In the Trans-Yukon Rally Race, which is currently underway, they give a four minute window between start times for each team to space the vehicles out on the course. Each team's finish in the race is then determined by their individual time to complete the course. There are five teams that are sponsored by American motor companies. The drivers of the American teams, their current mileage into the race, and their official times at that point of the race are listed in the table below. Name Mileage Time (hours:minutes:seconds)
