The iconic six-wheel Elf-Tyrrell P34 unveiled: Autoweek archives

The Elf-Tyrrell project P34 six-wheeler remains one of the most radical designs ever presented for a Formula One car. This selection from the Autoweek archives comes from Sept. 27, 1975, when the P34 was revealed by Derek Gardner, chief designer for the Tyrrell Racing Organization.

The unconventional design offered improved aerodynamics through increased downforce and a larger tire contact patch through the use of its four 10-inch front wheels.

Power was delivered through a Ford-Cosworth naturally aspirated V8 that churned out 485 hp on its way to a redline north of 10,000 rpm.

The P34 premiered at the Spanish Grand Prix in 1976. Over the next 30 races the car took first once and had a total of 14 podium finishes in its two-year run.

Today, the Elf-Tyrell P34 still draws a crowd, appearing at various vintage-racing shows and competitions throughout the world.
