History Smallest displacement car engine?

Discussion in 'The Hokey Ass Message Board' started by sgtlethargic, Jul 1, 2023.

  1. Let's figure out what the smallest displacement (1965 or earlier) car engine was.

    I'll start with the 1960 Falcon 144:

    The first few Austin 7s were 42 cu. in. That was up to 45½ cu. in. by the time American Austins and Bantams etc. happened.

    Very small engines weren't that uncommon in Europe pre-'65:
    Citroën 2CV, 1948 on: 26 cu. in.
    Fiat 500, 1936-55: 35 cu.in.
    Fiat 500, 1957-75: 30½ cu. in.
    Renault 4CV, 1947-61: 45½ cu. in.
    NSU Prinz, 1958-62: 35½ cu. in.
    BMW Isetta, 1953-62: 14½ cu. in.
    BMW 600, 1957-59: 35½ cu. in.
    Messerschmitt KR175, 1953-55: 10½ cu. in.

    This is just off the top of my head. All these cars were exported to the USA in the '50s. They might have been curiosities, but they were a presence — enough so for hot rodders to discover Topolino and Bantam bodies.

    Peel p50 2.9 cubuc inches "Capable of a top speed of 38 mph, the P50 features a 49-cc 4.5-horsepower single-cylinder two-stroke Zweirad Union engine mated to a three-speed gearbox. The Peel P50 has no reverse gear, simply a handle on the rear to enable the driver to pick up the car and maneuver it as required!"

  13. I think I know what you're asking for, if so I think you were on the right track with the Kent motor.

    I was looking at a Lloyd on Craigslist the other day that had a 2 cylinder engine, don’t know how big but it didn’t even look like an engine.
