A new technique for self-pierce riveting shows promise for joining mixed-material assemblies for EVs.

U.S. automakers are wrestling with the challenge of reducing vehicle weight to meet the 2025 CAFE (Corporate Average Fuel Economy) mandate, which requires new cars and trucks to achieve 55 miles per gallon. Meeting that challenge will require the latest advances in materials and fastening methods.

The need to reduce vehicle weight has spawned myriad new technologies for assembling aluminum, high-strength steel and other materials. These new technologies include self-piercing rivets, flow-drilling screws and friction-stir spot welding.
