STUTTGART, Germany – Porsche adds six new models to the second-generation Panamera lineup as production of the 5-door liftback ramps up at the automaker’s Leipzig manufacturing plant following its introduction earlier this year.

Included is a pair of price-leading models in the form of the rear-wheel-drive Panamera and all-wheel-drive Panamera 4. They are joined by a quartet of long-wheelbase, all-wheel-drive models: the Panamera 4 Executive, Panamera 4 E-Hybrid Executive, Panamera 4S Executive and Panamera Turbo Executive.

The new Panamera models make their public premiere at next week’s Los Angeles auto show ahead of North American deliveries starting in 2017.

The rear-wheel-drive Panamera and all-wheel-drive Panamera 4 are powered by Porsche’s latest twin-scroll-turbocharged 3.0L V-6 gasoline engine. Shared with the Audi S4, S5 Coupe and S5 Sportback, it produces 20 hp more than the older naturally aspirated 3.6L V-6 used by the first-generation Panamera and Panamera 4 at 325 hp.

In the standard-wheelbase Panamera models, the new V-6, which forms part of a new range of units developed in an engineering joint venture between Porsche and Audi, is claimed to provide fuel savings of up to 3.0 mpg (1.3 km/L) over its predecessor under European test conditions, although official consumption figures are yet to be revealed.

The new V-6 gasoline engine also is offered in the Panamera 4 Executive, which receives a 5.9-in. (150-mm) longer wheelbase than the current standard-wheelbase Panamera models at 122.0 ins. (3,100 mm), giving it an overall length of 204.7 ins. (5,200 mm).

Farther up the range, with similar dimensions, is the  Panamera 4S Executive running a more highly tuned twin-turbocharged 2.9L V-6 version of the joint-venture Porsche/Audi engine with 434 hp and the Panamera Turbo Executive fitted with a 542-hp twin-turbo 4.0L V-8.

Also available is the Panamera 4 E-Hybrid Executive. It runs Porsche’s twin-turbo 2.9L V-6 engine in combination with an electric motor mounted in the front of the new Porsche’s standard 8-speed automatic gearbox for an overall output of 456 hp.

The four new long-wheelbase Panamera Executive models are more highly equipped than their current standard-wheelbase siblings. Among their standard features is a panoramic roof, heated front and rear electronically adjusted seats and an adaptive air suspension with variable damper control as part of Porsche’s Porsche Active Suspension Management system.

The Panamera 4S Executive and Panamera Turbo Executive also receive rear-wheel steering and soft-close doors, with the latter also adding four-zone climate control, LED main-beam headlamps with Porsche Dynamic Light System and ambient lighting.

As an option, the all new-for-ʼ17 Panamera Executive models are available with a newly developed rear center console. It can be equipped with two integrated folding tables and an antenna connection for smartphones.

The new center console is offered alongside the latest generation of Porsche’s rear-seat entertainment system. It includes removable two 10.1-in. (25.6-cm) tablet-style monitors set within the backrests of the front seats.
