The two-seat Allard Palm Beach was, as its name suggests, intended to appeal to the American market, and high-powered versions were capable of an impressive 120 mph top speed. The Palm Beach was built from 1952 to 1958.

The Palm Beach’s full-width aluminium coachwork had a rather different appearance to Allard’s previous models like the J2, but underneath was a similar tubular chassis. It was essentially a lighter version of the frame from the P2/K3 models. Suspension was by swing axles with coil springs up front and a live axle with coil springs at the rear. Brakes were drums. Buyers had the choice of two Ford engines. While most Allards are known for having the brute force of an American V-8, the Palm Beach had either 1.5-liter four- or 2.3-liter six-cylinder power. Wire wheels and a heater were on the options list.

At the Earls Court Motor Show in 1956, the company launched the Allard Palm Beach Mk II with a more attractive body and torsion bar front suspension. Different engines, including the engine from the Ford Zephyr and the Jaguar 3.4-liter XK, were also used. Production ended in 1958 after only about 80 Palm Beaches were built. Most of them were Mk I models.
