The Porsche Panamera Turbo Sport Turismo is a standalone model that comes in a single configuration. A 4.0-liter twin-turbo V8 with 550 hp and 567 lb-ft of torque is sent through an eight-speed dual-clutch automatic gearbox, with all four wheels receiving power. This allows the Turbo Sport Turismo to accelerate from 0-60 in the mid-three-second bracket, topping out at 188 mph. In addition to eviscerating performance in a straight line, a standard adaptive air suspension setup keeps occupants comfortable, as do features like standard heated seats and available massage and ventilation functions. Adaptive LED headlights are also included and a Bose sound system keeps occupants entertained when you’re not carving up corners or breaking land speed records. Options include a 21-speaker Burmester sound system, a head-up display, a night vision camera, adaptive cruise control, and quad-zone automatic climate control.
