FASTSim: Future Automotive Systems Technology Simulator

The Future Automotive Systems Technology Simulator (FASTSim™) provides a simple way to compare powertrains and estimate the impact of technology improvements on light-, medium-, and heavy-duty vehicle efficiency, performance, cost, and battery life.

This extremely fast simulation tool features a streamlined user interface and can rapidly perform a variety of tasks using basic computing resources:

• <0.1 second to simulate second-by-second standard duty cycles
• <10 seconds to estimate vehicle efficiency, fuel economy, acceleration, battery life, and cost
• <5 minutes to perform powertrain comparisons of efficiency and cost.

FASTSim models a variety of vehicle powertrains and fuel converter types:

• Conventional vehicles — spark ignition, Atkinson, diesel, and hybrid diesel
• Electric-drive vehicles — hybrid, plug-in hybrid, and all-electric
• Hydrogen fuel cell vehicles.

The default model includes a variety of vehicles and duty cycles and an option for adding additional vehicles and custom cycles:

• Packaged with more than 20 vehicles
• User interface enables addition of more vehicles
• Includes standard U.S. drive cycles as well as European and Japanese cycles.
