Aerodynamic Efficiency

Where Design Meets Performance

Achieving aerodynamic efficiency by improving vehicle lift and drag can fulfill the top consumer demands of better fuel efficiency and compelling style. But waiting for wind tunnel tests to understand vehicle aerodynamics can result in rework, launch delays, and sub-par solutions that add cost and weight.


A high-performing aerodynamic car design doesn’t wait for the windtunnel. Only digital simulation with SIMULIA PowerFLOW lets you improve key elements of aerodynamic design – like lift to drag ratio –early in the product’s lifecycle when changes are easier to make. Simulation eith PowerFLOW surpasses the accuracy, repeatability, and consistency of wind-tunnel testing by applying real-world conditions to 3D geometry – including realistic wind, traffic turbulence, soil and water spray, rotating tires, and changing temperatures. Improve fuel efficiency, reduce late-stage failures and rework, and eliminate additional parts cost and weight with a design-stage view into automotive aerodynamics. Achieve both performance and styling – only with PowerFLOW.
