Breaking: 542 HP Porsche Panamera Turbo S

Porsche has just released details and pictures of its fastest and most powerful variant yet of their four-door Panamera. The Panamera Turbo S is powered by a twin-turbo 4.8-liter V8 that's been increased to 542 hp, up from the Turbo's 493 hp. Looking at some numbers, this makes it faster than the Mercedes S63 AMG (518 hp) and the BMW 760Li (537 hp). With a top speed of 191 mph, it can go 3 mph faster than the standard Turbo.

Amazingly, its 0 to 62 mph time is just 3.8 seconds, which makes the Turbo S even faster than a 911 GT3 RS (which does it in 4 seconds flat). So how did they accomplish this? Porsche states that their engineers fitted titanium-aluminum turbine wheels to the turbochargers and then revised the engine control management. Torque is also up over the standard Turbo, now from 510 lb-ft to 553 lb-ft when driven in Sport and Sport Plus modes, and up to 590 lb-ft with the overboost function.

And leave it to Porsche to find a way to accomplish all of this without sacrificing fuel economy, which remains at 24.6 mpg combined. This was possible because of the car's lighter weight and lower inertia of the turbine and compressor wheel in the turbochargers. The Turbo S comes standard with the Porsche Dynamic Chassis Control boost and the Porsche Torque Vectoring Plus, which works with an electronically controlled limited-slip differential that applies a variable torque split to the rear wheels for better traction and agility.

Styling changes include new 20-inch Turbo II wheels, a sports exhaust and a two-tone leather interior. Set to go on sale this June, pricing starts at €167,076 or $173,200 USD.
