This edition of Drive it! takes us to the automotive past, present and future. There's the new Audi A4, and a review of BMW's electric concept cars. We also pay a nostalgic visit to the original VW Bug and its revamped successor, the New Beetle. Plus a report on a car that can influence the outcome of Formula 1 races despite not competing.
