Joey Cohen joins Bozi Tatarević on Episode 3 of the Bozi Breakdown to dissect the recent Texas NASCAR race. Their discussion centers on the track’s unique challenge: two distinct ends that demand strategic compromises from drivers and teams.
The conversation pivots to the Next Gen car, specifically its aerodynamic profile, or "aero attitude." Cohen explains how the car generates underbody downforce through the rear diffuser—a critical factor in high-speed stability and cornering performance.
Cohen also addresses the complexities of racing in a 35-car field. He emphasizes the stark contrast between single-car testing and real-world racing, where traffic dramatically alters the car’s aerodynamic sensitivity. Planning for races becomes exponentially harder due to this variability.
