Overview

• The Cup Series will move from roughly 670 horsepower to a 750-horsepower target in 2026 at designated short tracks and road courses, with a published list that includes venues such as Circuit of the Americas, Watkins Glen, Sonoma, the Charlotte Roval and Martinsville.
• NASCAR officials outlined a phased rollout that begins with post-season testing in December at North Wilkesboro to study tire degradation, handling and engine durability before any expansion.
• Kyle Larson urged fans to temper expectations after a recent test where he said the increase did not feel dramatically different, while Chase Elliott called the move a reasonable trial that could inform future steps.
• Chase Briscoe backed the decision and expects the added power to increase tire wear and put more in the driver’s hands, with John Hunter Nemechek and Josh Berry saying the effect may be incremental but directionally positive alongside ongoing tire work.
• Criticism persists from some former insiders, with Brian Keselowski noting his 2007 ARCA engine produced around 800 horsepower at lower cost, highlighting debates over whether the boost is too conservative.
