Sempre Fi-Ber street cars

The Sempre Fi-ber Street cars are the vehicles fielded by Sempre Fi-Ber in the Casa Cristo 5000 from the Speed Racer film.

Technical Details
These cars feature a factory-standard Kawarimono chassis. The body shell of the vehicle is broad and low-slung, following the contours of a modern military helmet.

However, like most rally cars competing in the race, it is armed with illegal weapon modifications. The Sempre Fi-Ber Street car comes equipped with a titanium Sempre-Fi Articulating Scissorator, as well as a Bo-Bae R124 Plasma Cannon, also known as the "goo gun".

Background
These cars are driven by three military-themed drivers from the Sempre Fi-Ber team. The three soldiers appear clearly in a scene where they are bribed with money by Cruncher Block's goons. Car #42 is driven by the leader of the soldiers, Colonel Colon, who can be seen in the center of that scene; car #61 is driven by the soldier to the left of Colon; and car #75 is driven by the soldier to his right.

#42
Starting on the eighth row is the leading Sempre Fi-Ber car, driven by Colonel Colon. What distinguishes him from his teammates is the three stripes on his car being red rather than white or orange. His number is also printed in red, unlike his teammates. He gets a good start, but isn't seen in the Muqranna.

He can be seen leading the Sempre Fi-Ber team into the Zunubian Desert. In the desert, he gets shunted off course and flips. Thankfully for him, he regroups and stays in the race. His luck gets worse however, as he gets spun out by the Thor-Axine team. He comes to a complete stop and Scooter Dickey on the Yen-Che car #96 drives right into him. Both cars recover and stay in the race. Colon then attacks Taejo Togokhan, and they make it their new mission to eliminate him from the race. On the dune leaps, he shunts Taejo once again in midair. Together with car #61, he puts Taejo into a spin, and they continue to hit him. In one of their attacks, they try to enclose Taejo, but he brakes and it results in #42 and #61 bashing into one another. In the dust clouds, the Sempre Fi-Ber team continues to attack Taejo, but he fights back and shunts the colonel. His race ends when Gothorm tries to kamikaze Racer X, but instead lands on Colon.

#61
Starting on the seventh row is car #61. Driving for Sempre Fi-Ber, he is one of Colonel Colon's men. At the start, the soldier can be seen making contact with Gus Gustaferson in car #67. He doesn’t show up in the Muqranna, but on the path to the desert he can be seen.

In the desert, he gets punted by Scooter on the Yen-Che car #96. He goes flying across the dune, which causes Racer X to go off-road to avoid him. Despite this beating, he still stays in the race. After regrouping, the team decides to attack Taejo Togokahn. In one of their maneuvers they miss Taejo, resulting in friendly fire. Car #61 accidentally slams Colon. In the dust clouds, he shunts Taejo across to his teammate. Out of the dust clouds, the troops become separated, and that was when they begin to be picked off. Racer X takes a large leap and bombs car #61, sending him spinning so hard that he gets knocked out of the race.

#75
At the start, car #75 can be seen in the second row next to Gothorm. After the race starts, he takes the extra left lane in the Muqranna. He sees Speed to his right, so he cuts him off by cutting into the standard left lane. After cutting Speed off, he quickly gets away from him.

We can see him drifting alongside the Zunubia mountains behind the Flying Foxes Freight team. In the early half of the desert, car #75 can be seen in 4th place. In the desert, he makes his attack on Taejo Togokahn together with his team. They fought as they hopped dunes, with car #75 slamming into Taejo from his blindside. He attacks Taejo together with his teammates, being the third to do so. In retaliation, Speed slams him when he comes back. During the continuing fight, he continued to attack Taejo. However, he is used as a human shield for Taejo by Speed, and becomes a passenger after Speed does a rear single set jump into a flying kick. This move results in his car being catapulted and destroyed after several violent rolls, effectively eliminating him from the race.
