Low-profile, laser-applied powder-metal intake valve seats enhance the intake port efficiency and allow maximum coolant flow close to the spark plug. The exhaust valves’ shape has also been optimized to enhance cooling performance. This also contributes to cylinder head reliability and operating efficiency.

Because EVs run on electricity, the vehicle emits no exhaust from a tailpipe and does not contain the typical liquid fuel components in ICEVs. Lithium-ion batteries produce harmful fluoride gas when on fire, burn for longer, and are more difficult to put out than fossil-fueled fires. Learn more about gas vs. electric car fires here.
