This statement is so incorrect its not funny.
The nsx develops good torgue and power throughout the rev range, that is the characteristics of a 3 litre V6 Vtec. Flat torque curve across the rev range. That is why when others change gear we creep past for 2k more revs.
The RX8 is no comparison to the NSX, the NSX is the only Japanese Supercar, the RX8 is a mass produced, toned down, mum does the groceries family sports car, hence the 4 doors.
Rx8 = nice car but not an RX7 or NSX or Exotic or Supercar
NSX = Supercar, oldie but a goodie.
End of story.
No, the NSX doesn't have power down low.
Of course I'm spoiled with a 514rwhp/489RWTQ daily beater with a superior power plant than the NSX and RX8.
My brother and I have swapped cars to compare and he's even driven the GTO.
We both agree, as well as our passengers is that the NSX and RX8 both need more TQ and HP as well as a flat curve. Neither cars can make the tires spin without dropping the clutch.
