Lightweighting for NEVs: Safety Cannot Be Compromised — How This Bumper Beam Achieves 9% Weight Reduction While Withstanding 37kN Impact Load
Jul 30, 2026
Currently, as new energy vehicles universally pursue extended driving range, the accompanying increase in battery capacity has significantly added to overall vehicle weight. With curb weights frequently exceeding two tons, this not only leads to higher energy consumption but also impairs handling dynamics and places greater loads on tire and suspension systems. Under complex road conditions, it may even amplify risks such as vehicle instability or rollover tendencies.Achieving vehicle weight reduction while guaranteeing body structural strength and crash safety has become an unavoidable challenge in the R&D of new energy vehicles, as well as a key contributor to product competitiveness. Today, we will take a crash beam as an example to illustrate how new energy vehicles can reduce weig...
