VP Racing Fuels' The Mad Scientist

The Mad Scientist (sometimes referred to as the "VP Racing Fuels The Mad Scientist" or just "Mad Scientist") is a Cadillac Escalade monster truck owned by FELD. It is driven by Lee O'Donnell and it first debuted in Charlotte, NC, in 2016. It is sponsored by VP Racing Fuels.

The truck became known to complete the first ever Frontflip, that lead Lee to win the Freestyle Championship, in the Monster Jam World Finals 18. It became the first ever full front flip to be executed during competition and the second after Tom Meents performed the stunt as an exhibition during the East Rutherford show in 2015. In 2018, O'Donnell will once again be competing at the Monster Jam World Finals 19 in the truck after earning an automatic invite from getting first in Stadium Championship Series 4 on March 4, 2018.

Trivia
The Mad Scientist Character, as seen on the side of the truck, is inspired by the look of Danny Elfman in his hit song "Weird Science", which also happens to be the theme song used by Mad Scientist.
