As expected, PSA-owned Opel will develop the next-generation of high-efficiency petrol engines for all Groupe PSA brands (Vauxhall, Opel, Peugeot, Citroën, and DS Automobiles) at its engineering centre in Rüsselsheim, Germany.

Opel says the next generation of four-cylinder engines will be optimised for operation in combination with electric motors and will be used in the drivetrain of hybrid systems. Market-introduction will begin in 2022.

The new generation of engines is designated for use in all Groupe PSA brands in China, Europe and North America, meeting the future emission standards of these markets, Opel says. The power units will feature technologies such as direct-injection, turbocharging and variable valve control.

"Rüsselsheim already had global responsibility for engine development when we were still part of GM. With the development of the new generation of four-cylinder petrol engines, we can exploit one of our key competencies. The economic direct-injection, in combination with hybrid technology, will consolidate the strong position of Groupe PSA in lowering CO2 emissions," said Opel's Managing Director Engineering, Christian Müller.

The Rüsselsheim engineers are now developing the new engine generation on the basis of the current Groupe PSA four-cylinder all-aluminium PureTech 1.6L units.

The upcoming four-cylinder units form the second petrol engine family of Groupe PSA from 2022 alongside the three-cylinder PureTech turbo engine.
