Tucker's specifications for his revolutionary car called for a rear engine, a low-RPM 589 cubic inch engine with hydraulic valves instead of a camshaft, fuel injection, direct-drive torque converters on each rear wheel (instead of a transmission), disc brakes, the location of all instruments within the diameter and reach of the steering wheel, a padded dashboard, self-sealing tubeless tires, independent springless suspension, a chassis that protected occupants in a side impact, a roll bar within the roof, a laminated windshield designed to pop out during an accident, and a center "cyclops" headlight which would turn when steering at angles greater than 10 degrees in order to improve visibility around corners during night driving.
