Maybe one of the coolest things about the Can-Am series is that it encouraged aspiring car builders, drivers, and team owners to dream up some frankly ridiculous shit and just see what happened. These one-offs are called “specials,” and they are absurd.

Like Mac’s IT Special, which was powered by four 110-bhp two-stroke motorcycle engines — one at each wheel. A clever idea, maybe, but it only appeared at a single race.

There was also the AVS Shadow, which looked like it combined a drag racer with a sports car, and the Honker II, which looked like a designer’s nightmare come to life. The revival of the Can-Am series also brought with it the Adams Escort “Pontoon” car, featured in the video on this slide. Wild.
