Porsche isn't just fast at Autodromo Hermanos Rodriguez. The high-altitude circuit exposes which teams actually understand their powertrains versus which ones are running software patches. Here's where the 99X Electric's efficiency advantage isn't marketing—it's physics.

Researchers have developed a conductive windshield coating that melts ice in seconds using electrical resistance—the kind of practical engineering that actually solves a problem instead of creating new ones. The tech uses a transparent conductive layer, meaning no visible heating elements or visibility compromise. It's the kind of solution that makes you wonder why OEMs haven't already baked this into every production windshield.

Audi shakes down its new F1 chassis at Barcelona this week, marking the German manufacturer's formal entry into the sport after years of acquisition and reorganization. The shakedown is the first time the Sauber-based platform will turn a wheel under Audi power—a crucial moment to validate months of bench work before pre-season testing begins in earnest. How the PU behaves under real track load will tell you everything about whether this $500M commitment actually works.
