I wonder how much of a budget Actas had to work with. They are certainly stretching the seiyuu. Sodoko's team are all voiced by the same person.
In Anteater team, only Nekota is credited in the ending and I'm very sure that Momoga is Takahashi Mikako (Yuzu). And I think one of the automobile club members is KitaEri.
Edit : OK, they've updated the official site. The lion team does indeed have KitaEri and also Kanemoto Hisako (Katyusha)
Edit 2 : And the KitaEri character Tsuchiya is probably named after Tsuchiya Keiichi (aka the Drift King). Lots of drift talk from her
And the others are named after racing drivers
