You've heard of the Flying Dutchman? Did you know he had an Alfa Romeo GTV with an extra V6 tucked in behind the seats?

Historians may recall the Alfa Romeo GTV Bi-Motore race cars, which in 1931 had two Alfa 6C straight sixes and by 1935 had two 8C straight eights — commissioned in a bid to compete with Germany's Auto Union "Silver Arrows."

Those cars were the inspiration for Stephan Lenior of Nunspeet-based Squadra Tuning to combine a 3.2-liter V6 from an Alfa Romeo 166 with this GTV's existing, front-mounted 3.0-liter V6. The ridiculously complicated build yielded a combined output of 487 hp. Of course, to make it work, he also had to figure out how to merge two 5-speed gearboxes (of Lancia Kappa 2.4 JTD spec) under the guise of a single shifter.

If there's a Nobel Prize for batshit builds, this guy should be up for it.
