Acura hasn't revealed the car's weight, power, or other specifications, but does says that "While most super cars opt for brute force delivered from a large engine, the NSX Concept champions the true racing philosophy of an extremely favorable power-to-weight ratio. Like the first NSX, we will again express high performance through engineering efficiency."
Though the original NSX (which also used a mid-mounted V-6) was a potent performer upon its release in 1990, the Nissan 370Z, Hyundai Genesis Coupe, and many other affordable mid-range sports cars of the last few years offer similar or better performance for much less expense--and without the supercar aspirations. The new NSX will have to be a significant upgrade, which means more power than the original, less weight, or both.
Acura's power-to-weight statement bodes well for the NSX being a lightweight, road-hugging special, but at the same time, packaging a V-6 engine with an all-wheel-drive hybrid drivetrain is likely to weigh well in excess of 3,000 pounds--perhaps as much as 3,600 or more. Given that Chevy's Corvette Z06 and ZR1 both weigh in at the middle of that range and pack 505-638 horsepower, and the Italian and German exotics add exclusivity and extreme high tech to the mix, defining the NSX as a "supercar" may be a bit of a stretch.
But we don't care. The NSX is finally coming back, and it looks great.
