The redesigned Porsche Panamera's available twin-turbo 4.0-liter V-8 will also power certain Audi and Bentley models, Automotive News reports. The all-new engine will make its debut in the Panamera Turbo.
Porsche is supplying the V-8 engines from its new plant in Stuttgart, Germany. "Porsche's new engine plant will also contribute towards synergies within the Volkswagen Group," Porsche CEO Oliver Blume said at the opening of the new factory earlier this month.
The all-new twin-turbo 4.0-liter V-8 will produce up to 542 hp at 6,000 rpm, but is said to make 335 hp by just 3,000 rpm. A "Hot V" design, where the turbochargers sit in between the cylinder heads, makes the engine more compact overall. The compact design along with its lightweight all-aluminum construction is said to improve performance and handling. Porsche claims the new Panamera Turbo will reach 62 mph in 3.8 seconds.
In addition to being more powerful than the outgoing Porsche V-8, the new engine is said to be 30 percent more fuel efficient thanks to the automaker's first use of cylinder deactivation. Four cylinders can be deactivated during partial load thanks to a new two-stage sliding camshaft.
The engine is also said to be built around a modular design enabling it for use in a hybrid powertrain setup. Porsche has invested nearly $88.6 million in the new engine plant, which is located not too far from the 911 factory. With its 400-employee workforce, the plant can crank out around 200 engines a day. The factory will eventually build the drivetrain for the fully-electric Mission EV sports car.
