> The cable harness used today is one of the three heaviest subsystems in the vehicle (weighing up to 60 kg)3. Traditional Ethernet cables use four differential pairs for data transmission, adding weight and routing complexity, which is not optimal for automotive applications. To address this, new IEEE standards were developed to support Ethernet transmission over single twisted pair cables, which, coupled with the reduced cable harness lengths enabled by zonal architecture, can offer significant cable savings and weight reduction.
Because in cars that are at least 1000kg, a few grams definitely matter.
