 When Continental Motors became part of Teledyne in 1971, engineers had already been at work for several years on the first all-new General Aviation engine to be developed in decades, the Tiara.

The powerplant had relatively small displacement but a good horsepower-to-cubic-inches ratio because it developed its power at high rpms.

The engine’s unique feature was Hydra-Torque drive, a patented system that could be hydraulically locked so the camshaft drove the propeller directly, providing a 0.5 speed reduction. Its singular advantage, according to the engine maker, was that the arrangement eliminated torsional vibration resonance at speeds from idle all the way to the Tiara’s redline at 4,500 rpm.
