We tell racing stories and leave out the boring parts. Ross Bentley is a former IndyCar driver and a world-renowned performance coach and author. Jeff Braun is a champion race engineer. Sam Smith is an award-winning journalist and a former executive editor of Road & Track magazine. Together, we explore the emotion at the heart of the machine.
