Cooling electric motors is crucial for maintaining performance and longevity, especially as EVs push the boundaries of speed and power. During high-stress activities like track racing, motors can overheat, compromising their efficiency and risking damage. Monroe highlights a real-world example: the Xiaomi Sous7 Ultra—a 1500-horsepower electric vehicle—competed against a Tesla Model S Plaid. Surprisingly, despite the Xiaomi's superior power, it lost the race due to cooling issues; overheating caused performance drops, whereas Tesla's more efficient cooling allowed it to excel.

The Contrasting Approaches: GM's Simplicity vs. Tesla's Precision

Monroe's team examined motors from a GM Chevy Equinox and a Tesla Cybertruck, revealing fundamentally different engineering philosophies.
