FRANKFURT (Reuters) - European car bosses 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 on Monday by China added momentum to a push for zero-emissions motoring, Daimler DAIGn.DE, Volkswagen VOWG_p.DE and PSA Group PEUP.PA gave details about their electric programs 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 U.S. 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.

TIGHTENING NOOSE

Tesla Inc TSLA.O shares jumped nearly 6 percent 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.

While Tesla has carved itself a successful premium niche, electric vehicles have yet to penetrate mass markets, with the heavily subsidized exception of Norway, and still account for less than 1 percent of global car sales.

Automakers have sought to adapt to the changing tide - and in some cases distance themselves from “dieselgate” - by announcing multibillion-euro investments in electric cars, underpinned by plans to sell millions within a decade.

A year into the scandal, VW unveiled plans to develop 30 new electric cars and sell 2-3 million annually by 2025. On Monday it upped the goal to 80 models and said it would need four times the capacity of Tesla’s “gigafactory” to supply their batteries.

JOBS FLIGHT

Since the battery is the single biggest-value item in an electric car, however, experts point out that mass adoption would shift business and jobs from European suppliers to China, which already dominates the automotive power-pack market.

According to consulting firm AlixPartners, electric drivetrains including batteries require 40 percent less manufacturing labor than mechanical ones. That would hit 112,000 jobs at European suppliers, even before any outsourcing.

A phase-out of combustion engines by 2030 could cost 600,000 jobs in Germany alone, the country’s Ifo economic institute has warned. Chancellor Angela Merkel, on course for re-election on Sept. 24, said she was “no friend of bans”, in a Berliner Zeitung interview published on Tuesday.

Speaking to a television audience of voters on Monday evening, Merkel said the industry would need support in its transformation. “The government still has to do more to set incentives,” she said, without giving details.

Bosch, the world’s biggest automotive supplier, on Tuesday lamented the “one dimensional nature” of the debate, saying electric vehicles were not the only way to reduce pollution.

The German company is exploring synthetic fuels, which would have the advantage of being able to use existing filling stations and engines, its CEO Volkmar Denner told a news conference, adding this could potentially save 2.8 gigatonnes of CO2 by 2050 - three times as much as Germany produced in 2016.

“This is a faster way of limiting global warming,” he said.

Independent analyst Richard Windsor warned that far from boosting the industry, a shift to electric cars - which are expected to last longer than combustion-engined equivalents and require less maintenance - could inflict long-term damage.

“Vehicle makers are queuing up to announce their commitment to electric vehicles but at the same time they may be cheering for their own demise,” he said.
