European car bosses gathering for the Frankfurt auto show are beginning to address the realities of mass vehicle electrification, and its consequences for jobs and profit, their minds focused by government pledges to outlaw the combustion engine.
As the latest such announcement by China added momentum to a push for zero-emissions motoring, Daimler, Volkswagen and PSA Group gave details about their electric programmes that could give policymakers some pause.
Planned electric Mercedes models will initially be just half as profitable as conventional alternatives, Daimler warned - forcing the group to find savings by outsourcing more component manufacturing, which may in turn threaten German jobs.
"In-house production is almost irrelevant to the consumer," Daimler boss Dieter Zetsche told reporters on the eve of the Frankfurt auto show, in the midst of a German election campaign in which automotive jobs have loomed large.
The company set a target of saving 4 billion euros ($4.8 billion) by 2025 to help fund the cost of its electric cars.
"Daimler is the first company to state explicitly how much electric vehicles are going to hurt margins," said Bernstein analyst Max Warburton. "It was brave to go first - but of course it won't be the last."
Volkswagen (VW), for its part, said it was seeking new global supplier contracts to source 50 billion euros ($60 billion) of electric car content including batteries, which are not yet manufactured competitively in Europe.
"A company like Volkswagen must lead, not follow," Chief Executive Matthias Mueller told reporters.
VW diesel emissions-cheating exposed by US regulators in 2015 triggered global public outrage, dozens more investigations into test-rigging by the wider industry and a push by some lawmakers to ban diesel and eventually all engines.
Tesla Inc shares jumped nearly 6.0 per cent on Monday after a Chinese minister said it was a question of when, not if, Beijing bans fossil-fuel cars, tightening the noose around the combustion engine.
France and Britain have promised its outright abolition by 2040.
But PSA, the maker of Peugeots and Citroens, said it was concerned about the risks if consumers were left behind in the rush, and a new generation of battery cars does not sell.
"If it doesn't gain acceptance in the market, then everybody - industry, employees and politicians - has a big problem," PSA Chief Executive Carlos Tavares said in a pre-show interview with German weekly Bild am Sonntag.
