The nervous system of the car is made of wire.
Cut open a modern car and you would find kilometres of wire. The single thickest component is not the drive shaft — it is the wiring harness.
- The wiring harness is the thickest component in the car: without wire, no indicators, no navigation, no adaptive cruise control.
- Safety-critical niches such as airbag mechanics rely on knitted wire mesh — small in volume, uncompromising in requirement.
- E-mobility has shrunk the exhaust-strand business — we say so openly, because the same adaptability now carries hydrogen and medical applications.
Cut open a modern car and you would find kilometres of wire. The single thickest component is not the drive shaft — it is the wiring harness: everything connected, everything wired, like a nervous system. Without it, no indicators, no navigation, no driver-assistance system.
Where wire is found in the vehicle.
Wiring harness & on-board network
Signal and power lines, shielding, plug contacts — the electrification of the vehicle is a wire story, and it grows with every assistance system.
Safety technology
Airbag mechanics rely on knitted wire mesh — a small, stable niche segment where reliability is non-negotiable.
Sensors & connection technology
Spring elements, clips and contact parts start out as precision-drawn wire with defined strength and surface.
Spring applications
From valve trains to the smallest actuators — spring wire with exact straightness quality.
The honest story: what e-mobility has changed.
For years, our group ran knitted wire mesh for combustion-engine exhaust strands — once two machines at full capacity. With e-mobility, that business has shrunk to sporadic small quantities. We tell this not because it is comfortable, but because it is true — and because it shows what this industry can do: the same capabilities now carry electrodes for hydrogen electrolysis and fine wire for medical technology. Applications disappear. Wire remains — in new form.
Why BenderWire.
Automotive demands reproducible quality at series scale: documented batches, alloy verification before shipment, material advice during design. And a supply chain that delivers even in turbulent markets — backed by roughly 2,500 t of wire stock and free sourcing.
Frequently asked questions.
Where is wire found in a car?
Above all in the wiring harness (signal/power/shielding), plus airbag mechanics, sensors, clips, springs — and in every screw.
What does e-mobility mean for wire applications?
Exhaust-strand applications shrink, while the on-board network, sensors and new fields such as hydrogen grow — the wire migrates with the technology.
Does BenderWire deliver automotive series quality?
Yes — with documented batches, mix-up prevention checks, and design worked out together with the customer.
