Vehicle Description
Designed by AC Propulsion & Alan Cocconi
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]
utilized an air cooler B&S ICE -- and we understand that there are
several examples of this version in operation.
The LongRanger II (17kW) [c1994] utilized  a 250cc water cooled
ICE -- and we know of only one operating example ever produced..
The LongRanger III (20kW) as pictured below, utilized a 500cc water cooled
ICE -- and  there are three known examples; one on the yellow tzero
pictured below, a second on the red tzero pictured below, and the third is
he TMC commissioned  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.
