Rainer Zietlow and Derek Collins have spent the last 100 days in an all-electric ID.4 visiting more than 600 Volkswagen dealerships around the U.S. For their efforts, they’ve been rewarded with a Guinness World Record.

Their prize was awarded to them upon returning to the Volkswagen USA headquarters in Herndon, Virginia, where they ended their trip, which is now officially the longest continuous journey by a non-solar electric vehicle in a single country.

“It was great being able to share my experiences with the ID.4 with so many different people, including dealership staff, along the way,” said Zietlow. “Breaking the record is not only a testament to the reliability of the ID.4, but also to the actual readiness of the nation’s charging infrastructure.”

The trip took them more than 35,000 miles (56,327 km) and to 628 VW dealerships scattered around all 48 contiguous states. With that, they more than doubled the existing record.

“Congratulations to Rainer and Derek for setting a new world record,” said Hein Schafer, Senior Vice President of Product Marketing and Strategy, Volkswagen of America. “Their achievement is a significant recognition for the entire Volkswagen EV landscape and this tour provides further proof that the ID.4 is a very realistic and capable alternative to gasoline-powered vehicles as public EV charging stations become increasingly more available.”

Zietlow is no stranger to distance records, having previously accomplished feats such as driving from Alaska to Argentina in just 12 days or driving from Africa’s southernmost point to Europe’s northernmost point in just nine days in a VW Touareg.
