To forever put forth the collected might of the Soviet into the history of speed and worker achievement came the mighty Zvezda-1, which means star in Russian. The two-stroke two-cylinder engine at the heart of this 1948 streamliner featured something known as undoubled pistons. This undoubling somehow employed one combustion chamber for two pistons and created a mind-bending 42 horsepower. The Zvezda-1 was not so speedy in itself, yet begat the 54 horsepower Zvezda-6!
