Test case: Hans Ove got 13.3% longer range in his VW ID.4 with Airtwister

Hans Ove and his family love to go camping, and this summer they went to Lake Garda in Italy. They drove their VW ID.4 with a light caravan on the hook, but range was a concern. Electric cars use more electricity when towing a trailer or caravan, which means more charging stops along the way.

To optimize aerodynamics, Hans Ove fitted Airtwister to his VW ID.4 before departure. The result? A 13.3% longer range compared to their previous trips without Airtwister. This meant fewer charging times, less waiting at charging stations and a more relaxing drive through Europe.

Hans Ove also noticed another major advantage:

“We got further on a charge, and the car wasn’t as sensitive to wind. The biggest difference was actually when we passed an oncoming truck on the highway.”¨ Says Hans-Ove

Why did Airtwister work?

✅ Reduced air resistance: Airtwister optimizes the car's aerodynamics, which lowers energy consumption.
✅ Less turbulence: Less wind resistance around the caravan provides a more stable ride.
✅ Increased efficiency: VW ID.4 could drive longer on the same charge.

Hans Ove is now convinced that Airtwister is a must-have for electric car owners who want maximum range – especially when driving with a caravan or trailer.
