Volkswagen wowed the crowds with the Bulli concept, and now it will become a production car, probably going on sale in 18 months. It won't be electric, at least not at first. I think we can expect the Jetta's engines - a gasoline I4 and a turbo diesel I4 - to power this very cute homage to VWs air-cooled past. It will be built alongside the Jetta in VWs plant outside of Puebla, Mexico.
