The horsepower wars continue. For those that just couldn’t get by with a mere 500 ponies, Porsche is offering the even more powerful Panamera Turbo S, which bumps the number up to as much as 550.
Set to go on sale this spring, the newest update of the Porsche 4-door flagship will make its formal debut at the New York Auto Show, later this month.
The big news will require lifting the hood, though there are some notable tweaks to the exterior of the Panamera, starting with new 20-inch Turbo II wheels which sit a bit wider due to the S-model’s wider track. There’s also an adaptive four-way extending rear spoiler to improve aerodynamic performance.
The Panamera Turbo S powertrain starts with the same 4.8-liter V8 found in the current twin-turbo model. But the newer sedan adopts a modified engine controller and twin turbochargers with titanium–aluminum turbines. The lightweight metal, Porsche claims, can spin up more quickly to improve performance. Officially rated at 550 hp, a 10% increase, torque climbs 7% to 553 lb-ft – and can temporarily peak at 590 lb-ft in overboost mode.
