The NSX nameplate is coming back, maybe. We have heard this one before but the rumors of a V10 powered successor to Honda/Acura's supercar had a shelf life of about five months. This round of buzz has the flagship returning with another V6 but this incarnation will be backed by an electric assist motor. That's right, a hybrid. But this sports hybrid will bring 400 horsepower and all-wheel drive to the party. The Acura Sports Concept is automotive eye-candy.
