Vehicle Description

LongRanger III (v3)

RXT-G stands for Range Extending Trailer - Generator and has also been referred to
as the "LongRanger," "Range Extender," or "GenSet."   This unit converts a BEV
(Battery Electric Vehicle) to a series hybrid for long distance & cross country travel.

The history of the Long Ranger includes three prototype versions built between 1992
& 2001 for various applications.  The LongRanger I (9kW) [c1992] utalized an air
cooler B&S ICE -- we understand that there are several examples in operation.  The
LongRanger II (17kW) [c1994] utalized  a 250cc water cooled ICE -- and we know of
only one operating example, although there very well may be more.  The
LongRanger III (20kW) utalized a 500cc water cooled ICE -- and  there are three
known examples; one on the yellow tzero pictured below, a second on the tzero
pictured bleow in red, the last is the TMC comissioned  prototype for the NiMH
Rav4-EV pictured below in white (and is the example held in our collection).

Owning to the BEVs "electric first" design, series hybrids are capable of greater fuel
economy when compared to standard OEM parallel hybrid drives; which, by
definition, rely on "ICE first" with an electric boost to ICE operations.  We believe BEV
series hybrids are the future and the next logical step to much greater fuel economy.
