According to the story, in 1931, Tesla modified a Pierce-Arrow car in Buffalo, New York by removing the gasoline engine and replacing it with a brushless AC electric motor.
The car was claimed to have been driven for about 50 miles at speeds of up to 90 mph over an eight-day period.
[1][2] The story has been subject to debate due to the lack of physical evidence to confirm both the existence of the car and the fact that Tesla did not have a nephew named Peter Savo.
[citation needed] A number of web pages exist that perpetuate this anecdote.
[7] With the exception of these points, every other account of this purported demonstration automobile is based solely on the Peter Savo story with additional embellishments added by subsequent retellings.
