The Twin Mill is largely thought of as the car that defined Hot Wheels and is so iconic that it was the first car Hot Wheels commissioned to make life size. Twin Mill has two engines, two superchargers and zero visibility. Lyons visits Action Vehicle Engineering (where these cars are maintained) and talks to Hot Wheels’ Sr. Design Manager for Die-Cast Vehicles, Bryan Benedict. Bryan lends insight into the monumental influence that the Twin Mill has had within Hot Wheels, his personal career and the car world at large. After Nicole and Bryan highlight all the full-size Twin Mill attributes, Lyons takes the temperamental, dual engine behemoth on a test drive through the desert where things get smoky.
