Armored mechs erupt from racing cars on a desert battlefield

A post-apocalyptic desert battlefield where extreme mechanical power rules. Armored semi-hovering cars race across the dunes, transforming as massive mechs unfold and rise from their chassis. These scrap-built mechas launch into the sky, engaging in aerial combat above the desert, firing energy weapons, missiles, and improvised cannons. Below, engines roar and dust storms swirl, while above, metal giants clash mid-air. The machines are made from junkyard parts, rusted steel, and exposed hydraulics. The scene is chaotic, intense, and cinematic, with a gritty dystopian sci-fi aesthetic, dramatic lighting, dynamic motion, and ultra-detailed concept art quality.
