There is a new NASCAR series called the Unlimited Series, and team Fastex owner Jack Fassler has hired four racers: Mark "Charger" McCutchen, Steve "Flyer" Sharp, Carlos "Stunts" Rey, and Lyle "Collector" Owens. He fired Lyle "The Collector" Owens for disruptive racing while he seeks a contract with Fassler's nemesis, Garner Rexton, owner of Rexcor. He spies Fassler, who has finished the prototype cars. While Flyer drives his car, he loses control on the track. The series premiered 6 days after Dale Jarrett clinched the Championship at the Pennzoil 400.

Flyer manages to stop the car after losing control of it, but Jack is more concerned about letting his daughter Megan drive for the team. He finally gives her a chance reluctantly. At a banquet before the first race, Lyle challenges Mark to a race in the Rescue Racers at the quarry, and he agrees. However, the race is fixed and Charger's Rescue Racer flies off a closed road into a river.

Mark ends up in a river but was subsequently saved. He also wins the first race of the championship after a grudge match against the Collector & Megan Fassler becomes Spitfire.

Megan is badly injured in a racing accident by Rexcor's microwave technology, and Jack blames Duck, who quits. Duck joins Rexcor, but is secretly spying on Rexcor to see if they are the ones responsible. It turns out that they have the microwave technology, and Jack and Duck have to stop Rexton from frying Fastex's cars on the next race.

Megan is training in the simulator when a mysterious figure meets her and asks her to drive for him against the computer. It is really The Collector hacking in the simulator, and he hooks up the simulator to his car so Megan will be driving it in the next race. She will have to realize that it's all a trap by The Collector.

A military intelligence officer asks Flyer to destroy a chemical warfare factory while in an off-road race. Flyer must fight his way through Brock Van Leer's desert base, along with his friends, and destroy the chemicals.

Lyle Owens rigs Charger's car to go out during an off-road race in Alaska. Charger encounters an airplane crash while being stranded, and a man trapped in the airplane calls out to Charger for help. The crash site, however, is decades old and is deserted. Charger wonders if the mysterious man was his father. But in the end, Hondo Hines wins and Fastex fails to win at Alaska.

After Miles accidentally takes over a computer-controlled car and creates chaos at the Fastex headquarters, Mark banishes him from the garage and the pits. Meanwhile, Garner Rexton schemes to reprogram the computer that controls the Motorsphere so that the sphere's morphing track will attack team Fastex cars during the next race and try to destroy them. Miles and Shelby are trapped inside the Motorsphere along with team Fastex. As Fastex drivers struggle against the automated obstacles and lasers thrown at them by the Motorsphere, Miles uses his technical video game to disable the computer and save the day.

While training in an off-road area in the South American laguna, Libby Fassler has been kidnapped by some bounty hunters secretly hired by Garner Rexton. By trying to bring her to his side, Garner sends out team Rexcor to try and save her, the same thing which Fastex does and succeeds.

While training for some stunts, Carlos "Stunts" Rey jumps in partnership with a beautiful stunt driver named Eve Kildere. Stunts begins falling for Eve, unaware that she's purposefully trying to lure him away from Team Fastex as a way of repaying a debt she owes Garner Rexton. In the end, she changes her mind at the last minute while some fireworks have been prepared to be launched during a stunt made by team Fastex, to kill them. Scared, she jumps in a car but is caught by Stunts and then arrested by the police.

After two victories for Team Rexcor (after winning Secada 500 and Tundra 2000), a new race has been prepared for both teams. Meanwhile, thieves being pursued by the police hide a new guidance component stolen from the government in Team Fastex's hauler, particularly in Flyer's car. But when the thieves come back to take the component, Flyer's car has been painted in red and white for the "All-American" highway cross-country race (like the American flag). As the thieves no longer recognize the car, they use monster trucks, bulldozers, and a stolen helicopter to search for the component by destroying all cars in their way. One of the thieves tricked Hondo Hines and used his driver clothing to compete in this race as Specter of Team Rexcor.

The first season of the championship is getting to a closer end when Rexcor uses the new driver to compete against Fastex, the driver known as Kent "Demolisher" Steele. After Lyle Owens was fired and Steele hired, Fastex was also working on a "secret new weapon" for the last race: a supercar that pushes the performance envelope far beyond the team's regular cars. After the supercar lost control and disintegrated, Duck realized that the car was too hard to control for any human being, though Jack was very confident of victory. With the individual driving championship at stake, the Fastex drivers, each with an individual compulsion to win, no longer race as a team. Disunited, they fall easily as prey to "Demolisher" Steele, who wins the race by destroying all Fastex cars. Garner knows that Steele will win again, because his new driver who replaces Lyle "Collector" Owens is, in fact, a superhuman android.

With the last race of the championship at stake, team Fastex drivers manage to bury their differences and work as a team again. Together, they ask Jack about who is going to drive the new highly-experimented car, with the driver to be chosen at random. Megan and Miles tried to convince Charger not to drive the new car being afraid that they might lose him. Meanwhile, Lyle persuaded Eve Kildere from prison to use the Unlimited Series car to re-enter the last race as "The Mysterious Wild Card". He and Charger together defeat Steele (who was exposed as an android and caused Rexcor's season disqualification for cheating) as Fastex wins the championship.
