The Panamera Turbo is the upper-level version of Porsche’s BMW 7-series fighting Panamera large sedan. While the styling of the vehicle has been a matter of controversy since day one, its ability to carry four passengers in supreme comfort while providing a level of performance belying its size is indisputable.
The Panamera Turbo is powered by a twin-turbocharged 4.8-liter V8 mated to a slick-shifting double-clutch gearbox Porsche affectionately dubs the Doppelkupplungsgetriebe (or PDK for non-Germans). With 500 horsepower and an earth-shattering 516 lb-ft. of torque on tap (which jumps to an outrageous 568 lb-ft. in overboost mode with the optional SportChrono package), zero to sixty comes in the four seconds flat while the top speed is 188 mph.
The car features an active all-wheel drive system dubbed Porsche Traction Management (PTM) that provides enhanced traction for safer all-weather driving in addition to increased performance. The system is a hang-on drive unit, integrated in the housing of the gearbox. An electronically controlled multiple-plate clutch integrated in the gearbox distributes drive forces between the rear axle permanently under drive power and the front axle in a fully variable process without a pre-determined power split.
With sensors permanently monitoring driving conditions, PTM can respond instantaneously to different driving requirements and situations. Sensors constantly monitor the speed of all four wheels, the car’s straight-ahead and lateral acceleration, as well as the steering angle. As soon as the rear wheels start to spin when accelerating, for example, the multiple-plate clutch intervenes more sharply to feed more power to the front wheels. In curves, the flow of power to the front wheels is carefully monitored to ensure optimum lateral stability at all times.
Whenever the car's brake control systems intervene, PTM disconnects the front axle completely, allowing stability control to intervene individually on the appropriate wheels.
For those times when forward progress becomes entirely too rapid, the Panamera Turbo features composite brake discs on the front axle measuring 15.35 inches in diameter, while at the rear four-piston aluminum monobloc fixed-calipers with brake discs measuring 13.78 inches across help slow things down. The brake discs are inner-vented for efficient heat dissipation and come with grooves in the surface to improve frictional behavior.
The Panamera Turbo utilizes Porsche Dynamic Chassis Control (PDCC), a damper-control system that works to almost completely offset body roll in curves, helping to ensure agility and an optimum balance.
Inside, the Panamera Turbo has an elegant leather-trimmed interior with a high center console that is easy to decipher despite the plethora of buttons. The instrument panel is comprised of five circular gauges with the tachometer in the middle, much like in the 911, and the ignition lock is placed to the left of the steering wheel. The standard navigation system is controlled via a seven-inch touchscreen on the center console.
Many features that are optional on lesser Panameras are fitted as standard to the Panamera Turbo, including 14-way power seats with memory, heated seats front and rear, a heated steering wheel and a ParkAssist front and rear proximity warning system.
Also standard is a BOSE Surround Sound system developed specifically for Panamera. A total of 14 loudspeakers, a 200-watt active subwoofer as well as nine amplifier channels ensure a truly impressive aural experience. Overall output is 585 watts.
The Panamera Turbo comes equipped with 8 airbags, including dual front, side-impact and curtain airbags. Knee airbags are integrated into the lower part of the instrument panel and hold back the lower body of the driver and front passenger in a head-on collision.
As with all Porsche models, the Panamera Turbo offers a wide range of options for those willing to pay extra.
Adaptive sport seats with 18-way electric adjustment are available as an option for the front occupants and offer firmer upholstery and even more lateral support. Comfort seats at the rear with a wide range of electrical adjustment are available as an option, as well.
Those in warm climates might consider the four-zone climate control system and ventilated seats.
For more precise handling there is the Porsche Torque Vectoring Plus (PTV Plus) system, which is designed to help improve both driving dynamics and the stability of the car. The system serves to variably spread out drive forces on the rear wheels and incorporates an electronically controlled rear axle differential. As a function of the steering angle and steering speed, the position of the gas pedal, the yaw rate and the speed of the car, PTV Plus applies the brakes slightly on the inner rear wheel as soon as the driver turns the steering wheel, thus passing on higher drive forces to the outer rear wheel in a curve and generating an additional turning movement in the desired direction.
Servotronic speed-sensitive power steering is also an option. At high speeds, Servotronic keeps the steering firm and taut, ensuring precise steering maneuvers. At low speeds, Servotronic increases the power assistance, making maneuvering in the parking lot smooth and easy.
For those who want arrestingly power brakes, there are the Porsche Ceramic Composite Brakes (PCCB) featuring brake calipers finished in yellow. These race-inspired high performance brake discs measure 15.35 inches (390 millimeters) in diameter at the front and 13.78 inches at the rear.
The Sport Chrono Package Plus offers a dual analog/digital stopwatch mounted on the dashboard. More importantly, the package nets launch control, a performance transmission mode and a “overboost” mode that raises torque to 568 lb-ft. for short accelerative bursts.
True audiophiles will opt for the Burmester sound system. Also developed specifically for the Panamera, the system has more than 372 square inches of speaker surface area that offers a dynamic sound experience comparable to a live concert. The 16 loudspeakers controlled by 16 separate amplifier channels create an overall output of more than 1,000 watts, rounded off by an active subwoofer with a 300-watt class-D amplifier.
Finally, two option packages are available that bundle together some of the previously mentioned stand alone options.
The premium plus package includes a rearview camera, a power rear sunscreen, power rear side sunscreens, 8-way rear power seats, four-zone climate control and adaptive cruise control.
The sport package features 18-way adaptive sports seats, a sport exhaust system, and PTV Plus.
