Porsche says that the Panamera is 76 inches in width, making it an especially wide sedan. A Mercedes-Benz S-Class, by comparison, is less than 74 inches wide. The Panamera measures 55.8 inches in height and 195.7 inches in length. This makes for a roomy interior, especially for just four passengers. The cabin is complete with 18-way adjustable front seats, and 8-way adjustable rear seats.
The entry-level powerplant is Volkswagen's 3.6-liter six-cylinder engine with 300 horsepower. The 'S' model will deliver 400 horsepower from a 4.8-liter V8, and the Turbo variant will offer an estimated 500 horses.
Porsche also added the Panamera 4, which adds all-wheel drive to the base 300 horsepower model, and the Panamera 4S, which adds all-wheel drive to the 400 horsepower V8 model.
The Panamera S will start at $89,800, while the all-wheel-drive 4S will cost $94,700. The Turbo will ring in at $132,600, which is slightly more than a Cayenne Turbo. U.S. sales are to begin in October.
The rear-wheel drive Panamera S can sprint from zero to 60 mph in 5.2 seconds on its way to a top speed of 175 mph. The Panamera 4S can hit 60 in 4.8 seconds and achieves the same top speed. The all-wheel drive Panamera Turbo sets a zero to 60 time of 4 seconds flat and a top track speed of 188 mph.
All models are equipped with Porsche's new PDK dual-clutch gearbox. Porsche is also planning a hybrid variant of the Panamera, though the automaker failed to disclose any further details.
The turbocharged version comes standard with all-wheel-drive. Rear-wheel-drive will be standard otherwise with four-wheel propulsion a line-wide option.
