For one year I drove E-Touran with a 24 kWh battery pack over a distance of 15000 km. A pack that small meant I had to stop and recharge every 80 km. Upgrading to 40 kWh will double that AND give me better charging speed.

In the previous video I planned my air-traffic-free journey to the UK and Ireland. Here is how it went plus what I did there and who I met.
Summary:
- The journey from Kassel to London was planned to take 9 hours and took 11 because of people of train tracks. It cost 95€ as planned.
- The journey from Cork/Ireland back to Kassel was planned to take 33 hours and it did. It was planned to cost 358€ and cost 382€ including one missed and double paid ferry and 1st class from London to Kassel
