3. A Robust Safety System Leveraging Pyrofuse Technology
The final piece is protection. In a high-voltage race car operating at this level, safety has to be built into the system from the beginning. A pyrotechnic circuit breaker (pyrofuse) is a key part of our strategy. It helps isolate the high-voltage system when needed and is engineered to support safe operation in a true racing environment. It does this by physically breaking the high-voltage circuit with a small detonation. It also helps that pyrofuses are lighter and faster-acting than their melting-fuse counterparts. Our team collaborated with the NHRA to develop a cut loop system that allows for safety workers to activate the pyrofuse from outside the vehicle to ensure safety in all situations. It is not separate from performance. It is part of the total system. When you are running at this level, safety, control, and power all have to work together.
That, to me, is what makes Cobra Jet 2200 so compelling. The ET and speed are impressive. But to solve the challenge in the right order - create extraordinary power density, develop the driveline control to manage it, and build the protection needed to run it safely at the highest level - is a seriously complicated puzzle of engineering ingenuity. Especially because in a drag car, everything is compressed into a few seconds and 150 revolutions of the rear tire, which means every decision gets exposed very quickly.
That is one of the reasons racing has remained such a powerful proving ground for us at Ford for 125 years as America’s Race Team.
