The Brawn GP car's chassis was designed by Honda engineers. If that team decides to go with the $30M R&D cap for 2010 in exchange for a lot fewer rules,
I think Honda can come back with a radical engine design and it'll be called Brawn Honda. This Brawn GP private team might be the start of something grand, like how
Bruce McLaren,
Frank Williams, and
Enzo Ferrari started their own F1 racing teams. No doubt Nick Fry, still the team's CEO, had exactly that evolution in mind when he agreed to name the team thus.
