The futuristic update of Honda's iconic 90s sports car made its debut at last year's Detroit motor show but it returned to Motor City this week with some styling tweaks and a proposed production date of 2015.
A new aerodynamic grille cover is the first noticeable update to last year's concept and eye-catching alloy wheels add an extra dollop of visual drama.
The interior was unveiled for the first time this year and Honda has said it's just one direction the final product may take. Swathes of red leather and carbon fibre cover many surfaces while dials and binnacles are cleverly laid out so the driver can focus 100% on the road ahead.
The original NSX featured a 3-litre V6 that produced 270bhp and although the new version's powerplant boasts the same amount of cylinders, it will be mated to an electric motor and an all-wheel-drive system for potent performance figures.
Jon Ikeda, head of design on the NSX project told Autocar: "This project is evolving all the time, and we wanted to reflect that with the concept. What is most amazing is how little the exterior has changed. What you see on the exterior is a more focused look at our goal of creating the modern performance car. It must be futuristic, be simple but technical, and express the performance and technology leadership we want to take."
