The model recently started production, and its first example was snatched for the cool payment of $1.2 million – but engineers still like to brag about their achievements.
Engineers, like any other humans, like to boast their credentials in front of others. And this is a perfect example – as the Acura NSX aerodynamics and Cooling Project Leader, Thomas Ramsay, has delivered some new insight into the car’s “Total Airflow Management” concept. It turns out the engineers had to “totally re-imagine the exterior engineering for this modern supercar” because the NSX was from the start looking to reduce drag and lift the downforce levels. The initiative included computational fluid dynamic (CFD) simulations to see how the car performs in the virtual environment. And then there were 40 percent scale models to see if th simulations were right by submitting them to real-world tests at the company’s wind tunnel testing facility in Ohio.
The prototyping showed the development team the right directions, customizing the car’s intakes, exhaust vents, and body surfaces to reduce drag and generate downforce. After lots of R&D, the team knew the NSX would need about three times more downforce on the rear axle than at the front. For that, they used a rear spoiler and rear diffuser, while the front end was also designed to direct the airflow into the intakes.
