In 1920 the French automobile and aircraft pioneer Gabriel Voisin experimented with systems that modulated the hydraulic braking pressure on his aircraft brakes to reduce the risk of tire slippage, as threshold braking on aircraft is nearly impossible. These systems used a flywheel and valve attached to a hydraulic line that feeds the brake ...
The company is known for popularizing the straight-eight engine and four-wheel hydraulic brakes. A Duesenberg car was the first American car to win a Grand Prix race, winning the 1921 French Grand Prix.
