Porsche's front-engined four-door Panamera is getting a performance boost with the new 2019 Panamera GTS Sport Tourismo. The 4-liter twin-turbo V8 has 20 more horsepower and 73 lb-ft of torque than the previous model, connected to Porsche's superb dual-clutch PDK transmission. Those eight gears send power to all four wheels and make the Panamera good for a 0-60 time of 4.1 seconds. An active air suspension with a reworked Active Suspension Management system comes standard, along with a 10mm lower ride height and larger brakes front and rear. A new HUD system is available, and the interior comes trimmed in Alcantara and aluminum accents. The Panamera GTS and GTS Sport Tourismo are available to order now from Porsche dealers across North America.
