Here’s a little snippet I recorded with my phone. To be honest, when I go to races I tend to focus on the experience rather than watching it in low res on a phone screen. But I digress, here is the SVRA Group 9 cars (Formula 1, CART, Indy, and various other post- 1973 open wheel aero series).
The car in first is this 1997 Benson & Hedges Jordan.
And second is this 1997 Benetton.
