Mack Trucks has introduced a groundbreaking windshield technology designed to enhance the durability, damage resistance, and total cost of ownership for heavy-duty trucks. The innovative ImpactShield windshield is now available on all-new Mack Granite models, marking a significant milestone in the company's commitment to improving vocational applications.
The new Mack Granite features a galvanized steel cab, 270-degree radar coverage, Electronic Park Brake with rollaway protection, and a redesigned interior developed with driver input. This comprehensive redesign aims to improve safety, comfort, and overall driving experience for vocational trucking operations.
Corning Fusion5 Glass, the cutting-edge technology behind ImpactShield, was specifically engineered for automotive exterior applications. Its unique properties enable it to resist impacts, environmental wear, and weathering, resulting in improved durability and reduced maintenance costs.

The ImpactShield windshield boasts impressive performance metrics, including two times better sharp impact resistance, two times better thermal shock resistance, five times better scratch resistance, and improved defrost performance compared to standard Class 8 windshields.
According to Mack Trucks, the bonded curved windshield design is intended to improve durability by reducing unplanned service events and replacement costs over the life of the vehicle. This innovative approach aims to minimize downtime and maximize uptime for vocational trucking operations.
The collaboration between Mack Trucks and Corning, maker of Gorilla Glass, has resulted in a game-changing technology that addresses breakage while providing economic benefits to customers. The partnership demonstrates the potential for industry partnerships to drive innovation and improvement in heavy-duty trucking.

Mack ImpactShield windshield will be standard on all-new Mack Granite models, scheduled to be available for order in the second half of 2026. Production is expected to begin in January 2027 at Mack's Lehigh Valley Operations facility in Macungie, Pennsylvania.
The technology will also be available as an upgrade option on Mack Aero windshields for select Mack models, further expanding its reach and benefits to vocational trucking operations.
As the industry continues to evolve, the adoption of ImpactShield technology is poised to play a significant role in reducing maintenance costs and improving uptime for vocational trucking operations. With its impressive performance metrics and comprehensive design, Mack ImpactShield windshield is set to revolutionize the heavy-duty trucking landscape.
