Manufacturer: Emrys Industries Nomenclature: EM-K4-P3301 Type: Electric Turbofan Class: Propulsion Designer: Emrys Industries R&D section.

The Electric Turbofan Jet Engines (ETJE) are designed to provide extra propulsion for high speed travel. They are powered by the car's generator. Air is drawn into the turbines via the ducts in the sides of the car and forced out through the nozzles in the rear of the car. There is no combustion so the ETJE does not have hot exhaust.

Note: The control system will not allow the ETJE to operate below 300 meters, or within a municipality’s traffic grid. Note: The ETJE will not operate in a vacuum as there are fail-safes to keep it from turning on.
