 To reduce the risks involved with engine failure, the W.8e was developed with one 360 hp (270 kW) Rolls-Royce Eagle IX in the nose and two 240 hp (180 kW) Siddeley Pumas in the normal position.The first W.8e was sold to Sabena, which had ten more built in Belgium by SABCA.One three-engine W.8f was built with cabin heating (derived from air circulated around the hot engine exhausts).
