Aero explained: Why the Aston Martin Valkyrie is in a league of its own

There are three fundamental ways to make a car faster around a track; add power, add mechanical grip, and improve aerodynamics. Modern supercars have been pushing the limits of power and mechanical grip more and more, with 1000+ hp and grip levels beyond what mortals are capable of driving to. However, from an aerodynamic standpoint, almost all of them are still in a completely different league to the likes of F1 and LMP1.

Enter the Valkyrie. Aston Martin decided that partnering with one of the best F1 aerodynamicists out there, Adrian Newey, would result in an excellent road car. The fruit of that collaboration is the most extreme aero package ever fitted to a road car, but unless you have a PhD in aerodynamics, it may be a little hard to understand what's going on. The aerodynamics of the original AMRB-001 concept have been well documented in another one of my videos, so in this one we'll stick to the upgrades for the more "production" spec version. The whole car has clearly been designed around aerodynamic efficiency, so expect high downforce and low drag. A downforce figure of around 1800kg has been reported, but we are yet to see at what speed that number was achieved.

At the front of the car the package has been updated with an F1 Y250 style vortex generating winglet, instead of the previous design's continuous wing. Air from this section has been far more aggressively vented, with vents over the top of the bonnet and a more angled front tyre vane. The new version has a more aggressive front tyre wake management strategy in general, which will result in both improved venturi and front wing performance.

The key design changes on the car have been focused on the airflow management in the venturi tunnels, particularly around the rear of the diffuser. A significant lateral expansion has been added, providing a lower pressure region at the rear and improving extraction through the whole tunnel. The tunnel section has been reshaped to house a large scale vortex structure, improving total downforce and flow attachment through the diffuser region.

There are a few other more technical details discussed in the video, so why not check that out! And leave a comment below on your thoughts on the Valkyrie.
