2017 Porsche Panamera Turbo - Video
2017 Porsche Panamera Turbo In Crayon Color
The big news is the all-new twin-turbo 4.0-liter V8 in the Panamera Turbo. It adopts a “hot vee” layout with the turbochargers in the engine’s valley. This setup allows for a short run from the exhaust manifold for minimal lag, which is further reduced by the twin-scroll turbos. With 18.8 psi of peak boost, the new V8 pumps out 550 horsepower and 567-pound feet. As we mentioned, that’s just 20 hp behind the outgoing Turbo S. And the Panamera Turbo is quick – good for 0 to 60 mph in 3.4 seconds with the Sport Chrono pack. Yes, launch control looks awesome.
This is also the first Porsche engine to adopt cylinder deactivation – in four-cylinder mode the engine can run up to 3,500 rpm with as much as 123 horsepower. To shut down four cylinders at a time, the camshaft on each bank slides to engage a dummy lobe on cylinders two, three, five, and eight. When running in V4 mode, the valves stay closed on the shut-down cylinders. Another nod to emissions and efficiency is a catalytic converter mounted close up near the vee, right behind the turbos. All that heat requires airflow, so there’s a dedicated duct from the radiator that routes fresh air over the turbos and catalytic converter.
