In 1967, Piper introduced the PA-28-180 Arrow. This aircraft featured a constant-speed propeller and retractable landing gear and was powered by a 180 horsepower (134 kW) Lycoming IO-360-B1E engine. The engine was upgraded to a Lycoming IO-360-C1C of 200 horsepower (149 kW) in 1971 and the designation was changed to PA-28R-200. At the time the Arrow was introduced, Piper removed the Cherokee 150 and Cherokee 160 from production.
