Predecessor to the modern minivan, the DKW F800 was woefully underpowered (20hp! Upgraded through the addition of another cylinder to 32!), featured a flat load-floor due to its front-drive configuration, and was built from 1949 to 1962. We'll take ours mid-engined and RWD'd, thanks. An Audi R8 drivetrain seems as if it would do the trick (after all, one must keep with the Auto Union theme now, mustn't one?) Yes, that might be the ultimate sleeper death-hoon van to beat all sleeper death-hoon vans. It just might.
