Development of Sports Car Sound for Hybrid Super Sports Cars

Article of Honda R&D Technical Review Vol.29 No.1


Developing the sports car sound for the next-generation Acura NSX Sports Hybrid required a unique approach to vehicle noise and vibration development. Starting with a holistic acoustic strategy for the vehicle platform design, insulation package and chassis isolation specifications were constructed to accentuate cabin quietness during hybrid driving. Employing multiple acoustic technologies, devices and control strategies, specific frequency and order content was enhanced to maintain the original NSX heritage sound while adding functional purpose to audibly communicate instantaneous power unit feedback to the driver. Execution of this strategy achieved the vehicle sound concept and the hybrid super sports car segment competitiveness was redefined.
