The fastest cars ever made are subject to some debate, as speed records are constantly being challenged and broken.
However, as of my knowledge cutoff date of 2021, the record for the fastest production car is held by the Koenigsegg Agera RS, which achieved a top speed of 277.9 mph (447.6 km/h) in 2017.
The title of the fastest street-legal production car goes to the Bugatti Chiron Super Sport 300+, which reached a top speed of 304.77 mph (489.87 km/h) in 2019.
The 2022 Dodge Challenger is pretty fast for what it is!
It’s important to note that these records are held by cars that were designed and built specifically for speed, and they are not road-friendly or suitable for everyday use.
