Vehicle electrification - machining content

Technology & Product Transition · Electrification

What it is

Electrification removes the engine block, cylinder head, crankshaft, camshaft, gearbox and exhaust - the most machining-intensive components in a vehicle - and replaces them with an electric motor, reducer and battery housing

The replacements need fewer machined surfaces but tighter tolerances and more aluminium

Impact on industries

  • Machining content per vehicle falls sharply, and the components lost are precisely the high-precision, high-value work that supported tooling demand
  • Aluminium housings, motor components and battery enclosures need different tooling and higher-precision finishing, so content shifts rather than disappearing entirely
  • India's ICE parc and production will persist for years, so the transition is gradual and gives suppliers time to reposition
  • Requalification is not automatic - a supplier machining ICE powertrain must win the EV platform separately, opening the door to new entrants
