Porsche is expanding its Panamera range less than six months after the covers came off the second-generation model.

On Wednesday at the 2016 Los Angeles auto show, the German sports car marque introduced a base Panamera model as well as a long-wheelbase Executive option.

They join the Panamera 4S, Panamera 4 E-Hybrid and Panamera Turbo models that Porsche has already shown.

Power in the base Panamera still comes from a V-6, albeit a turbocharged 3.0-liter unit instead of the previous generation’s naturally-aspirated 3.6-liter V-6. Peak output is 330 horsepower, or 20 hp more than before. Drive is to the rear wheels only in this model, though Porsche offers a Panamera 4 with all-wheel drive.

As for the long-wheelbase Executive option, this is available strictly on all-wheel-drive Panameras, meaning the Panamera 4, Panamera 4S, Panamera 4 E-Hybrid and Panamera Turbo. It adds an extra 5.9 inches to the wheelbase, with pretty much all of that benefiting rear-seat passengers.

The Executive option is really designed for China’s chauffeur-driven class and includes comfort features such as heated seats with multi-way electrical adjustment, a roll-up sunblind, and an available rear-seat entertainment package with 10.1-in displays integrated into the backrests of the front seats.

Deliveries of the second-generation Panamera commence in January 2017. The first models to arrive will be the Panamera 4S and Panamera Turbo, priced from $100,950 and $147,950 respectively. Availability and pricing information for the other models will be announced at a later date.
