In the United States, the 1926 racing scene was dominated by the AAA National Championship Trail, a grueling series of 24 championship races (plus several non-championship events) held mostly on high-banked wooden board ovals, with the Indianapolis 500 as the crown jewel. Harry Hartz claimed the national drivers’ title, narrowly beating Frank Lockhart (who also secured five wins, including a dramatic rain-shortened Indianapolis 500 at 95.904 mph average—the first Indy 500 halted early by weather). Miller-powered cars (including innovative front-wheel-drive variants) prevailed amid high speeds (often 120–130 mph on boards), mechanical attrition, and risks like splintering surfaces. Key tracks included Atlantic City (debut), Altoona, Charlotte, Rockingham, and Culver City, highlighting the peak of America’s roaring ’20s board-track era.
Internationally, the AIACR World Manufacturers’ Championship (the second year of Grand Prix racing’s world title) expanded to five rounds under the new 1.5-litre supercharged formula, with Bugatti (and its dominant Type 35/39A) securing the manufacturers’ crown through consistent wins by drivers like Meo Costantini and others. Bugatti triumphed in key events such as the French Grand Prix and others, outpacing sporadic efforts from Delage and Talbot and Alfa Romeo’s withdrawal due to costs. The season featured classics like the French GP at Miramas (won by Jules Goux in a Bugatti), the Italian GP at Monza, and the inaugural British Grand Prix at Brooklands, emphasizing European factory teams’ technological battles amid economic pressures and the formula’s shift toward lighter, supercharged machines.
