Imagine you’re watching the race on a weekend as usual, and then suddenly, you spot a six-wheeled car in F1. Well, that’s exactly what happened in 1975 when Tyrrell P34, known as Project 34, was revealed at the Spanish Grand Prix. This moment still stands as one of the most radical and memorable designs in F1 history, developed by the Tyrrell Racing Organization under the direction of chief designer Derek Gardner.
Why Was A Six-Wheeled Car In F1 Introduced?
The P34 was the only six-wheeled car in F1. The motivation behind this not-so-authentic car came from Gardner’s idea to push the boundaries of F1 regulations and gain a competitive edge. At the time, most F1 teams used similar engines and gearboxes, so innovation in chassis and aerodynamics was crucial for differentiation.
The main idea was to introduce four small 10-inch front wheels, each with its own tire tucked behind the front wheel. It would technically reduce the drag force on the front wheels since they are hidden behind the wings, which would result in much stable and faster cars. The design was kept a secret even from Tyrrell’s driver until it was unveiled.
Was Tyrrell P34 Successful?
Despite its promising start, the P34’s success was short-lived. The most notable moment of the car came at the Swedish Grand Prix 1976 when Jody Scheckter and Patrick Depailler finished 1-2 on the podium, which marked the only time a six-wheeled car in F1 ever won a race. It also performed well in Monaco and other races, producing several podium finishes, which also helped Tyrrell finish third in the Constructors’ Championship that year.
Why Didn’t The Tyrrell P34 Succeed Long-Term?
The unique, small 10-inch tires were custom-made by Goodyear, who prioritized the development of tires used by most F1 teams, delaying the progress of these small tires, leading to limited long-term improvements.
The car’s four front wheels made it complex to set up and maintain. On bumpy tracks, the tires would often experience uneven grip, making the car unpredictable and difficult to drive.
While Patrick Depailler appreciated the car, Jody Scheckter called it “a piece of junk” despite his Swedish Grand Prix win and left the team at the end of 1976.
By 1977, the car was deemed uncompetitive due to a lack of development, and by 1978, Tyrrell abandoned the idea. Other teams also failed to develop a good six-wheeled car in F1. After that, FIA changed the regulations requiring a car to have only four wheels, marking the end of an era.
Hence, the Tyrrell P34 was an iconic innovation that challenged the regulations of F1. Nonetheless, it remains an icon in motorsport innovation and will forever be remembered for its legacy.
