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.
FASTSim is fast. Simulating a second-by-second standard drive cycle takes under a tenth of a second, estimating a vehicle’s efficiency and related metrics takes less than ten seconds, and comparing powertrains on efficiency and cost completes in under five minutes.
It can represent a wide range of powertrains, including conventional vehicles (spark ignition, Atkinson, diesel, and hybrid diesel), electric-drive vehicles (hybrid, plug-in hybrid, and all-electric), and hydrogen fuel cell vehicles. FASTSim ships with more than 20 vehicles and a set of standard U.S., European, and Japanese drive cycles, and you can add your own vehicles and drive cycles.
