Who will rule the Teslaverse?

A RECENT VIDEO of Elon Musk taking a spin in a new all-electric Volkswagen with Herbert Diess, the German carmaker’s boss, set tongues wagging. VW was forced to deny that a deal with Tesla was in the offing. A deeper bromance between Mr Musk’s firm and his main rival in the market for electric vehicles (EVs) looks unlikely. But the meeting highlights how the car industry is at last taking the impending EV revolution seriously.

Giant new businesses are gearing up to support the switch from petrol to electricity. Besides changing the way cars are propelled, this requires batteries, software to ensure these work in harmony with motors, and data harvested from cars that may one day allow them to drive themselves. Over 250 firms are manufacturing electric motors. Forty-seven battery factories are under construction. Anjan Kumar of Frost & Sullivan, a consultancy, expects total new EV-battery capacity to go from 88 gigawatt-hours in 2019, enough to power Texas for less than two hours if plugged into the grid, to 1,400 gigawatt-hours in 2025. Established carmakers are pondering how to loosen the grip of big tech on software.
