Tuatara | Unmatched Aerodynamics

An extensive aero study validates the Tuatara as the most aerodynamic hypercar on the market today. At just 0.279, its low coefficient of drag is a vital component in achieving 300+ mph.

awesome

Impressive, what is the frontal area of this car?

incredible

who is here after Tuatara hit 331 mph?

Have you used the same 3d model for achieving that number of Cd, or you tested the car in actual conditions, complete with rotating wheels, brake disks and the corresponding air turbulence around the wheel wells, working fan radiators, heated and expanded air from the radiators and engine bay, various small turbulences around the panel gaps, windows, windscreen wiper, underbody paneling etc? According to my experience and judging by what I have seen in the videos and photos of the Tuatara prototype shown recently in some public exhibitions, the real Cd will be something between 0,35 and 0,45.

AutomotiveCNC This video is a very small insight into the extensive aerodynamic study done to validate the aerodynamics of the Tuatara.

@@SSCNorthAmerica , the biggest difference between real-world streamlines and the computer generated ones that I see on this video are on the sides, especially the front wheel wells. Air stream on actual cars never goes straight to the door panels. Instead, they produce a vast amount of turbulence similar to what's shown correctly on the rear bumper of your CGI animation. Also, I'm curious whether the streamline that comes from above the front fender (it's actually a clamshell) really continues its flow smoothly towards the upper portion of the doors and upper side air intakes? I'm asking this, because from my practice I learned that this particular upper streamline tries to rapidly go down right after the front wheel, further contributing for the turbulence in that area. The point is, that same air was initially raised by the very low front bumper shape, then goes over the front fenders and tries to find the quickest way to go back to the original level it was taken from.
PS: Sorry for my poor English, I hope you can understand what I mean.

@@AutomotiveCNC they finally did it, means it worked out

[@AutomotiveCNC]

@@areenbhalekar949 , do you know the actual (real, true) Cd for Tuatara? I'm aware about the recent speed record and that's fantastic, but the Cd of the actual car is definitely higher than the claimed number of 0.279 for the 3d model that uses closed flat wheels and has no rotating mechanical components underneath the body.

[@areenbhalekar949]

@@AutomotiveCNC idk, but jesko has cd of 0.278 what do u think about that? And the McLaren speedtail also has low cd.
But the jesko absolut has covered it's rear wheels whereas speedtail has covered it's frontal wheel.
This confuses me, which is more effective and which is less
