I’m currently at Stuttgart airport on the way back from a detailed technical briefing on the Porsche Panamera.

As luck would have it, it wasn’t just about seeing the car broken down to its component pieces (although that was fascinating).

The programme also included three quick laps of the test track at Porsche’s Development Centre in Weissach.

Firstly, the car is more convincing in the flesh than you might have expected. Secondly, this mighty machine was conceived, in Porsche’s own words, as ‘maximum width combined with minimum height’.

Thirdly, and perhaps most unexpectedly, the interior design and the interior packaging are just fantastic. A strict four-seater, the Porsche Panamera is very easy to get in and out of as well as having extraordinary amounts of head, shoulder and knee room.

Because Porsche has thought long and hard about the rear-seat passengers, the front seats have been designed to be as narrow as possible so the view forwards is as panoramic as possible. Despite the low roof and coupe profile, I didn’t feel the least bit hemmed in.
