The first PA used an 847 cc (51.7 cu in) engine similar to the J-Type’s, now with a 3-bearing crankshaft, improved camshaft, and twin OM-model SU carburettors. It produced 36 bhp (27 kW) at 5,500 rpm, allowing a top speed of approximately 74 mph (119 km/h), and a 0–50 mph (80 km/h) time of 20 seconds. In 1935, a two-seater roadster cost £222. 1,973 PAs were made, 27 of which were eventually converted to PBs.
