507/Black Series - and it's highly unlikely to be topped, since everyone's going to turbos.
The new Mustang is supposed to have just over 500 hp, so we'll see what it actually does when it comes out.
For this reason, and others, the M156 will be a future classic!
I'm proud to soon be the owner of one.
