Since the early days of the automobile, cars have been predominantly powered by engines with an even number of cylinders. From the earliest four cylinders to the Veyron's W16, most of the most famous automotive engines have been built with an amount of cylinders divisible by two.
This weekend, we want to take a look at the other cars, the ones powered by 1, 3, 5 or some other odd amount of cylinders. While your Chevy with no compression in one cylinder doesn't count we are expanding the choice to any road legal vehicles with more than two wheels because it's a fairly small pool to pick from. What is your favorite vehicle with an odd number of cylinders?
My pick for this one is the Messerschmitt KR200. Built during the height of Microcar popularity in the 1950s and 1960s, these tiny tandem seat German cars were powered by a 191cc Fichtel & Sachs air-cooled single cylinder two-stroke engine. Power output was around 10 horsepower and was good for getting the car somewhere into the mid 50 mph range for anyone who dared.
