Hamlin’s No. 11 Joe Gibbs Racing Toyota was the technical benchmark of the field, leading a race-high 134 laps. He successfully defended a late-race charge from Chase Elliott to win by 0.502 seconds in a high-speed aero battle defined by long-run stability.

Tech Section: 2026 Intermediate Spec

Seasonal Learnings: Las Vegas confirmed the 2026 unrestricted 750 HP configuration provides a significant throttle-response advantage over the previous package. Toyota’s front-row sweep and race dominance suggest their intermediate aero-map is currently the field standard.

Car Package: The Next Gen intermediate package utilizes full aero downforce (larger spoiler and full diffuser strakes). This setup was vital for stability as drivers battled NNW winds of 10-20 mph on the 20° banking.

A-Post Flap Mandate: All cars were inspected for the new safety requirement; body post flaps must deploy in tandem with roof flaps. Underneath, surfaces were verified as bright orange for high-visibility compliance.

Goodyear Tire Specs (D-5284/D-5290): These tires utilized a multi-zone compound designed to "shed rubber." This intentionally high wear rate allowed heat to dissipate from the tire carcass during the record-approaching 81°F afternoon.
