Are there any aircraft with powered landing gear?
WheelTug makes an addon motor for a nose wheel. This is a demo of the unit being developed for a B737. They intend to lease it to airlines. It works well under most circumstances, but has difficulty on icy aprons and the aircraft would need a pushback so it could taxi using its engines. The terms of the lease would financially compensate. They have "reservations" for 1100 units from two dozen airlines.

There are a number of financial considerations, such as cost to carry the weight of the unit. Here is a presentation of their business case. They claim direct cost savings similar in value to installation of winglets, and time savings value twice as great as replacing a current generation 737/320 with a Max/Neo.

Safran also had a joint venture to develop a similar unit for aircraft maingear, but that is no longer being pursued. I don't know of any OEM that offers this kind of capability on commercial aircraft.
