The Honda RA106 (originally known as the BAR 008){{cite web|url=http://www.f1-forecast.com/pdf/F1-Files/Honda/F1-SP2e_all.pdf|title=Honda's Third Formula One Era|website=F1-forecast.com|access-date=29 September 2022}} was the car with which the Honda team competed in the {{F1|2006}} Formula One season. It was driven by Rubens Barrichello, who joined from Ferrari, and Jenson Button, who had spent three seasons with the team as British American Racing. The year marked the first time Honda had competed as a full team since {{F1|1968}}; since then it had only competed as an engine supplier until taking over BAR completely in late {{F1|2005}}.
