In the end, the report on this phase was finished in July 1984 and then published in January 1985. The timetable for the project was for Phase I to be concluded by the end of 1984. General Dynamics EVTB (also known as the Advanced Hybrid Electric Drive vehicle). It also had possession of a 8 x 8 wheeled, 15-ton (13.6 tonne) Electric Vehicle Test Bed (EVTB) it had paid for itself in order to test and validate electric drive. General Dynamics had actually been looking into the potential of electric drive systems as early as 1981, producing electric-drive concept vehicles for various other vehicle projects. Phase III: A parametric study and evaluation with selection of 3 recommended concepts for further consideration
Phase II: Generation of concept vehicles with electric drive Phase I: A survey of existing technology (document JU-84-04057-002) Despite the billions of dollars spent, to date, the US military has yet to capitalize on the potential of electric-drive vehicles. To this day, in 2020, the M1 Abrams remains in service with a conventional power plant along with numerous other armored vehicles in the US inventory. However, like so many other studies, this work faded away and the design work was abandoned. What it actually generated was the realization that electric-drive fighting vehicles were not only possible but had some valuable features worth exploring, especially with regards to a series of heavy IFV platforms. The goal was roughly that of evaluating the ‘new’ (electric drive for vehicles predates armored vehicle) technology available across a variety of platforms for what it may offer for further development. This was contract number DAAE07-84-C-RO16 divided into 2 phases – a third phase was added later under contract modification P00006. The US Army’s Tank Automotive Command (TACOM) issued a contract to General Dynamics Land Systems for this project – to evaluate existing electric drive technologies to use in future vehicles. As part of the evaluation of trends in future vehicles, a commission looked into the potential for electric drive systems for a 40-ton (36.3 tonne) (tank) and 19.5-ton (17.7 tonne) (APC/IFV) platform. In 1984, the US military was considering the problems connected with a new range of vehicles, such as the new M1 Abrams main battle tank and M2 Bradley Infantry Fighting Vehicle (IFV).
