2021 Porsche Panamera Excellent Sport Sedan

Porsche's asphalt-storming second-generation Panamera benefits from a few powertrain updates and subtle styling changes this year, and Stuttgart sent us three versions for Car of the Year evaluation: a base model, now with a 2.9-liter twin-turbo V-6 (replacing the previous 3.0) making 325 horsepower and 331 lb-ft of torque; a GTS with its 4.0-liter twin-turbo V-8 fortified by 20 ponies to make 473 hp along with its carryover 457 lb-ft of torque; and a Panamera 4S E-Hybrid Sport Turismo wagon. The 4S E-Hybrid is a new trim level powered by a 2.9-liter twin-turbo V-6 plus an electric motor, good for 552 horses and 553 lb-ft. Plug-in hybrid versions now benefit from an 18.0-kWh battery pack versus the 14.0-kWh pack of 2020 models, increasing their electric-only driving range from an EPA-rated 14 miles to 18.
