Exa's Simulation Technology Critical to Achieving 75% Fuel Economy Improvements for Cummins, Perterbilt SuperTruck

Exa® Corporation (Nasdaq:EXA), a global innovator of fluids simulation solutions for product engineering, stated that Cummins Inc. and Peterbilt Motors Company, the first companies to announce their SuperTruck for the Department of Energy (DOE) SuperTruck Program, credited Exa's technology and engineering expertise as instrumental in the success of their recently announced vehicle. Exa worked with engineers from both Cummins and Peterbilt to perform aerodynamic and thermal simulations to achieve significant efficiency improvements throughout the tractor, trailer and engine. These simulations, done long before a physical prototype was ever created, helped this SuperTruck exceed the required 50% efficiency improvement, and deliver a 75% more efficient truck — ahead of schedule.
