The Volkswagen Transporter, based on the Volkswagen Group's T platform, now in its fifth generation, refers to a series of vans produced over 60 years and marketed worldwide. The T series is now considered an official Volkswagen Group automotive platform, and generations are sequentially named T1, T2, T3, T4 and T5. Pre-dating the T platform designations, the first three generations were named Type 2, indicating their relative position to the Type 1, or Beetle. As part of the T platform, the first three generations are retroactively named T1, T2 and T3.
