He has been formally identified as Daniel John Foale from the Kingsbridge area. His family have been informed.
The 31-year-old female driver of the red Seat Ibiza, registered to Nottingham, and a four-month-old girl, were taken by ambulance to Torbay District Hospital. The woman suffered minor injuries and the child was uninjured.
The 41-year-old female driver of the green Mitsubishi Space Star, registered to Dartmouth, and a 13-year-old boy were treated at the scene.
The road was closed for eight hours while officers from the Serious Collisions Investigation Unit carried out a thorough investigation of the scene.
