In a strategic shift, Porsche said an upcoming line of sport utility vehicles, originally planned as fully electric, will now launch exclusively with combustion engines and plug-in hybrid options.

The agency said it suspects the cause was poor maintenance and inadequate ventilation in the inverter battery area, which caused overheating and combustion.

But even if that's true, next year is not just about internal combustion engine performance.

In that situation, the internal combustion engine is effectively being used as an energy generator for the battery.

The greatest invention of the Industrial Age isn’t the iPhone or lithium-ion batteries or even the internal combustion engine — it’s public health.
