Episode Notes

What’s the difference between a ‘Test Driver’ and a ‘Reserve Driver’? Well, who better to answer that than Cadillac Test Driver Colton Herta and Reserve Driver Zhou Guanyu?

Colton and Zhou join Christian Hewgill ahead of Cadillac’s first home race in Miami to answer your questions about Formula 1.

How does F2 compare to Colton’s previous career in IndyCar? What’s it like working with Valtteri Bottas and Sergio Perez? Who replaces a driver if they are injured or ill? How close is simulator performance to the real car? And why do drivers sometimes plunge themselves into ice baths after a race?
