This model is inspired by the Mercedes Benz T80. The T80's inception began in 1937 when Ferdinand Porsche attempted to design a car with a maximum speed of 373 MPH. Bannarit's model pays tribute to this goal by modeling the extra wheels, outer frame and inverted V12 enginge which was derived from a DB 601 aircraft engine.
