What are they like inside?

They could barely be more different. The Porsche Panamera is a pure four-seater with a huge console running along its centre. It’s stylish, but has so many buttons that it’s distracting – you have to look down to ensure you’re pushing the correct one.

Stepping into the Jaguar XFR is like entering a cool art-house bar, with its soft blue lighting and blend of wood and aluminium. Every time you start an XFR it feels like an event – the pulsating heartbeat of the start button, swivelling vents and rising gear selector all contribute to the feeling that the car is coming to life around you.

Both cars seat four people in comfort (the Jaguar will do five at a pinch), but the Panamera has far more room for all. It also has sculpted seats, while the XFR’s are flatter and less supportive.

The Panamera has the edge for sheer depth of quality, too. Where the XFR has an air of style over substance, with the flashy, feel-good elements of the interior distracting you from some slightly cheaper, scratchier plastics lower down on the dashboard, the Panamera feels like a truly high-quality product all round.

As a result, it’s the Porsche that wears its miles better, with the Jaguar’s interior more susceptible to scratches and marks from heavy use. You’ll also find the seats in the XFR are a little more liable to sag and lose their shape with high mileage than those in the Panamera.

The XFR has a larger boot with the rear seats up, but the Panamera’s is bigger with them down – and it has the added practicality of its large, hatchback-style opening.
