Every Engine BANNED From Motorsport — Explained
Every Engine BANNED From Motorsport — Explained
Quick note before you watch — I had exams this week, so I couldn’t give this video the amount of time I normally do. There are a few editing mistakes here and there, but I still wanted to get the video out for you guys. Hope you enjoy the video ❤️
Some engines were so powerful, so dominant, or so controversial that motorsport's governing bodies had no choice — they had to ban them. In this video, we break down every engine officially banned or outlawed from competition, and explain exactly why the regulations had to change.
From the BMW M12/13 that reportedly produced 1,400 horsepower from a production car engine block, to the Mazda R26B rotary that won Le Mans as a farewell lap before its ban had already been announced. From the Group B rally engines that killed drivers and spectators until the entire category was shut down overnight, to the Formula One V10 spinning at 19,050 RPM — an engine the FIA decided was simply too much.
Every engine in this video was officially banned, restricted, or directly outlawed by regulation. No myths. No fan theories. Only verified history.

In 2026, Formula One is already dealing with new engine controversies — Mercedes and Red Bull found a compression ratio loophole in the new 1.6L hybrid regulations, and the FIA has been scrambling to close it mid-season. History repeats itself. Engineers find the edge, regulators draw a new line, and the cycle continues.
This video covers the engines that started that cycle — the ones that forced the rules to be rewritten permanently.
