Porsche just announced some major changes for the 2014 Panamera sedan, including replacing the naturally aspirated 4.8-liter V-8 on the S models with a new twin-turbo 3.0-liter V-6, good for a plenty-potent 420 hp and 384 lb-ft of torque, so other than the lustful throb of a V-8, those extra cylinders are not likely to be missed. Since the Panamera and Cayenne share much of their hardware, it appears Porsche's benchmark SUV may also get the hardware changes made on its sedan cousin.
Another possible addition to the Cayenne lineup could be a plug-in hybrid model, mirroring the just-announced Panamera S E-Hybrid, which updates the current Panamera Hybrid with the addition of 9.4 kWh lithium-ion battery, allowing for up to 20 miles of all-electric range. Considering the Cayenne's heavier weight and boxier aerodynamics, all-electric range would probably be slightly less, all else being equal.
Although the 2014 Panamera added a long-wheelbase model, all indications show the refreshed Cayenne will retain most of the key dimensions of the current model, and remain a two-row, five-seat model. Front and rear lighting and styling are slightly different than the current Cayenne, but the SUV's distinctive shape remains instantly recognizable. The Cayenne Diesel, which is already reportedly accounting for 30 percent of U.S. sales, will almost certainly remain part of the lineup.
