When you see a concept car drive onto the stage at an auto show, don’t be fooled into thinking it’s what you’ll drive out of the dealer a couple of years later.

We got to drive the Volkswagen ID Buzz all-electric Microbus concept car Saturday for a couple of miles along the oceanside road outside Monterey, California.

Our drive in the ID Buzz concept was powered by a battery pack and single electric motor from the current Volkswagen e-Golf, and the vehicle was firmly limited to 25 mph.

That’s because its custom-fabricated, pale gray Hankook tires aren’t intended for highway use, nor was the rest of the very carefully hand-built prototype.

And one result of it being a prototype is that it was stiffly sprung, with fairly abrupt brakes, numerous creaks and groans, and a complete lack of regenerative braking.

None of which mattered in the slightest.

We took away two impressions from our time with the ID Buzz concept.

First, it’s just incredibly spacious inside for a 16-foot-long vehicle destined to be built on VW’s future MEB electric-car architecture, whose first use will be in a compact five-door hatchback coming in 2020.

Second, the thing is just amazingly, astoundingly popular, gathering crowds and random passers-by who stopped to snap photos and followed the vehicle into the hidden, secluded coastal parking lot where it was being photographed.

Volkswagen cleverly hired a fleet of historic split-window Microbuses, from 1967 and earlier, to ferry executives and journalists around Monterey during the weekend leading up to the Pebble Beach Concours d’Elegance.

The allure of the old Microbuses, and the new ID Buzz on test drives along the beachfront road, was immediately evident through the weekend.

Passers-by spun around to watch as soon as they heard the distinctive air-cooled engine sound, giving us the thumbs-up, taking quick cellphone pictures and selfies whenever the old Microbuses parked or stopped in traffic.
