Gas Turbine Vehicle.

Shown at the 1985 Tokyo Motor Show.

Used the Gas Turbine II engine. A regenerator took waste heat and transferred it to the incoming air, increasing efficiency. A one stage turbine was used to drive the compressor while a second turbine was connected to the driveshaft. The second stage also took the place of the fluid flywheel (torque convertor).

The main advantages of a gas turbine engine are:

  • fewer moving parts,
  • efficient rotational movements instead of inefficient reciprocating movements,
  • more tolerant of different fuel types and grades,
  • no need for water cooling, water pumps and radiators.

The main disadvantages are:

  • high internal temperatures,
  • high precision required during manufacturing (costly).

Earlier versions of the Gas Turbine engine were shown at the 1975 (in the Toyota Century) and 1977 (freestanding) Tokyo Motor Shows.
