Volkswagen is close to greenlighting its Microbus-inspired ID Buzz concept, with public reaction set to determine whether it goes into production.

"The concept has been well-received in the US and Europe," said design chief Klaus Bischoff, "but the missing link is China. From the business case point of view it’s quite an investment – it needs a global green light. In the meantime, it’s thumbs up."

Bischoff admitted that the design of the ID Buzz, which is the same length as a long-wheelbase Caravelle, is currently being worked on. "It’s more than a skin, and more than a show car," he added. "Maybe it will shrink a little, but inside it is much bigger."

The ID Buzz is the third Microbus concept, but the previous two never made production. "I've tried quite a bit to bring this [the Microbus] to life," Bischoff said. "This is the final temptation." 

The Buzz will be followed by an electric SUV concept for the Shanghai Motor Show, followed by a saloon concept later this year. The SUV will look "non-aggressive but self-confident," according to Bischoff, while a "surprise" is promised for the saloon, which apparently prompted 'wows' from colleagues on seeing it for the first time.
