Introduced in 1969, the Twin Mill was the first original Hot Wheels design toy car. A real life recreation, powered by two big block, supercharged Chevrolet V8 engines each being 8.2L, debuted at the 2001 SEMA tuning car show.
|“||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.||”|

The Twin Mill is powered by two front-mounted, supercharged Chevrolet big block 502 V8 engines that deliver a total of 1401 hp (1045 kW) and 1401 ft·lb (1900 N·m). This brings the displacement to 16.5L (16,453 cc), making the Twin Mill the car with the highest engine displacement in the Forza series.
The Twin Mill uses a rear-driving six-speed automatic transmission and has an internal speedometer with flame-styled text at 200 mph (322 km/h) and beyond. With a weight of 4696 lb (2130 kg), the Twin Mill, despite having a high-powered set of engines, has a power-to-weight ratio of 658 hp (491 kW) per tonne.
The Twin Mill accelerates from 0 to 60 mph (97 km/h) in 2.5 seconds and on to 100 mph (161 km/h) 2.8 seconds later. It reaches a top speed exceeding 229 mph (369 km/h).

The Twin Mill is among one of the fastest accelerating S1 Class cars, with 0 - 100 mph (161 km/h) occurring in 5.3 seconds, equivalent to or faster than many exotic cars. With its high-powered engines, the Twin Mill, as expected, launches off the line with strong wheelspin, which actually jeopardizes its acceleration. In terms of handling, the Twin Mill handles similarly to low-end hypercars. The Twin Mill's braking, on the other hand, is not overly efficient compared to various high-end S1 Class cars, as it requires 348.4 ft (106.2 m) to brake to a stop from 100 mph (161 km/h), which then makes it have to brake earlier than normal despite its handling capabilities. It reaches a top speed of 231 mph (372 km/h), which also makes the Twin Mill among one of the few S1 Class cars capable of exceeding 230 mph (370 km/h).
