Unfortunately the series was unable to earn much attention from European sportscar teams, especially since the final FIA Sportscar Championship and FIA GT Championship series used similar cars, but different rules which would require teams to modify their cars or buy new cars to comply with ELMS rules. This means that the car count for the 2001 season was small. For the ELMS events that included ALMS teams, very few teams actually bothered to make the trip across the Atlantic to participate in races that appeared to have very few serious competitors. Of the ALMS teams that did race, nearly all were factory backed squads that had the money to spend on transporting their equipment to Europe. Thus the entry lists for each race fell from 25 at the beginning of the season to a mere 14 at season's end, with some classes only having one or two competitors.
