Revealed at last year's Detroit Auto Show, the NSX has returned to Motown this week with a subtle styling tweak and, at last, a complete interior.
Dubbed 'NSX Concept II', the madeover coupe gets a reworked face with a wider and de-blinged grille, along with a similarly subtle smoothing out at the rear.
In the cabin, the NSX is all-supercar, featuring a high-rising centre console, a mix of leather and suede trim, and a large screen in place of the traditional instuments behind the steering wheel.
Mechanically the concept remains unchanged, with power derived from a mid-mounted naturally-aspirated V6 engine and a set of electric motors - one at each wheel for all-wheel-drive grip.
"This Sport Hybrid SH-AWD system will make NSX the ultimate expression of Acura's idea to create synergy between man and machine," Takanobu Ito, Honda President and CEO, said.
"The NSX will make the driver one with the car to enhance dynamic driving abilities without getting in the way."
Power figures haven't been revealed, but if the V6 is the new engine announced late last year, we can expect at least 231kW - plus whatever boost the electric motors bring to the table.
Tucked into a lightweight body loaded with aluminium and carbon fibre, the hybrid powertrain should give the new NSX a 0-100km time in the low four-second range.
"This further evolution of the Acura NSX Concept design is remarkably true to the original concept styling," Acura's Mike Accavitti said.
"We're making great progress in delivering on the expectations we created a year ago, with advanced technology that will bring new levels of performance and a unique, dynamic experience to the exotic sports car market."
The NSX will make its North American production debut as an Acura model in late 2014, with a global debut - under the Honda badge - to occur in the following months.
