NASCAR confirms horsepower increase for 2026 at 17 tracks
NASCAR has confirmed a significant technical shift for the 2026 season, raising engine output from 670 to 750 horsepower at a total of 17 tracks. The move signals a clear intent to alter the competitive dynamics of the Next Gen era and could reshape team strategies, car setups and the on-track product at a substantial portion of the calendar.
What is changing
- Power increase: from 670 hp to 750 hp
- Scope: 17 tracks across the 2026 NASCAR Cup Series campaign
- Timing: effective for the 2026 season
Why it matters
A higher horsepower ceiling is expected to influence throttle response, corner-exit acceleration and overall race pace, with potential knock-on effects for tire wear, brake management and fuel strategy. Teams will likely revisit aero balance and gearing choices to match the new power band, while drivers could face a more demanding car at certain venues.
Although the specific list of tracks was not detailed in the announcement, the breadth of the change suggests it will affect a wide range of oval configurations where power application and drafting dynamics are critical factors.
Impact on the racing product
The step up in performance may reward precision and car control, particularly over long green-flag runs. It could also alter passing zones and make restarts even more decisive. Fans can expect the conversation around setup windows, drivability and race craft to intensify as teams adapt to the new baseline.
What teams and manufacturers will be watching
- Cooling and reliability under higher loads
- Drivability in traffic and managing dirty air
- New balance between qualifying trim and long-run pace
- Pit strategy to mitigate increased tire degradation
What’s next
Further technical guidance and implementation details are expected to follow as the 2026 season approaches. Teams will prepare with simulation work, dyno programs and targeted test plans to ensure they roll into the new year ready to capitalize on the increased power window.
