That comes despite the rival Shell V-Power Racing Team, whose drivers are Anton De Pasquale and Will Davison, being regarded as the championship's most popular team – more than five percent clear of van Gisbergen's Red Bull Ampol Racing.
The Kiwi ace did enjoy the most dominant season of his career in 2021, winning 14 of 30 races and sealing the title with a round to spare.
Van Gisbergen had ranked third in the 2020 edition of the survey, behind runaway winner Scott McLaughlin and David Reynolds.
His nearest challenger in the 2021 survey, where fans were asked to nominate their favourite Supercars driver, was Chaz Mostert (10.68 percent).
Not far behind was De Pasquale (8.57 percent), now retired seven-time champion Jamie Whincup (8.38 percent), Cameron Waters (7.57 percent), Reynolds (7.10 percent) and Will Davison (5.05 percent).
