Three-Wide Overtake Lab
Simulate the aerodynamics, slipstream vacuum, and lateral side-drafting forces behind high-speed three-wide passes on superspeedway ovals.

Backstretch into Turn 3 (Banking: 31°)The Physics of a Three-Wide Stock Car Pass
1. The Leading Slipstream Bubble
Two side-by-side leading cars punch a massive turbulent wake behind them. A trailing car nestled in this low-pressure bubble experiences up to a 35% reduction in aerodynamic drag ($C_d$), creating an engine RPM surge and massive closing velocity.
2. The Side-Draft Air Deflector
When the chasing car draws alongside another stock car's rear quarter-panel, air spilling off the trailing car's nose strikes the rival's rear spoiler. This increases turbulent drag on the competitor while momentarily stalling their forward momentum.
3. Split-Second Middle Squeeze
Threading the needle between two battling competitors is the highest-risk, highest-reward maneuver in motorsport. The center car receives clean air onto its front splitter while starving both flanking competitors of balanced downforce.
