"article": "Listeners, welcome to your daily auto racing digest. Yesterday delivered high-speed drama in NASCAR, Formula 1, and key developments behind the scenes that every fan should know. At Phoenix Raceway, the NASCAR Truck Series crowned a new champion—Corey Heim clinched his record-extending 12th win of the season, surging from 10th on the grid for a dominant championship victory, capping off 2025 with consistent supremacy. Notably, Layne Riggs took pole position with a pace of 26.707 seconds but had to start from the rear due to a post-qualifying inspection issue, bumping Chandler Smith to lead the field at the green. Heim’s run was the talk of the paddock, with risky overtakes into Turn 4 and decisive pit stops under a late caution that sealed his triumph. Listeners lauded Heim as driver of the day for his relentless advances and tire management, beating top contenders and making history for the team.\n\nThe NASCAR Cup Series Championship weekend saw intense practice at Phoenix with Ty Gibbs setting the fastest lap at 27.300 seconds for Joe Gibbs Racing. Among championship contenders, Denny Hamlin was fastest, fifth overall, including stars William Byron and Kyle Larson who cracked the top eleven. Drama spiked with multiple tire failures for Chase Briscoe—who struggled with vibration—plus wall contact for A.J. Allmendinger and Riley Herbst. Ryan Blaney showed solid long-run pace, positioning himself as a threat for Sunday’s title decider. Repairs and tire investigations dominated the garages as teams worked late to perfect setups for qualifying.\n\nOver in Formula 1, anticipation built for the Sao Paulo Grand Prix at Interlagos. Lando Norris leads the F1 championship after his recent Mexico City win, holding a razor-thin margin over Oscar Piastri, with Max Verstappen just 36 points back as the grid arrives in Brazil. Qualifying raged under threatening skies, rain looming over all three days—a classic Sao Paulo wildcard. Local hero Gabriel Bortoleto’s rookie homecoming drew big crowds, with the track’s Senna S and sweeping final sector prime for breathtaking overtakes. Experts pointed out Bortoleto’s impressive Mexico performance, but all eyes are on Norris and Piastri, whose McLarens are top contenders yet face mounting pressure after teammate criticisms and Villeneuve’s blunt commentary.\n\nCore stats for the hardcore fans: Heim’s Truck Series win marked an average lap speed exceeding 130 mph, with more than a dozen on-track passes and only two cautions disrupting racing flow. In F1, lap times tightened in practice, McLaren and Red Bull trading top-three spots in every session, while Norris edged Piastri by just 0.2 seconds in a head-to-head Quali run. Verstappen remains a disruptor, with 67 career wins and 122 podiums heading into Interlagos. Technical breakdowns revealed Haas’s Ollie Bearman leveraging DRS and downforce setups for his surprise top-four result last race, fueling Ferrari rumors as Hamilton’s future remains unresolved.\n\nQuotes from the pits: Corey Heim called his title run 'the best season of my life,' crediting tire strategists for 'a car that stuck in every turn.' Denny Hamlin reflected, 'We’re right where we need to be, just got to get it perfect on Sunday.' Jacques Villeneuve blasted Piastri’s form, saying Norris’s title lead exposes 'double standards' in McLaren strategy. Team news included Freeway Insurance joining NASCAR’s Cup Series partners, and Haas celebrating Bearman’s potential Ferrari move after Mexico’s breakout.\n\nLooking ahead, NASCAR Cup drivers prep for Phoenix’s decisive showdown. Race day starts Sunday at 3 p.m. ET on NBC and Motor Racing Network, with blazing temps and low tire grip expected to define strategy.
