Leg, shoulder, and knee room are impressive in the front seats, roomier than nearly anything else in its class. Head room is improved from past models, despite the low arch of the roofline. The seats are comfortable and highly adjustable, allowing most body types to achieve a good fit, and there's even an adjustable bottom cushion to support longer legs. For the driver, a tilt-telescope steering wheel helps achieve the perfect driving position.
In Touring and XKR-S models, heated front seats are standard, and Portfolio models add ventilation.
The rear seat, as mentioned, is best reserved for cargo, but will serve for children and very small adults in a pinch, provided the front-seat passengers are willing to give up some leg room. We estimate the maximum occupant height of the back row at about 5'5".
The trunk is likewise small, though coupes fare better than convertibles, with 11 cubic feet of space to the drop-tops' 9. Convertibles also suffer with a smaller trunk area opening, further limiting the capacity. The style-focused rear end looks great, but leaves little room for hard-sided suitcases--weekend getaways will be best achieved with soft, and smallish, duffels.
These physical traits aside, the XK's cabin is both beautiful and comfortable. Glossy wood trim or brushed aluminum accent the superbly stitched leather and plush carpeting, giving the sense of a car that's worth twice the XK's price.
