Four Motors, One Mission chronicles the remarkable ascent of the Yangwang U9, the electric hypercar that redefined performance in the twenty-first century. From its origins within a mass-market automaker to its unveiling as a symbol of industrial precision and ambition, this book captures how a company better known for accessibility reached the summit of technological excellence. It tells the story of engineering at its most exacting-where four independent motors, predictive software, and millisecond control transformed physics into poetry. Through detailed narrative and rich technical insight, the book explores the U9's evolution: from concept sketches to production reality, from viral suspension demonstrations to record-setting track runs. It reveals how the U9's creation reshaped not only a brand but also the global conversation about what defines performance, luxury, and innovation in the electric era. This is not merely the account of a car, but of a mindset-the disciplined audacity that turns possibility into proof. The U9 stands as a milestone in the changing geography of speed: proof that world-leading performance is now as much about software, systems, and sustainability as it is about raw power. In tracing its journey, Four Motors, One Mission captures a pivotal moment in automotive history-the instant when electricity, precision, and courage aligned to create a new benchmark for what a hypercar could be.
