2008 film
The Mach 4 was featured in the film as Rex Racer's car for professional-level races prior to becoming a cheating driver for Uniron and eventually faking his death in the Casa Cristo 5000. It is a single-seated race car like the Mach 6, but is red and the bodywork resembles the Mach 5. It has a white version of the distincive 'M', along with its racing number also in white surounded by a white circle. It has tailfins like the Mach 5, but there is also a third central fin at the back, all connected by a single wing to form a spoiler. The rear fenders also feature what appear to be air intakes or ground effect channels. Not much else is known about this vehicle, except for the fact that it has a front-wheel drive layout, indicating that it is not a T-180 like the Mach 6, and is part of an older generation of race cars. Added to that, the rear wheels are fixed but also feature a joint system somewhat resembling that of the T-180.
