>>28459727>no independent verification, assholes from Callaway took a grain '80s photo of a digital display and claimed they did 254 MPHThat's just how top speed claims were done back in the 1980s. I shit you not, there is no independent record of a Ferrari F40 doing more than 200mph in 1987 but Ferrari themselves claim the car can do it.
What was Ferrari's proof? Their word. I kid you not, Ferrari didn't actually provide proof to their claim, they just said it could do 200.
In 1991 Road & Track tested the top speed of the F40 and it topped at 196. However despite this, Ferrari still claims the F40 did 200+.
So yeah just common practice for companies to make up claims of top speed.
