WheelTug is a fully integrated ground propulsion system for aircraft which puts a high torque electric motor into the hub of the nose wheel to allow for backwards movement without the use of pushback tugs, to allow for forward movement without using the aircraft's engines, and to allow for rotation of the aircraft at the gate. By rotating the aircraft at the gate using WheelTug, both the front and rear door of the aircraft can be used for faster boarding. The company refers to this aircraft rotation at the gate as the WheelTug Twist and the WheelTug Twirl.
The electric motor in the nosewheel drives the aircraft with power supplied by the onboard APU (Auxiliary Power Unit) rather than engine power, which reduces emissions, fuel usage, brake wear, and F.O.D..
WheelTug's Order Book is 785  aircraft systems and the company website lists the following airlines in the order book: El Al, Jet Airways, Israair, Alitalia, Onur Air, KLM, Corendon Airlines, Airberlin, Iceland Air, Malaysia Airlines, Volaris, Air Transat, Hainan Airlines.
Boeing Phantom Works and Chorus Motors tested the WheelTug Concept on an Air Canada 767 in June 2005 at the Evergreen Air Center at Pinal Air Park in Marana, Arizona. WheelTug Limited and Co-Operative Industries completed an Electrical Load Measurement (ELM) on a B737NG in January 2010 at Hartsfield-Jackson International Airport in Atlanta, GA to confirm sufficient power. Tests were conducted at Prague Airport in November 2010 in snowy and icy conditions. The first fully 'in-wheel' demonstration unit was tested at Prague Airport June 2012.
