How the McLaren Speedtail stole its shape from Mother Nature

5w ago


McLaren’s new hypercar is here – the 1036bhp, £1.75 million Speedtail. With its three-seater nod to the legendary F1, it looks like this new halo car will go down in history as one of the company’s all-time greats.

One of the stand-out features is its stunning aerodynamic design, so our in-house engineer Mike Fernie is here to take you through why the car’s teardrop design is pivotal to it reaching its sizzling top speed of 250mph.

What would you like Mike to explain next? Drop down into the comments with what you’d like to know!

    Its shaped by the laws of physics

  • Please stop perpetuating the lie that a tear drop is the most aerodynamic shape. IT IS NOT. It is was a good place to start. It led human kind to figure out the airfoil (aerofoil) as you mentioned. I am really glad you at least mentioned that. The airfoil you used is a great one for illustration, but it is from like the 40s or 50s. If you look top down at a jet or F1 car you will see that no one uses that shape anymore. Testing in wind tunnels changed the shape to a thin diamond with the sharp point being the direction of travel. This led planes to go super sonic and gave us all the awesome wedge shape cars from the late 60s to the 80s. The problem with this is that if you have a airfoil where the air has less surface to travel on the bottom than the top you create lift. This is why all those wedge cars ended up getting spoilers to push them back down. What McLaren brilliantly did was to create an airfoil that produces less left. Notice on the side profile of the car that the angle of the back end almost matches the windscreen.

    • i atually always questioned it from the first time i eard it, like wtf no, the tear drop as a round base because its resisting air, the arrow shape sould be the most aerodinamic shape,...
