The German manufacturer is expanding its Panamera line with a new version of the Turbo S grand touring sedan, which now has an additional 20hp under the hood for a total power of 570hp.

Powered by a 4.8L V8 biturbo engine, the new Porsche Panamera Turbo S accelerates from 0 to 100km/h in 3.8 seconds and can reach top speeds of around 310km/h. Porsche announces the car’s fuel consumption at 10.2L/100km, which is equivalent to CO2 emissions of 239g/km.

Among the standard features on the new Turbo S, Porsche provides a number of its latest driving aids and technologies, such as Porsche Active Suspension Management (PASM), Porsche Dynamic Chassis Control (PDCC) and Porsche Ceramic Composite Brakes (PCCB). On the inside, drivers and passengers can stay cool thanks to ventilated seats and ride in style on two-tone leather upholstery.

In addition to the standard version of the new Porsche Panamera Turbo S, an Executive edition will also be available, with a wheelbase expanded by 15cm for enhanced comfort. The two new models will be available from early 2014 at $180,300 and $200,500 respectively in the US.

The Panamera line also includes Porsche’s first plug-in hybrid vehicle, the Panamera S E-Hybrid, which arrived at dealers over the summer of 2013.

This more eco-friendly Panamera consumes just 3.1L/100km over the European driving cycle, resulting in CO2 emissions of 71g/km. The model is available from $99,000 in the US, or €112,309 in Europe.
