For years, Volkswagen has teased retro microbus concepts with no intent to put them into production. But the teases are over. VW just announced that it's definitely going to put an all-electric microbus, the I.D. Buzz, into production in 2022. The I.D. Buzz's concept form was shown earlier this year at the Detroit Auto Show, but we production were thin. Then media reports suggested that VW brand chief Herbert Diess was actually pushing to get the I.D. Buzz into production. Apparently, Diess got his way.The I.D. Buzz will ride on Volkswagen's new modular electric-car platform (dubbed MEB), that made its debut at CES in January 2016. This platform, which is set to make its production-car debut in the I.D. hatchback in 2020, integrates its battery in the floorpan, just like a Tesla. The I.D. Buzz will also get optional all-wheel drive, with electric motors at the front and rear axles.It's this clever packaging that allows the Buzz to exist at all. With all of its drivetrain components mounted low in the chassis, VW is free to make a vehicle with very short overhangs and an incredibly spacious interior, just like the original. And unlike the original, this one will meet modern crash safety standards — something VW couldn't do with a modern, internal-combustion powered Bus.VW says the Buzz has the exterior dimensions of a compact cargo van on the outside while offering the interior space of a large SUV. And speaking of cargo, VW will make delivery van version of the I.D. Buzz.When the I.D. Buzz reaches production, it should feature reconfigurable seating like the concept we saw earlier this year and it will offer Level 3 autonomous driving. That's not full autonomy as it requires the human behind the driver's seat to pay attention, but the I.D. Buzz will handling steering, braking, and acceleration on its own in certain scenarios.Expect to see the I.D. Buzz in US dealers sometime in 2022, shortly after the I.D. hatchback hits the market.
