Smoke Screen (en Inglés) - Alberto Ayala;David Miller

A Global Lie. Relentless Pressure. And the California Public Servants Who Stood Up for the Truth.

In Smoke Screen, Dr. Alberto Ayala - the former California Air Resources Board executive who led the technical investigation that unraveled Volkswagen’s "clean diesel" myth - reveals for the first time the inside story of the global scandal that changed the auto industry forever.

Told from inside the closed-door laboratories and conference rooms where the truth was fought for and defended, Smoke Screen traces three critical decisions that turned a quiet research study into a billion-dollar reckoning. From the first spark of curiosity in a Riverside café to the explosive confession that shook Wolfsburg, Ayala’s account exposes how data, integrity, and persistence triumphed over corporate deceit.

Follow the Data. Expose the Design.

Smoke Screen is the untold inside story of how a dedicated team of California regulators, engineers, and scientists uncovered the world’s biggest automotive deception. When Volkswagen’s "clean diesel" promise began to crumble, these public servants faced immense corporate pressure and political headwinds. Against all odds, they followed the data, exposed the lie, and ignited a global reckoning that forever changed the fight for clean air and corporate accountability.
