Some two-stroke cars in the 1950s could actually run in reverse. Engines like those in the Saab 93 could restart backwards, letting the car drive without a reverse gear. Drivers sometimes stalled and accidentally relaunched in reverse, shooting backward unexpectedly. It was both ingenious and terrifying, proof that creative engineering sometimes came with quirky dangers. | Auto Viral

The engine that ran backwards. Did you know some engines literally ran in reverse? Certain two-stroke engines in small cars and scooters could run forward or backward, depending on ignition timing. This clever trick meant no need for a reverse gear. The engine just restarted the other way. The Saab 93 rally car even used it, though drivers sometimes stalled and relaunched in reverse by accident. The design worked because two-strokes fire every revolution, making them symmetrical. It was ingeniou
