In Infected Mode, the racer in last place gets infected at regular intervals. Infected racers have a timer and are visually rendered green. When the timer runs out, the infected racer explodes, loses some time and then gets cured. All infected racers have infinite Nitro. Hit other racers to infect them and to gain extra time on the infected timer. Your goal is to cross the finish line in the first, second or third position to get 3, 2 or 1 Stars respectively.
