The Sport Turismo's powertrain is the same as the four-door version, pairing a twin-turbo V8 with an electric motor to produce 680 horsepower and 626 pound-feet of torque. It'll do the 0-60 sprint in just 3.2 seconds on its way to a top speed of 192 miles per hour. Ceramic composite brakes are standard, along with Porsche Dynamic Chassis Control Sport with torque vectoring, three-chamber air suspension with Porsche Active Suspension Management and 21-inch 911 Turbo Design wheels. The Sport Chrono Package is also standard.
The Sport Turismo has a raised roofline, providing more headroom and rear storage space. At the rear of the roof, it features a three-stage adaptive spoiler that can produce up to 110 pounds of additional downforce (or optimize aerodynamics for efficiency, depending on the driving situation). Inside the car, it has three rear seats that can fold down for a maximum of 45.7 cubic feet of storage space, or optionally a posh pair of reclining rear buckets. The car is also equipped with Porsche's digital cockpit, Porsche InnoDrive driver assistance technology. Rear-axle steering is an optional feature.
Porsche is now taking orders for the 2018 Panamera Turbo S E-Hybrid Sport Turismo, which is priced at a starting MSRP of $189,450 including destination. Deliveries begin in the spring of 2018.
