Car industry: What's the real cost of going electric?

Under pressure from trade tariffs, new CO2 rules and even Brexit, carmakers around the world are electrifying.

Back in 1888, the electric car was all the rage. But the discovery of large petroleum reserves worldwide and the combustion engine quickly killed it off.

So what is the future of the automotive industry? What will it take to go electric? And what will be the real cost of it?
