Downforce: Danger Circuit, an expansion for Downforce, consists of two new tracks on a double-sided game board as well as six new racer powers to shuffle with those in the base game. These race powers are: Tough - On any player's turn, move 2 additional spaces when your car ends its movement next to a rumble strip (red-and-white). Bold - On your turn, if your car would move 1 or 2 spaces, move it 3 spaces instead. Defensive - If none of your cars move on your turn, move one of your cars 3 spaces. Reckless - On your turn, if your car moves diagonally between two adjacent cars, move it 2 additional spaces. Experienced - If any car starts its movement directly ahead of your car, move your car into the space they moved out of. Ambitious - On any player's turn, if your car crosses a betting line, move it 2 additional spaces.
