The Aston Martin Vulcan generates its GT3-levels of downforce via its prominent front splitter, rear diffuser and adjustable rear wing.
Aero Target Setting
In CFD Testing (Computational Fluid Dynamics) the car was run at the following two settings:
- 60 mm front ride height and 80 mm rear
- 40 mm front ride height and 100 mm rear (Braking)
Results - Aero balance front:rear is 41:59 at ride height
- Balance change of only 7% under braking
- Downforce at 100 mph is 324 kg
- Lift:Drag ratio is 2.3
- Total downforce at Vmax is 1362 kg
Summary
The aerodynamic balance has been set up to ensure minimal change in pitch sensitivity and balance either forward or back under braking or accelerating. This benign behavior enables more stable for driver feedback ensuring owners become confident with the additional levels of grip the downforce can generate.
