Lightweighted Wheels Featured on ’15 Audi A8

Lacks Wheel Trim Systems looks to court OEMs with a technology that saves fuel through reduced wheel weight. The eVOLVE function builds upon Lacks’ existing Chromtec lightweight chrome wheel that meets car designers’ styling demands. eVOLVE adds a high-performance aluminum “backbone” for safety and stiffness, but uses a lighter, aerodynamic metal that reduces wheel weight up to 4.5 lbs. (2.0 kg). The weight savings per wheel can improve fuel economy up to 1.1 mpg (2.14 L/100km), an executive with Grand Rapids, MI-based Lacks says. “Lighter wheels tend to improve the ride and handling,” adds James Ardern, director-business development. Lacks announces at this week’s Frankfurt auto show that the function is featured on the ’15 Audi A8. The supplier is in talks with other OEMs to spread the technology.
