We’ve reported on the Porsche Panamera facelift, but here’s a live gallery post from Auto Shanghai 2013, where the big Porsche made its world debut. Also shown for the first time are new variants Panamera S E-Hybrid and the Executive long-wheelbase model.

External revisions include a tauter looking front end, with a new bumper offering larger air intakes and a more distinctive transition to the headlamps. The car also gets a redesigned rear section, with revised boot lid, new LED tail lights and a more swept-back rear window the fresh bits. Standard features now include items such as bi-xenon headlights and an automatic boot lid.

The new Panamera S E-Hybrid, which replaces the pre-facelift S Hybrid, has 416 hp of total system power, up from 380 hp. The electric drive itself offers 95 hp (70 kW), double the power of the S Hybrid’s 47 hp (34 kW) one, and a lithium-ion battery replaces the nickel metal hydride unit.

Porsche says that the plug-in hybrid can be charged within around 2.5 hours via the integrated on-board charger and the standard Porsche Universal Charger (AC), and less than four hours when connected to a conventional household electrical outlet.

The Panamera S E-Hybrid has an all-electric driving range of around 18 to 36 km in everyday operation, depending on conditions, and can achieve speeds of up to 135 km/h in EV mode. Other figures include a 0-100 km/h time of 5.5 seconds and a 270 km/h top speed.

The LWB Executive option for the Panamera Turbo and Panamera 4S (for left-hand drive markets only) features a 15 cm longer wheelbase and air suspension as standard, resulting in improved rear seating space and better ride comfort, two values not commonly attributed to Porsche’s four-door. As usual, two individual rear bucket seats are standard.

The Panamera Executive was created with China in mind, and why not, since it is Porsche’s second largest single market after the USA and the world’s biggest consumer of both the Cayenne and Panamera models.
