Bill of Materials (BOM) & Margins
- ICE Vehicles: Mature and highly optimized supply chains. The engine, transmission, and exhaust systems are major cost centers. Gross margins are well-understood and can be strong, especially on large trucks and SUVs which are highly profitable for US-based OEMs.
- EVs: The battery pack is the single largest cost component, often accounting for 25-40% of the total vehicle cost. This significantly pressures gross margins. Achieving margin parity with ICE vehicles is a primary goal for all OEMs and is heavily dependent on falling battery prices (e.g., from cheaper LFP chemistries), manufacturing scale, and software-enabled features.
Capital Expenditures (Capex)
- ICE-related Capex: Primarily maintenance and minor upgrades for existing plants. Investment in all-new ICE platforms is rapidly declining ("peak ICE").
- EV-related Capex: Massive investment required for all-new dedicated EV platforms ("skateboard" architectures), battery pack assembly plants (gigafactories), and retooling existing assembly plants to handle EV production. This creates a huge capital burden during the transition.
