Only a few were built between 1928 and 1932, although samples fitted to a Westland Wapiti held the altitude record for diesel-powered aircraft at 27,453 ft (8,368 m) from 11 May 1934 until World War II.[1] The primary advantage of the Phoenix was better fuel efficiency at cruise, by up to 35%.

El Phoenix fue una versión experimental del motor Pegasus de la Bristol Aeroplane Company, adaptado para funcionar con el ciclo diésel. Se cosntruyeron sólo unos pocos ejemplares entre 1928 y 1932, aunque los ejemplares colocados en el Westland Wapiti tuvieron el récord de altura para aviones con motores diésel de 8.368 m, obtenido el 11 de mayo de 1934 hasta la Segunda Guerra Mundial.[1] La pricnipal ventaja del Phoenix era una mayor eficiencia del combustible en crucero, por arriba del 35%.
