That article is from 2009, a full decade ago. It's a prime example why people are very weary when it comes to VAG announcing concept EVs. It's not a contender until I can actually purchase one.
Any car manufacturer can create a concept EV with relative ease. That's the easy part. Taking it to production (especially at scale) is the hardest part.
There's no point trying to concoct a narrative that this is all somehow vaporware. You can pre-order your VW ID Neo in 7 weeks:
