Joe's Drive-In street cars

The Joe's Drive-In street cars are background vehicles featured in the 2008 Speed Racer film.

Technical Details
Seeing as they have the same body shape as the Flying Foxes street cars, they very likely use the Okamoto Roadster BXX component core body with a Ki-Goi tapering monocoque.

Like most other rally cars participating in the Crucible, it is equipped with illegal modifications. In the scene where the camera shows X-ray views of the cars that possessed illegal weapons, one of the Joe's Drive-In cars is shown to have a Sempre-Fi Articulating Scissorator.

Background
These cars sponsored by Joe's Drive-In appear in the Casa Cristo 5000 race. All of their liveries are similar to one another, with the exception of one car which has a darker color compared to the other two. Each of them also have hexagonal shapes of different colors on their bonnet.

Orange Car (Yellow Hexagons)
The orange car with yellow hexagons is first seen on the eighth row, behind another Joe's Drive-In car. The driver is a female racer with a dark helmet. A scene where an x-ray view of the car's interior is shown, revealing that it is equipped with a Scissorator. This weapon, however, would end up not being used on-screen. The car is next seen on the right lane of the Muqranna, and is assumed to have finished the First Leg together with its teammates.

Orange Car (Black Hexagons)
The orange car with black hexagons is on the seventh row at the start, in front of another Joe's Drive-In car. The driver wears an Infernal Oil helmet. It is not properly seen until the Muqranna, where it jumps over a destroyed Mutafed car. It is later seen exiting it. It is assumed to have finished the First Leg.

Dark Orange Car
The dark orange car with yellow and black hexagons is on the third row at the start, being the closest one to the front, and very far from its teammates. The driver wears an Infernal Oil helmet. It is seen taking off with the other cars at the start and entering the Muqranna, but is not seen again until the end of the First Leg.
