Sumitomo Riko eAxle Cover Adopted for Lexus RZ Electric Vehicle

Sumitomo Riko Company Limited announced on July 8 that its newly developed eAxle cover has been selected for use in the Toyota Motor Corporation Lexus RZ electric vehicle. The component features a newly developed high-rigidity urethane material engineered to combine excellent sound absorption with enhanced structural rigidity. This latest adoption highlights the company's efforts to improve electric vehicle component performance while supporting lightweight vehicle design and more efficient manufacturing processes.

New High-Rigidity Urethane Material Improves Performance

The newly developed eAxle cover is manufactured using a single-material high-rigidity urethane structure that delivers sound insulation performance comparable to conventional covers made from composite resin and urethane materials. By achieving both rigidity and acoustic performance with one material, the design simplifies overall construction without compromising its intended functionality for electric vehicle applications.

Benefits of the New eAxle Cover for the Lexus RZ

The updated cover also simplifies installation onto the e-axle, making assembly more efficient during vehicle production. Its lightweight design contributes to overall vehicle weight reduction while also helping lower carbon dioxide emissions generated during manufacturing. These combined advantages support improved production efficiency alongside environmental sustainability, making the component well suited for modern electric vehicle platforms such as the Lexus RZ.
