STUTTGART — Volkswagen’s stable of a dozen brands will source all V-8 gasoline engines in the future from Porsche, meaning high-powered vehicles such as the Bentley Mulsanne and Audi’s revamped A8 flagship due next year will come equipped with a Porsche engine.
The engine is being produced at a new site near Porsche’s 911 sports car plant here.
“Porsche’s new engine plant will also contribute towards synergies within the Volkswagen Group,” Porsche CEO Oliver Blume said this month at the opening of the new factory.
The sports car maker invested nearly 80 million euros ($88.6 million) in the plant, where 400 workers are expected to build roughly 200 units of the fourth-generation engine every day.
The 4.0-liter, V-8 aluminum engine — which will feature displacement on demand for the first time in a Porsche — can deliver up to 542 hp at 6,000 rpm, but it offers 335 hp at half that engine speed. Twin turbochargers are located centrally between the two opposing banks of cylinders rather than the outside to give the engine more compact dimensions and improve performance and handling.
The powerplant will debut in the Panamera Turbo, which launches in November and can accelerate from 0 to 62 mph in 3.8 seconds.
Despite its power, the engine is up to 30 percent more fuel-efficient than its predecessor thanks to its two-stage sliding camshaft that can deactivate four cylinders in partial load.
Porsche also is planning electrification of its engines. The current V-8 engines are built with a modular structure that would more easily encompass hybrid powertrains.
In the future, the factory also will manufacture an electric drivetrain for the Mission E, Porsche’s first purpose-built electric sports car, due at the end of the decade.
