Porsche is expanding its hybrid range by adding a powerful plug-in hybrid to the Panamera Sport Turismo model line. Like the Panamera Turbo S E-Hybrid sedan, the Panamera Turbo S E-Hybrid Sport Turismo offers a compelling demonstration of the performance advantages of hybrid technology.

The new Panamera Turbo S E-Hybrid Sport Turismo utilises a boost strategy derived from the 918 Spyder and combines a 136bhp electric motor with a 542bhp twin-turbo V8 engine. Total output of the combined systems is 680bhp and 922Nm of torque.

The Turbo S E-Hybrid Sport Turismo offers all of the innovations of the second generation Panamera. These include the digitalised Porsche Advanced Cockpit, groundbreaking assistance system options such as Porsche InnoDrive, including adaptive cruise control and optional rear-axle steering.

At the top of the vehicle, the roof extends into an adaptive spoiler. The angle of the roof spoiler is set in three stages depending on the driving situation and selected vehicle settings, and can generate an additional downforce on the rear axle. In normal driving, the aerodynamic guide element - a central system component of Porsche Active Aerodynamics - stays in its retracted position with an angle of minus seven degrees, which reduces drag and thus optimises fuel consumption.

Standard equipment on the Panamera Turbo S E-Hybrid Sport Turismo includes Porsche Ceramic Composite Brakes, Porsche Dynamic Chassis Control Sport - including Porsche Torque Vectoring Plus, Power Steering Plus and the Sport Chrono Package. 21-inch 911 Turbo Design wheels, auxiliary air-conditioning, adaptive aerodynamic elements and a three-chamber air suspension - including Porsche Active Suspension Management - are also standard.
