Jack Brabham to this day remains the only person to win an F1 championship driving a car with his own name on it. That happened way back in 1966, but Brabham was a successful operation throughout the 1980s. The Brabham Automotive name was registered two years ago in Britain, at which time David said he was keen "to see the name back on track."
So far, there's little more than a logo and a website to go along with the announcement. But with such storied roots, we'll be keeping an eye on Brabham Automotive closely.
