Sempre Fi-Ber street cars

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

Technical Details
These cars feature a factory-standard Kawarimono chassis, nothing too special ("Booooring," as the narrator for the Supercharged featurette puts it). 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".

#75
The leading car of the Sempre Fi-Ber team, driven by Colonel Colon. At the start, Colon takes a dive up the inside of Gothorm Danneskjold. Colon can be seen taking 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 the Colonel drifting alongside the mountains of Zanubia behind the Flying Foxes team. In the early half of the desert, Colonel can be seen in 4th place. In the desert, the Colonel guides his team and makes their attack on Taejo Togokhan. They can be seen shunting back and forth. They then fought as they hopped dunes, with Colon slamming into Taejo from his blindside. Colon has Taejo double-teamed, and then shunts him right after. In retaliation, Speed slams the lights out of the Colonel when he comes back. During the continuing fight, Colon continued to attack Taejo. This bites him in the end though, as 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 Colon's car being catapulted and destroyed after several violent rolls, effectively eliminating him from the race.

#61
Starting on the seventh row is car #61. Driving for Sempre Fi-Ber, is one of Colonel Colon’s men. At the start, the soldier can be seen making contact with Gothorm 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 car #96. He goes flying across the dune, which causes Racer X to go offroad 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 his own teammate in car #42. 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 totally bombs car #61, sending him spinning so hard that he could not regain control. He got knocked so hard he was out of the race.

#42
Starting on the eighth row is car #42. The last of Colonel Colon’s goons, this driver is sponsored by Sempre Fi-Ber. What distinguishes him from his teammates is that his three stripes are 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 Zanubian Desert. In the desert, he gets shunted off course and flips. Thankfully for him, he regroups and stays in the race. His luck only gets worse, as he gets spun out by the Thor-Axine team. He comes to a complete stop and car #96 drives right into him. Both cars recover and stay in the race. Car #42 then attacked 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 bully Taejo. 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 plays pattycake with Taejo, but he fights back and shunts #42. His race ends when Gothorm tries to kamikaze Racer X, but instead lands on Car #42. Tough break!

Trivia
