Black curtains surround the room that's segmented by rolling privacy screens, blocking off the business end of a European Volvo truck (is it an FH? An electric? It's hard to tell.) This is the only area trucking journalists from North America are allowed in.

Even several of the Gothenburg-based Volvo Trucks employees that are presenting haven't been allowed in this building before. But what we're here to talk about is anything but a secret.
