Looks like the last fuel stop and now down one lap.
36 mins to go, about 16-17 laps. If they are 9 seconds a lap quicker it'll take around 13 laps to make up the distance, if it is indeed a full lap down. I assume the M3 will not need to take on fuel.
Going to be close but I think they can do it! Dang, with no fuel problems this wouldn't even be an issue.
