Electric Vehicle Aerodynamic Design
See the difference design makes
Electrification and autonomy are changing vehicle design as we know it. Consumers and regulators are demanding green vehicles with dependable battery life and increased range, which introduces aggressive new targets for automotive aerodynamics. But design changes that reduce aerodynamic drag for electric vehicles can actually increase the soiling effects of on-road dirt, dust, and water – obscuring the cameras and sensors that are vital to autonomous systems.
As electrification and autonomy converge in tomorrow’s vehicles, design and engineering teams need to keep up. Only aerodynamic simulation with Exa’s PowerFLOW suite offers the early, accurate prediction of electric vehicle performance under real-world conditions when geometry is still in-work and changes are easier to make. Product development organizations can identify the right design changes sooner, before costly physical prototyping, to improve vehicle aerodynamics and autonomy together.
