1969 Hot Wheels Twin Mill

When it comes to Hot Wheels, there is nothing more iconic that the over-the-top Twin Mill. Designed by Ira Gilford, who quit his job at Chrysler to design cars for Mattel, the Twin Mill is a prime example of the kind of outlandish concepts that make Hot Wheels such a success story. A life-size, drivable replica was built in part by legendary hot rod designer Boyd Coddington with then upcoming car icon Chip Foose in charge of the build. It was finished by Barry Lobeck years later and debuted at SEMA in 2001. What the Twin Mill lacks in visibility from its detailed cabin, it makes up for in horsepower. Dual-blown Chevy 502 big blocks blast around 1,400 horses, making it one of the most powerful cars in Forza history.
