In the past, Porsche's factory team used Volkswagen Transporter vans for logistics, referring to it as a Bulli - a portmanteau of Bus and Lieferwagen (delivery van).
Porsche envisioned a contemporary reimagining called Vision Renndienst, which was used in the reveal of the Porsche Vision 357 concept to mark the company's 75th anniversary.
As Porsche focuses on electric cars, the ID.Buzz's highly practical MEB platform made the most sense, thanks to its skateboard architecture which frees up space within the cabin.
Even back in the day, the Transporter was chosen for its T1 platform, which was extremely practical and made for a roomy and comfortable team mover and occasional RV.
Porsche plans to use a variety of electric buses as shuttles around its upcoming events, though we doubt the Renndienst or any other such vehicle will be used at events like Le Mans.
