The last and probably biggest change to the Porsche Panamera we're going to talk about today concerns a switch of engines.
Starting with the 2014 model that will make its debut at the Shanghai Auto Show later this month, the Panamera S and 4S, as well as the newly introduced 4S Executive, will come with a twin-turbo 3.0-liter V6.
Both cars used to have 4.8-liter V8 engines before, producing 400 PS, but the switch to a forced induction V6 means they are much more economical now.
The new V6 makes 420 PS, 20 more than the old S models and 120 more than what's on offer with the base 3.6-liter V6. Torque has also been improved to 520 Nm available over a winder range.
An 18 percent improvement in fuel efficiency has been achieved through this, but also through the extended start-stop function now deactivates the engine when coasting to a stop. It sounds like a really strange and unnatural thing to do, but Porsche probably found a way to do this seamlessly.
With the exception of the Panamera GTS, models with PDK also offer a coasting function in which the clutches open in overrun, the engine idles, and the vehicle coasts freely.
