Both the TwinRanger and another planned version, the Bell 440, were attempts to market a twin-engine development of the Model 206L LongRanger.

The TwinRanger name dates back to the mid-1980s when Bell first considered developing a twin-engine version of the LongRanger.

[1] Bell also planned the single-engine 400A, and the 440 twin with a larger fuselage made possible by a high degree of composites.

Bell suspended development of the 400/440 family in the late 1980s as it felt unable to achieve a profitable production rate of 120 units a year.
