3) 1988 WRC Toyota Celica GT-Four A Clever Trick That Led to a Ban
Toyota entered the World Rally Championship (WRC) in 1988 with the Celica GT-Four, a car designed to compete against the best rally machines of its time.
It didn’t take long for Toyota to achieve success, as the Celica won its first race in 1989 at the Australian Rally. This victory marked the beginning of an impressive era for Toyota in rally racing.
As the years passed, rally cars became more powerful and faster, raising safety concerns for both drivers and spectators. Unlike track racing, rally events took place on public roads, where fans stood dangerously close to speeding cars.
The Fédération Internationale de l’Automobile (FIA), the governing body of motorsports, decided to impose new rules to slow the cars down.
In 1995, the FIA required all turbocharged rally cars to use restrictor plates in their turbochargers. These plates were designed to limit airflow, reducing the engine’s power output and making the cars slightly slower. Toyota, however, found a way to bypass this rule without getting caught at first.
Toyota’s engineers developed a clever system that allowed the restrictor plate to move out of the way as the car gained speed. This meant that while the car appeared to follow the regulations during inspections, it was actually producing more power than allowed during races. The trick gave Toyota a significant advantage over its competitors.
2) 1970 Chaparral 2J A Groundbreaking Car That Got Banned
The 1970 Chaparral 2J was one of the most innovative cars ever created, designed by the legendary Jim Hall. Known for his out-of-the-box thinking, Hall pushed the boundaries of car design, and the 2J was no exception. It featured two fans powered by a snow blower engine, which were used to create an enormous amount of downforce.
This fan system sucked the car down to the ground, which gave the 2J incredible grip on the track. The idea was that the more downforce the car generated, the more control the driver would have, especially when cornering at high speeds. Even at low speeds, the fans worked to keep the car stable and stuck to the road.
However, despite the 2J’s advanced technology, it never won a race. Mechanical problems and other issues held it back from reaching its full potential.
Still, the innovative fan system caught the attention of racing officials. The enormous downforce generated by the fans gave the 2J such a competitive advantage that it was deemed unfair.
Before the 2J could even show what it was truly capable of, the governing body banned the fan system. They felt that it was too much of an advantage and would give Chaparral an unfair edge over other teams.
This early ban ended the Chaparral 2J’s promising career before it could reach its full potential in racing.
The Chaparral 2J remains one of the most iconic and controversial race cars in history. Although it never had the chance to fully demonstrate its capabilities, it showcased the brilliance of Jim Hall and his unconventional approach to racing. The 2J’s fan system would inspire future designs, but it would never race again.
