Like the Boxster, the Cayman is much quieter overall than its predecessor, though tire noise still makes its presence known at freeway speeds. Unlike the Boxster, gear whine from the rear of the car is also noticeable, owing to the hatch area's extension to the rear bumper. Even so, the new Cayman is noticeably quieter and more refined than the one that came before it--and not beyond the pale of competitive cars in its performance/price class.
Otherwise, the interior of the Cayman is very impressive. Quality leathers, excellent plastics, and the general level of fit and finish give a nod to the price premium a Porsche buyer is likely to pay. There's no aspect of the cabin that doesn't speak of well-built, well-engineered quality.
The seats are comfortable, with ample leg, head, and shoulder room for taller and larger occupants. The driver's seat and steering wheel are widely adjustable to suit a wide range of body sizes and types as well. There's not much gear-storage space in the cabin--small door pockets and a compact center console bin--but the rear hatch area and the front trunk do offer reasonable space for gear that doesn't need to be accessible during the drive.
A high-resolution, 7-inch touchscreen in the center console handles the Porsche Communication Management (infotainment) system, including audio, navigation, and other duties. A grid of buttons below the screen also offer direct access to various aspects of the Cayman's cabin systems.
