Because of the car's lightness, due to its simple body, and being equipped with a 3.6 litre flathead Ford V8 engine, the vehicle was capable of reaching 149.67 km/h (93 mph). Some cars were built using Mercury V8 engines as well.
It is believed that the Allard K1 was never offered for sale outside of the United Kingdom, but records indicate that a few were shipped to different countries around the world, including Argentina, Australia, Belgium, Brazil, and the United States.
