Then comes the North American version of the Up!, which made its debut at the 2007 Frankfurt show. VW is rumored to be considering a Beetle-style version of the rear-engine, monobox/hatchback concept. Makes sense, since American consumers remain more nostalgic for the Beetle than they are practical about boxy hatchbacks. What’s more, J Mays designed his Concept 1, for the 1994 Detroit show, to be built on the smaller Polo platform, not the Golf platform, so we know that adaptation of the New Beetle style to a smaller car is far from impossible.
