Porsche unveiled its new second-generation 2017 Panamera sedan June 28, a car it says blends “the performance of a genuine sports car and the comfort of a luxury sedan.”

The most noticeable characteristic of the redesigned Panamera may be its lower, more gradually sloped rear end, which Porsche admits was designed to echo the iconic silhouette of its 911 sports car and which it says does not reduce headroom.

The wheelbase is slightly longer, with the inches added removed from the front overhang for a similar overall length. Height is up slightly, though the car generally looks lower and longer thanks to several design tricks.

All of the available engines in the new Panamera have been made both more powerful and more efficient, and Porsche’s even introducing two new biturbo engine offerings for 2017, a 440-hp V6 for the 4S, and a 550-hp V8 for the Turbo.

Both come available in AWD and with an eight-speed PDK transmission, and set the turbos in the valley between the cylinder banks for a lower mounting position and center-of-gravity, as well as for better throttle response.

Drivers can nail 100 km/h from zero in just 3.8 seconds in the new Turbo, or even 0.2 seconds quicker if the Sport Chrono Package is equipped. Top speed is 306 km/h, and fuel economy (using the European testing model) is roughly 9.3 L/100 km. Porsche’s first-ever use of cylinder deactivation in the V8 Turbo makes it a little easier to hit those numbers.

The V6 delivers the same sort of acceleration in a timespan of 4.4 seconds, can continue on to a top speed of 289 km/h, and returns about 8.1 L/100 km.

Porsche says the chassis under the Panamera has been similarly refined, giving drivers the option to select a racecar feel or a more luxurious ride.

A host of acronyms helps to that end – specifically Porsche Active Suspension Management (PASM) electronic damper control, a Porsche Dynamic Chassis Control Sport (PDCC Sport) system, and Porsche Torque Vectoring Plus (PTV Plus) and active roll stabilization – as does the new electromechanical steering system and 918 Spyder-influenced rear axle steering.

The interior is built around the Porsche Advanced Cockpit concept, which means persons resting in the very low driver seat will see two seven-inch displays directly ahead of them, flanking an analog tachometer. A 12.3-inch center console screen breaks up driver and passenger spaces, and handles new Apple CarPlay and voice control responsibilities.

Massage seats are optional, as is ambient lighting and a 3D high-end sound system from Burmester.

Porsche is taking orders in Canada now, though the first new Panameras won’t show up until early 2017. Pricing will begin at $114,300 for the Panamera 4S and $167,700 for the Panamera Turbo in Canada.
