Scaling Cleaner Freight Movement

Aerodynamic Mirrors & Cameras

OEMs’ flagship aerodynamic models have optimized the cab mirror systems. Aerodynamic mirrors come as an integrated set with an aerodynamic cover that lowers drag.

With well-designed mirrors, aerodynamic drag can be reduced by 2% to 3%. Considerable OEM and supplier tradeoff studies and analysis have optimized production mirror head shapes and mounting systems.

For many years, federal regulations required two rear-vision mirrors, one on each side of the truck. In 2018, Stoneridge asked for and received an exemption from FMCSA to allow trucks to operate with its MirrorEye, a camera monitor system that replaces mirrors on trucks.
