In 1911 Pivot joined Koechlin; the Pivot-Koechlin, or Pivot, resembled the Deperdussins and was built by Audineau; it was similar to the previous monoplanes but more streamlined, with a radial engine and smaller trapezoidal rudders. The thin fuselage was faired out around the engine and pilot with round metal sheets ending in a cylindrical cowl for the engine, a Gnome or Rossel-Peugeot. The undercarriage was simpler than that used on the Deperdussins, with castering wheels and diagonal skids attached under the nose. The earlier pylons had disappeared, replaced with 4 long struts to brace the wings, attached to the wings and the undercarriage. The wingtip ailerons were actuated by movement of the pilot's body.
   A 3-seater version was mentioned, with 2 seats side-by-side behind the pilot: this was probably the one referred to as the Type Militaire. The Pivot was often described as the fastest machine of its time: 1911.

   From 1911 to 1913 Koechlin built racing cars with underslung chassis, but they failed to achieve their expected performance.
