the aston martin one-77 engine is the most Powerful Naturally aspirated engine in a production car
hear are some stats
7.3 V12
750bhp
220mph
0-60 3.5
the one-77 engine is the same size as the cinque engine but with the one-77 you get a lot more power.
i wish AMG could get that power out of their engine for the pagani zonda cinque. that would mean if they did it would be a powerful as the zonda r
