Everything You Want to Know About the 1975 Corvette, All in One Place.
The 1975 Chevy Corvette, along with the automotive industry as a whole, would experience a significant transformation at the onset of the new model year. Because of serious health issues and environmental contamination associated with the use of lead fuel, it was determined that the automotive industry would – and should – phase it out.
Tetraethyllead (also known as TTL, or simply “lead”) was introduced in the 1920’s as an additive to prevent fuel from auto-igniting in high compression, internal combustion engines. While the lead additives allowed engine designers to produce more powerful, higher compression engines, it also produced a dangerous neurotoxin through exhaust emissions, which resulted in many cases of acute, and widespread lead poisoning, especially in children.
Additionally, the lead component was destructive to catalytic converters, which were to become a Federally mandated requirement to aid in the control of damaging exhaust emissions.
