In 1993, Ford was granted a five year collaborative contract with the US Department of Energy for the research and development of hybrid electric propulsion systems. Now, Ford's DOE hybrid program is a 5 1/2-year effort to analyze component tradeoffs for potential hybrid products, initiate design and development of fundamental enabling technologies, identify configurations and components for concept vehicle build, and build one or more hybrid test vehicles. Ford's approach to this program is best described as a 'clean sheet' investigation into ways of synergistically combining internal combustion engine technology and electric drive technology to provide a vehicle that has improved fuel efficiency and reduced emissions while maintaining the performance and utility that the customers enjoy today. As a result of extensive computer simulation and modelling work, Ford has identified two parallel hybrid propulsion system configurations that promise to meet the conflicting goals of high vehicle performance, low fuel consumption and tailpipe emissions, and low cost. These are the Post-Transmission Hybrid (PTH) where the electric traction motor is directly coupled to the wheels after the main geared transmission of the powertrain, and the Low Storage Requirement (LSR) hybrid where a small electric motor and battery are deployed. Installed in the light weight vehicle platform (P2000) and a newly developed, state-of-the-art compression ignition direct injection (CIDI) diesel engine (DIATA), the LSR vehicle will achieve about 68 mpg (3.5 l / 100 km) and the PTH 69 mpg (3.4 l / 100 km) while both are meeting at least Federal Clean Air Act default Tier II Emission standards. This standard was chosen since it was most likely to be in effect by the end of this program.
