Volkswagen has been trying to trumpet its green credentials for quite a while now, with three different I.D. concepts been shown in the last year itself. And now, the company has teased yet another new concept which will join the I.D. Buzz electric van, I.D. Crozz and Crozz II SUVs. The 2018 I.D. Vizzion concept is different from the other cars in the series though - it is a fully autonomous car!
