As we explore new forms of energy and propulsion, the lessons learned from these dangerous fuels remain relevant, guiding us toward a safer, more sustainable future.
When it comes to running an engine, it is essential that the fuel is flammable. However, this same characteristic that drives innovation in vehicles it also brings with it significant dangers, both for traditional fuels and for the electricity used in electric cars.
Among the various fuels used throughout history, some have stood out not only for their exceptional power capabilities, but also for their extreme health and safety risks. Let's explore some of these fuels, illustrating their benefits, dangers and some of their fascinating history.
Methanol: a double-edged fuel
Methanol, used since Ancient Egypt to embalm bodies, shows the duality of being extremely useful and dangerously toxic. Despite its usefulness as an alternative fuel, especially after the 1973 oil crisis, methanol vapors and prolonged contact with it can be fatal, causing problems such as blindness and death. Still, its use in racing and its cooling effect that allows higher compression rates highlight its usefulness, despite the risks.

Lead tetraethyl
Discovered in 1916, lead tetraethyl was a revolutionary additive that improved the quality of gasoline and increased vehicle power. However, its harmful effects did not take long to manifest, causing serious illnesses and significant environmental impacts. The battle against its use led to the ban of leaded gasoline in the United States in 1970, marking an important step in raising awareness about the dangers of certain additives.
Nitromethane – powerful fuels
Nitromethane is another fuel that provides exceptional power for engines, especially in drag racing. Its rich oxygen content allows for more efficient combustion, but its high explosiveness and production cost make it impractical for use in common vehicles. The mixing of nitromethane with hydrazine in the 60s highlighted the relentless pursuit of performance, even at the cost of extreme safety and health risks.
Hydrazine: extremely powerful, dangerously toxic
Hydrazine, a fuel used in both rockets and some extreme forms of drag racing, is a notorious example of a highly effective and dangerously toxic compound. Its vapors can cause severe damage to the lungs and cause edema, making handling it a task for highly trained and equipped professionals.
The journey through the most dangerous fuels used in vehicles throughout history It reminds us of the fine line between pursuing innovation and ensuring safety and health. While these fuels have opened new avenues for performance and effectiveness, they also underscore the importance of moving forward with caution, respecting the limits imposed by public health and environmental safety.
