TNT Sports is expanding its NASCAR In‑Season Challenge coverage, bringing live races and exclusive commentary to a broader audience across TNT, truTV, HBO Max and Bleacher Report.
A new era of NASCAR broadcasting
The partnership introduces a suite of production upgrades, including 1080p HDR broadcasts that can feature up to 40 cameras per race, delivering crystal‑clear visuals with Dolby Vision and Atmos for a cinema‑like soundstage.
Fans will also have access to a Driver Cam feed on HBO Max, where synchronized audio captures the roar of the engines from inside the cockpit, while a Multiview option lets viewers switch between multiple angles at will.
The commentary booth will be anchored by NASCAR Hall of Fame driver Dale Earnhardt Jr. alongside former crew chief Steve Letarte, with additional insights from Adam Alexander, Jimmie Johnson, Jamie McMurray, Marty Smith, Shannon Spake, Danielle Trotta, Marty Snider, Sonny Styles and other seasoned voices.
B/R Racing will deploy celebrities such as Mac Jones and Dion Dawkins as raceday correspondents, while Mamba Smith captures on‑site moments ranging from driver interviews to pit‑road action, enriching the broadcast with behind‑the‑scenes storytelling.
The 2026 In‑Season Challenge will be exclusive to TNT Sports platforms, marking a significant shift in how NASCAR’s mid‑season slate is presented to viewers.
