While taking in the 2015 Jaguar XJ's grand exterior styling and rich interior detailing, it can take a moment to realize that the interior isn't all that spacious.
In the back seat, especially, the style-forward roofline factors into what's likely the most snug fit of any of the premium luxury sedans. It's roughly the same size as the last-generation XJ, at least in overall length and wheelbase, but the body's so radically different and so tapered, there's lots of cubic feet of interior space left under the glass, where passengers don't sit. Long-wheelbase models add five inches at the floor, but the space across and above changes very little.
Those in front won't feel too cramped, though--save for a little constricted feel at the knees due to the wide center console. The seats are firmer and far better contoured and bolstered than they were in Jaguars past. Massage and heating functions are on offer, and they have 20-way power adjustments in front.
As for materials and trims inside, there might just be a few too many shiny pieces. Smothered in chrome, wood and leather, the cabin can read achingly gorgeous and slapdash all at once. At the same time, when it's trimmed in striped wood, nothing else in the class comes near its Hollywood Regency-like ambiance.
One other point worth noting is that the back seat in the XJ feels as well-trimmed and finely detailed as the dash and instrument panel--as opposed to some of the top German flagships, where back-seat appointments can feel rather stark and sanitized.
Trunk space is vast, and the trunklid powers open to 18.4 cubic feet, with a flat floor.
