There are a few key visual differences to the GTS models thanks to the Sport Exhaust with blacked-out tailpipes and other darkened bits.
For the first time in a Panamera, a head-up display is also offered.
Inside the Alcantara and anodised aluminium cabin, the standard package includes a heated multifunction sports steering wheel with shift paddles and Alcantara trim, and the Connect Plus module for digital services. It rides on three-chamber adaptive air suspension, and sits 10mm lower than the standard vehicle thanks to the PASM adaptive chassis system.
As is typical with a GTS-trim vehicle, the standard equipment list is a greatest hits album of the standard Panamera's options list.
Porsche says that compared to the previous version of the Panamera GTS the new model gets significant upgrades, as well as a special package called Sport Design.
The newbies both pack a 4.0-liter twin-turbo V-8 engine that delivers 453 horsepower and 457 pound-feet of torque.
The engine is mated to an eight-speed PDK dual-clutch gearbox and Porsche Traction Management all-wheel-drive system, and flat out the GTS should be good for a 4.1 second 0-100km/h sprint and top speeds of up to 292km/h, according to Porsche. Air springs and adaptive dampers (Porsche Adaptive Suspension Management, or PASM) are standard but feature a custom calibration for the GTS and a 0.4-inch-lower ride height.
Another first for the Panamera GTS is the heads-up display, which projects all relevant information onto the windshield in full colour.
The world has changed since people first raised hell about Porsche building a four-door saloon, and these days the Panamera is one of the fanciest and fastest ways to rocket four people around in sumptuous style. This was followed by the 924 GTS and 928 GTS, which cultivated the concept throughout the 1980s and 90s.
The Porsche Panamera lineup is growing as the company has taken the wraps off the 2019 Panamera GTS. In 2007, the GTS celebrated its revival with the Carrera GTS.
