The concept car that previewed the second-generation NSX at the 2012 North American International Auto Show was the Acura NSX Concept.
Acura unveiled the mid-engine Acura NSX Concept to the public on January 9, 2012, at the Detroit show, officially known as the North American International Auto Show. It announced a major change in the NSX formula: instead of relying only on a conventional petrol engine, the new car would use a hybrid system with electric motors supporting its all-wheel-drive layout.
The concept’s Sport Hybrid Super Handling All-Wheel Drive system paired a combustion engine with electric motors to provide torque vectoring, immediate electric torque, extra power, and improved efficiency. A more refined version appeared at the 2013 show, with styling closer to the eventual production car. The production second-generation NSX debuted in 2015 and went on sale in 2016.
The main source of confusion is Acura’s earlier Advanced Sports Car Concept, or ASCC, shown in 2007. That car previewed possible styling for an earlier, cancelled NSX successor program. The 2012 Acura NSX Concept, however, was the direct concept announcement for the second-generation NSX that reached production.
