Volkswagen has unveiled the new seventh-generation Golf in Berlin, 36 years after the original model was first released. As expected the Mk7 is a further evolution of the Golf lineage, adding what appears to be an extra layer of precision to its surfacing and graphics. New production techniques helped the design team reduce its weight by 100kg, and at 4,255mm long the new model is 56mm longer than its predecessor, with a 59mm longer wheelbase of 2,637mm and it is also 13mm wider, at 1,799mm, and 28mm lower at 1,452mm.
