2026 NASCAR Short Track Testing Kicks Off This Week

NASCAR begins 2026 Cup Series preparations this week with a two-day Goodyear short-track tire test at Bristol, targeting a stable tire platform and a revised short-track package.

Bubba Wallace for 23XI Racing, Alex Bowman for Hendrick Motorsports, and Ryan Preece for RFK Racing represent Toyota, Chevrolet, and Ford.

Recent events exposed volatile wear windows, from conventional stint lengths to sets fading after 30–50 laps. Cooler conditions limited rubber adhesion, inflating pace deltas while undermining predictability.

The test debuts a 750-horsepower tapered spacer, up from the current 670-horsepower target, to study throttle application, corner entry stability, and passing potential on short tracks.

Goodyear will cycle multiple constructions and compounds, aiming for a tire that resists overheating yet rewards management, regardless of ambient or track temperature.

Those extremes were seen most clearly at Bristol on September 13.

A follow-up at North Wilkesboro is planned to explore additional car changes that could further unlock short-track raceability.

Since 2022, the Next Gen car improved intermediates but remained aero-sensitive on flat shorts and road courses. Trailing cars struggle in dirty air, limiting momentum builds and attacks.

Drivers want the wake reduced. Christopher Bell has argued for Xfinity-like characteristics and even narrower tires, noting current cars slide excessively given the tire grip and power balance.

With diffuser-led downforce, the car sits tail-down and nose-up, stabilizing the leader while making the follower harder to rotate and free on corner entry.

NASCAR will also evaluate a new McLaren ECU and data logger, seeking improved reliability, data resolution, and parity checks for the 2026 rollout.

Crew chiefs are split on solutions. Paul Wolfe expects modest gains from power alone, but believes combined tire, engine, and small aero steps can materially lift race quality.

NASCAR has not finalized the North Wilkesboro plan or participant list. The short-track package will continue to iterate as 2026 approaches.
