Lest we forget there's a car show going on south of the equator — ladies, don your sequined thongs and fruited headgear in honor — check out Chevrolet Prisma Y Concept, which the company unveiled at the Sao Paulo auto show in Brazil yesterday. It's another take on the 4x4 crossover genre, which seems to be quite a thing down there. Compared to Fiat's similar Adventure concept, the Prisma Y looks more like a production-ready model. Note too the similarities with the WTCC Ultra concept Chevy revealed at the Paris show. Then forget them, because you'll never see this thing in the Home Depot parking lot on any given Saturday.
