It wasn’t until ten years later in Boston, Massachusetts when the first improvements on the Panhard design were implemented. The Sturtevant brothers equipped their auto- mobile with a two-forward-speed gearbox with two automatic friction clutches. The stress of changing gear ratios and the lack of technological advances in metallurgy left their offering prone to failures, and the car was never put into production to the masses. It did, however, plant the idea collectively into the minds currently working on auto- mobile manufacturing at the time that with perfection of the flawed areas, these obsta- cles could be overcome. With this in mind, it became clear that the limitations of two forward speed gear ratios must give way to a transmission that would allow varying be- tween maximum to deliver the most availa- ble acceleration, to the minimum so that the engine would not overload under normal driving conditions. This would inevitably be known as the infinitely variable gear trans- mission.
