walnohg posted this picture at the Cohort, whic he says he found at vintag.es, a source of some previous old snapshots shown at CC. He didn’t identify it, so I did a bit of Googling. It turns out to be a homebuilt sports car, which is of course inevitable as Russia wasn’t exactly building sports cars in the 50s. Arkadij Dmitrievich Babich was the builder, and needless to say, it got a lot of attention in Russia at the time. There’s even a video of it in action.
I found this info and video at a post on kinja.com, and the source there say that it was Babich’s third home built car, and that it was powered by a 90hp 3.5 L six cylinder engine from a GAZ-12 (ZIM) limousine. Apparently Babich went on to build a lightweight tube frame for the succesful KVN2500S sports racing car, a car no one in the West was familiar with as it only raced in iron Curtain countries.
Remarkably, the Babich still exists, and will supposedly be restored “some day”.
